h1. Introduction

This version of the component is based on:
* [Flowable|https://www.flowable.org/] v6.4.2 as embedded BPMN engine. Flowable extensions can be used at the runtime level,
* [Eclipse Jetty|http://www.eclipse.org/jetty/] v9.4.11.v20180605 as HTTP server for Flowable REST API.

h1. System requirements

The Petals SE Flowable *MUST* be deployed on a container running with a *Java Development Kit* (JDK), not a Java Runtime Environment !!

h1. Using the mode "service"

h2. About deployment/undeployment

h3. Deployment

A service unit embeds process definition(s). So when deploying a service unit, its process definition(s) are automatically deployed, and the associated consumer services are registered.

A process definition can be undeployed only when no more process instance is in progress and when no more historic process instance exists. That's why process definition are not undeployed when undeploying a service unit. You can undeploy a process instance using the administrative JMX operation '{{undeployProcessDefinition}}'.

Next, if you redeploy the service unit, the embedded process definition(s) will not be redeployed because the process definition is already deployed for the given version. In this way, we can push some changes outside process definition as service consumer parameters (timeout, ...). If some changes are needed into process definition(s), it is needed to increment the association version.

According to changes into your process definition, it can be required to create new version of your associated service providers:
* if your changes concern all BPMN object except service task, you can undeploy your service unit and next you can deploy new version of your service unit including the new version of your process definition. Process instances started before the deployment continue to work fine because all service consumers can be resolved against your new service unit (service consumers are the same),
* if your changes include changes about service tasks, it will be needed to create new version of your service providers. All process instances in progress require to keep deployed your initial service unit to correctly invoke services. Your new process definition will be deployed with its own service unit. So we will have two service units deployed concurrently, so:
** names of service provider associated to service unit must be different,
** and service unit names must be different to be abler to deploy them on the same Petals ESB containe.

{note}When a Petals ESB node restarts, all service units previously deployed are redeployed. As process definition versions are the same no redeployment of process definitions occurs.{note}

With a Petals ESB topology based on at least two nodes, you can deploy the Petals SE Flowable on several nodes to have high availability on your service providers associated to your process definitions. As service tasks are executed by any SE Flowable through the Flowable job async executor, you must deployed all your service units on all your Petals SE Flowable having the Flowable job async executor enabled.

h3. Undeployment

A version of a process definition can be undeployed only if no more associated process instance exists, in progress or ended. If process instances exist, they must be purged before process definition undeployment.

Several administrative JMX operations can help you:
|| Administrative JMX operation || Description ||
| {{listPurgeableProcessInstances}} | List all purgeable process instances of the given process definition. A purgeable process instance is a process instance that is terminated. The list of identifiers of purgeable process instances is returned. |
| {{purgeProcessInstance}} | Purge a process instance deleting all its data. This operation returns all flow instance identifiers associated to the process instance that can be used to purge MONIT traces in a next step. |
| {{undeployProcessDefinition}} | Undeploy a process definition. |

h2. Creating a service-unit for a process definition

h3. Creating the service contract

The SE Flowable provides a service with several operation for a process definition. A WSDL is associated to this service. This WSDL can be written freely. The user can use its own namespace, its own names, ... It is only constraint by the following rules:
* the operations of the binding section *are annotated* to link them to the supported operations of the process definition (create an instance of the process definition, complete the current task of the process instance, ...)
* the parameters of the operation *are annotated* to retrieve the right values to transmit to the BPMN engine,
* the output and fault of the operations *are annotated* to build the service output from the result of the operation on the BPMN engine side.

{tip}For a unit test purpose, an extension of JUnit is available to validate your WSDL not only in a our WSDL point of view, but also in a SE Flowable point of view. See chapter "[Unit testing|#Unit_Testing]".{tip}

h4. Identifying operations

The mapping between operations of the WSDL and operations supported by the BPMN 2.0 engine embedded in the SE Flowable is declared using a dedicated binding. The binding "Flowable" is done adding the element {{\{http://petals.ow2.org/se/flowable/annotations/1.0}operation}} to the element operation of the binding. Its attribute *{{action}}* defines the operation that will be executed on the process engine according to the following values:
|| Value of {{action}} || Operation executed on the process engine ||
| {{startEvent}} | Create a new instance of the process. See [petalscomponents:Associating an operation to the creation of an process definition instance|#associating_startEvent] for more information on this operation. |
| {{userTask}} | Complete a user task. See [petalscomponents:Associating an operation to the completion of a process instance task|#associating_userTask] for more information on this operation. |
| {{intermediateMessageCatch}} | Catches an intermediate message. See [petalscomponents:Associating an operation to the catching of an intermediate message|#associating_intermediateMessageCatchEvent] for more information on this operation. |

The action is completed with the another attribute as following:
|| Value of {{action}} || Extra attributes ||
| {{startEvent}} | According to the nature of your start event step, you must use the following extra attribute to identify it:
* {{none-start-event-id}}, for none start event step, it will contain the identifier of the none start event step in the process definition,
* {{start-event-message-name}}, for message start event step, it will contain the name of the message in the process definition that fires this start event step. |
| {{userTask}} | The identifier in the process definition of the user task to complete associated to the operation is given through the extra attribute {{user-task-id}}. |
| {{through the extra attribute {{user-task-id}}. |}} | The message name in the process definition of the intermediate message catch event associated to the operation is provided through this extra attribute. |

h4. Identifying input parameters of operations

In the same way, input parameters of operations are mapped through annotations placed inside of the binding operation. Two natures of input parameters exists:
* the expected input parameters
* and, variables.

Each BPMN 2.0 engine API operation can require mandatory or optional input parameter, the expected input parameters, and can accept to set several variables in the same time.

Expected input parameters are declared using dedicated annotation according to the operation:
|| Value of the attribute {{action}} of the annotation {{flowable:operation}} || Operation executed on the process engine ||
| {{startEvent}} | Expected input parameters are:
* the process identifier,
* the user identifier.
See [petalscomponents:Associating an operation to the creation of an process definition instance|#associating_startEvent] for more information on the declaration of this parameter. |
| {{userTask}} | Expected input parameters are:
* the process instance identifier,
* the user identifier.
See [petalscomponents:Associating an operation to the completion of a process instance task|#associating_userTask] for more information on the declaration of these parameters. |
| {{intermediateMessageCatch}} | Expected input parameter is the process instance identifier. See [petalscomponents:Associating an operation to the catching of an intermediate message|#associating_intermediateMessageCatchEvent] for more information on the declaration of these parameters. |

Variables are identified by the annotation adding the element {{\{http://petals.ow2.org/se/flowable/annotations/1.0}variable}}:
* its attribute *{{name}}* defines the variable name used in the process definition.
* its content defines the value to set to the variable using an XPath expression.

{code}
<flowable:variable name="numberOfDays">
/*[local-name()='demande']/*[local-name()='nbJourDde']
</flowable:variable>
{code}

See operation details to know if variables can be set.
No extra check is done by the SE Flowable about the compliance of the variable with the process definition.

h4. Identifying output parameters of operations

Output parameters of the BPMN 2.0 engine API operation can not be mapped to the output reply of the service operation using a simple XPath expression as for input parameters. An XSL style-sheet is required to generated the full output reply. It is identified using the annotation adding the element {{\{http://petals.ow2.org/se/flowable/annotations/1.0}output}} that contains the XSL style-sheet name. The XSL style-sheet is read from the classloader or through a file relative to the root directory of the service unit. The XSL style-sheets are mainly located in the service-units, they can also be packaged as a shared library.

According to the operation executed by the BPMN 2.0 engine, its output parameters are transmitted to the XSL style-sheet through XSL parameters. You will use these XSL parameters to generate your service reply from your service request payload. See operation details to know the available XSL parameters.

{tip}For a unit test purpose, an extension of JUnit is available to test your XSL. See chapter "[Unit testing|#Unit_Testing]".{tip}

h4. Identifying faults of operations

When an error occurs on the BPMN engine side, this error can be returned as business fault or technical error. The business faults are declared into the WSDL of the service.

The mapping of an error of the BPMN engine to a business fault is defined using the annotation {{\{http://petals.ow2.org/se/flowable/annotations/1.0}fault}} set as child element of the WSDL fault. The attribute {{name}} will contain a key word identifying the error on the BPMN engine. And the content value is the name of the XSLT style-sheet to use to generate the business fault.

The XSL style-sheet is read from the classloader or through a file relative to the root directory of the service unit. The XSL style-sheets are mainly located in the service-units, they can also be packaged as a shared library.

An error of the BPMN engine that can be mapped to a business fault has also parameters that will be transmitted to the XSL to generate the right business fault content.

See operation details to known the errors thrown, and their parameters, that can be mapped to a business fault.

{tip}For a unit test purpose, an extension of JUnit is available to test your XSL. See chapter "[Unit testing|#Unit_Testing]".{tip}

{anchor:associating_startEvent}
h4. Associating an operation to the creation of an process instance

The operation creating instances of process definition is identified by the value *{{startEvent}}* set on the attribute {{action}} of the annotation {{\{http://petals.ow2.org/se/flowable/annotations/1.0}operation}}. As your service unit can include several process definition, you need to clarify the process definition to use to create the process instance using the attribute *{{processDefinitionId}}*. As a process definition can include several start events, the right start event to use to create the new process instance is clarified with attributes:
* *{{none-start-event-id}}* for none start event,
* or *{{start-event-message-name}}* for message start event.

This operation accepts variables and requires the following input parameters:
* user identifier, declared using the annotation {{\{http://petals.ow2.org/se/flowable/annotations/1.0}userId}} containing an XPath expression that is applied on incoming XML payload to get the value of the user identifier to use on the BPMN engine side.

The XSL parameters available to generate the service output reply are:
|| XSL parameter name || Type || Description ||
| \{http://petals.ow2.org/se/flowable/output-params/1.0/special}processInstanceId | String | Identifier of the process instance created |
| \{http://petals.ow2.org/se/flowable/output-params/1.0/special}userId | String | The user identifier used to create the process instance |
| \{http://petals.ow2.org/se/flowable/output-params/1.0/process-instance}variable-name | String | Process instance variables. <variable-name> is the name of a process instance variable. |

On this operation, no error thrown by the BPMN engine can be mapped to business fault.

It is possible to map several operations of the WSDL to the creation of process instances, but this has perhaps no sens.

{anchor:associating_userTask}
h4. Associating an operation to the completion of a process instance task

The operation completing a task of a process instance is identified by the value *{{userTask}}* set on the attribute {{action}} of the annotation {{\{http://petals.ow2.org/se/flowable/annotations/1.0}operation}}. To guarantee that the expected user task is the right one, its identifier is clarified with the attribute *{{user-task-id}}*.

This operation accepts variables and requires the following input parameters:
* process instance identifier, declared using the annotation {{\{http://petals.ow2.org/se/flowable/annotations/1.0}processId}} containing an XPath expression that is applied on incoming XML payload to get the value of the process instance identifier to use on the BPMN engine side.
* user identifier, declared using the annotation {{\{http://petals.ow2.org/se/flowable/annotations/1.0}userId}} containing an XPath expression that is applied on incoming XML payload to get the value of the user identifier to use on the BPMN engine side.

Note: The completion status of the task is a variable and so it takes any form.

The XSL parameters available to generate the service output reply are:
|| XSL parameter name || Type || Description ||
| \{http://petals.ow2.org/se/flowable/output-params/1.0/special}processInstanceId | String | Identifier of the process instance created |
| \{http://petals.ow2.org/se/flowable/output-params/1.0/special}userId | String | The user identifier used to create the process instance |
| \{http://petals.ow2.org/se/flowable/output-params/1.0/process-instance}variable-name | String | Process instance variables. <variable-name> is the name of a process instance variable. |
| \{http://petals.ow2.org/se/flowable/output-params/1.0/task}variable-name | String | Task local variables. <variable-name> is the name of a task local variable. |

The following errors thrown by the BPMN engine can be mapped to business fault:
|| Error || Description || XSL parameters ||
| {{TaskCompletedException}} | The associated user task is already completed | * process instance identifier: \{http://petals.ow2.org/se/flowable/faults/1.0}processInstanceId
* task identifier: \{http://petals.ow2.org/se/flowable/faults/1.0}taskId |
| {{ProcessInstanceNotFoundException}} | No active process instance found for the given process instance identifier | process instance identifier: \{http://petals.ow2.org/se/flowable/faults/1.0}processInstanceId |
| {{UnexpectedUserException}} | The task to complete is assigned to another user identifier | * process instance identifier: {{\{http://petals.ow2.org/se/flowable/faults/1.0}processInstanceId}}
* task identifier: \{http://petals.ow2.org/se/flowable/faults/1.0}taskId
* user identifier: \{http://petals.ow2.org/se/flowable/faults/1.0}userId |

A such operation is defined for each task of the process definition to complete. {color:red}*C'est le cas d'un service par tache à terminer. Essayer de mieux expliquer.*{color}.

{anchor:associating_intermediateMessageCatchEvent}
h4. Associating an operation to the intermediate message catch event

The operation receiving an intermediate message event identified by the value *{{intermediateMessageCatch}}* set on the attribute {{action}} of the annotation {{\{http://petals.ow2.org/se/flowable/annotations/1.0}operation}}. To guarantee that the expected intermediate message catch event is the right one, the message name is clarified with the attribute *{{message-event-name}}*.

*Caution*: The value of {{{{message-event-name}} is the message name that should be received in the BPMN definition, not the identifier of the intermediate message catch event. For the following BPMN definition the value will be '{{messageName}}':
{code:xml}
<definitions ...>
<process id="intermediate-message-catch-event-process" name="My process" isExecutable="true">
...
<intermediateCatchEvent id="messageintermediatecatchevent1" name="MessageCatchEvent">
<messageEventDefinition messageRef="messageRef"/>
</intermediateCatchEvent>
...
</process>
<message id="messageRef" name="messageName"/>
</definitions>
{code}

This operation accepts variables and requires the following input parameters:
* process instance identifier, declared using the annotation {{\{http://petals.ow2.org/se/flowable/annotations/1.0}processId}} containing an XPath expression that is applied on incoming XML payload to get the value of the process instance identifier to use on the BPMN engine side.

This operation is limited to the JBI MEPs: InOnly and RobustInOnly. So no output reply is returned, only fault and error according to the MEP.

The following errors thrown by the BPMN engine can be mapped to business fault:
|| Error || Description || XSL parameters ||
| {{ProcessInstanceNotFoundException}} | No active process instance found for the given process instance identifier | process instance identifier: \{http://petals.ow2.org/se/flowable/faults/1.0}processInstanceId |
| {{UnexpectedMessageEventException}} | No catcher is expecting the intermediate message event on BPMN engine side | * process instance identifier: \{http://petals.ow2.org/se/flowable/faults/1.0}processInstanceId
* message name: \{http://petals.ow2.org/se/flowable/faults/1.0}messageName |
| {{MessageEventReceivedException}} | The intermediate message event has already been caught on BPMN engine side | * process instance identifier: \{http://petals.ow2.org/se/flowable/faults/1.0}processInstanceId
* message name: \{http://petals.ow2.org/se/flowable/faults/1.0}messageName |

A such operation can be defined for each intermediate message catch event of the process definition to complete. Don't forget to define the variable types in the WSDL.

{code}

h4. Associating an operation to retrieve process instances

The operation retrieving process instances is identified by the value *{{retrieveProcInst}}* set on the attribute {{action}}:
{code}
<wsdl:binding name="Order" xmlns:flowable="http://petals.ow2.org/se/flowable/annotations/1.0">
<wsdl:operation name="searchOrder" type="...">
<flowable:operation action="retrieveProcInst" />
<flowable:input-parameter name="isActive" value="/searchOrderRequest/isInProgress" />
<flowable:input-parameter name="responsibleUser" value="/searchOrderRequest/responsibleUser" />
<flowable:input-parameter name="responsibleGroup" value="/searchOrderRequest/responsibleGroup" />
<flowable:output>searchOrderOutput.xsl</flowable:output>
<wsdl:input/>
<wsdl:output/>
</wsdl:operation>
</wsdl:binding>
{code}

This operation requires the following input parameters:
|| Input parameter name || Type || Description || Required ||
| isActive | Boolean | Only active task are returned. | No |
| responsibleUser | String | Only select tasks for which the given user is a candidate are returned. | No |
| responsibleGroup | String | Only select tasks for which users in the given group are candidates are returned. | No |
It does not use variables.

The process instances returned by the component are all associated to the current process definition (the process definition packaged in the service unit).

The XSL parameters available to generate the service output reply are:
|| XSL parameter name || Type || Description ||
| processInstances | {color:red}Quel type 'list' est exploitable coté XSL{color} | The list of process instance identifier matching criteria. |

It is possible to map several operations of the WSDL to search process instance, for example with different search criteria.

h3. Creating the service unit

All services provided by a business process are defined into the JBI descriptor of a service unit as a section '{{provides}}':
{code}
<jbi:provides
interface-name="process:vacation"
service-name="process:vacationService"
endpoint-name="autogenerate">

<petalsCDK:wsdl>vacationService.wsdl</petalsCDK:wsdl>

<petals-se-flowable:tenant_id>my-tenant</petals-se-flowable:tenant_id>
<petals-se-flowable:category_id>samples</petals-se-flowable:category_id>
<petals-se-flowable:process_file1>vacationRequest.bpmn20.xml</petals-se-flowable:process_file1>
<petals-se-flowable:version1>1</petals-se-flowable:version1>

</jbi:provides>
{code}

{note}Only one section '{{provides}}' is accepted by the Petals SE Flowable.{note}

If your business process includes service tasks to invoke service providers, you can add a section '{{consumes}}' for each one to drive more precisely the invocation:
{code}
<jbi:provides ...>
...
<petals-se-flowable:process_file1>vacationRequest.bpmn20.xml</petals-se-flowable:process_file1>
<petals-se-flowable:version1>1</petals-se-flowable:version1>
</jbi:provides>

<jbi:consumes
interface-name="archiveService:archive"
service-name="archiveService:archiveService">
<petalsCDK:timeout>15000</petalsCDK:timeout>
<petalsCDK:mep>RobustInOnly</petalsCDK:mep>
<petalsCDK:operation>archiveService:archiver</cdk:operation>
</jbi:consumes>
{code}

Supported parameters of the section '{{consumes}}' are:
* {{timeout}}, to set on the message exchange used for the service provider invocation,
* {{mep}}, that define the message exchange pattern to use. If not set, the pattern used isthe one defined in the imported WSDL,
* {{operation}}, should be used if several operations of the same consumer are invoked by the process. You can add several section 'consumes' for the same consumer but for different operations.
* {{exchange-properties}}, the properties to set on the message exchange used to invoke the service provider,
* {{message-properties}}, the properties to set on the message of message exchange used to invoke the service provider.

{tip}If you want specify a specific endpoint to invoke a service provider, just define it in the section '{{consume}}':
{code}
<jbi:consumes
interface-name="archiveService:archive"
service-name="archiveService:archiveService"
endpoint-name="mySpecificEndpointName">
<petalsCDK:timeout>15000</petalsCDK:timeout>
</jbi:consumes>

| category_id | Deployment category identifier. For example to group business processes. | {{myCategory}} | No |
| process_file | Name of the process definition file into the service unit (relative to the root of the service unit). \\
To deploy several process definition files use {{process_file<X>}} where {{<X>}} is a number starting to 1. {{process_file<X>}} must have its own {{version<X>}}. | - | Yes |
| version | Version of the process definition. | - | Yes |

The Petals service providers can be invoked natively from Flowable process using a '{{ServiceTask}}' into your process definition through three steps:
# [petalscomponents:import the service contract of the Petals service provider into your service-unit project|#importing-service-contract],
# [petalscomponents:define the Petals service provider address|#defining-service-provider],
# [petalscomponents:create the associated service task|#creating-service-task],
# [petalscomponents:configure the associated service consumer|#configuring-service-consumer].

{anchor:importing-service-contract}
h2. Importing the service contract of the Petals service provider

The service contract of the Petals service provider (ie. its WSDL file) must be added to the service unit project. We recommend you to import the WSDL file in the same directory than the process definition file (ie. {{src/main/resources/jbi}}.

!import-wsdl-in-su-project.png!

{anchor:defining-service-provider}
h2. Defining the Petals service provider address

The address of the Petals service provider (ie. interface name, service name and/or endpoint) must be defined into the service contract previously imported, as a basic service endpoint in XML tag '{{/wsdl:service/wsdl:port/soap:address/@location}}'. The address is defined with an URL matching the following pattern: {{petals:///interfacename[:servicename[petalscomponents::endpointname]]}}.
Example:
{code:xml}
<wsdl:definitions ...>
...
<wsdl:service name="notifyVacationService">
<wsdl:port name="autogenerate" binding="notifyService:notifyVacationBinding">
<soap:address location="petals:///{http://petals.ow2.org/samples/se-flowable/notifyVacationService}notifyVacation" />
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
{code}

{anchor:creating-service-task}
h2. Creating the associated service task

Once a '{{ServiceTask}}' has been added to your process, you will configure it as following to invoke the right Petals service provider:
# First, import the Petals service provider contract into the Flowable process definition:
{code:xml}
<definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL" ...>
<import location="CommunicationService.wsdl" namespace="http://org.ow2.petals.samples.rld.service.technical.communication/1.0/"
importType="http://schemas.xmlsoap.org/wsdl/" />
<process id="shifting-summary-sending" name="Shifting summary sending process" isExecutable="true">
...
</process>
</definitions>
{code}
# Next, at your service task level, select the service task implementation '{{##WebService}}' and identify the reference of the service to call (ie. the operation of a web-service):
{code:xml}
<definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL" ...>
...
<process id="shifting-summary-sending" name="Shifting summary sending process" isExecutable="true">
...
<serviceTask id="getHRManagerEmail" name="Retrieve email of the human resource manager"
implementation="##WebService" operationRef="rldProcess:getHumanResourceManagerOp">
...
</serviceTask>
...
</process>
</definitions>

h2. Configuring the service consumer

The service consumer that invokes the service provider can be configured to adjust following parameters by operation:
* the message exchange pattern used: using MEP 'InOut' or 'RobustInOnly' forces the service task to wait the response of the service provider while MEP 'InOnly' ends the service provider without waiting the service provider acknowledgment,
* the timeout to apply on service invocation.

All needed information must be defined in the service-unit JBI descriptor. This JBI descriptor is configured through parameters divided in following groups:
* *JBI parameters* that defines the service provider identification,
* *CDK parameters* that are parameters driving the service consumer implementation at CDK layer,
* *CDK interceptor parameters* that are parameters driving interceptors at CDK layer.

Example:
{code:xml}
<jbi:jbi ...>

<jbi:services binding-component="false">
<jbi:provides ...>
...
</jbi:provides>

<jbi:consumes
interface-name="ns:my-interface"
service-name="ns:my-service">
<cdk:mep>InOut</cdk:mep>
<cdk:operation>tdt-helios-generique:creer</cdk:operation>
<cdk:timeout>360000</cdk:timeout>
</jbi:consumes>

<jbi:consumes ...>
...
</jbi:consumes>
...

</jbi:services>
</jbi:jbi>
{code}

If no service consumer configuration is found into the SU JBI descriptor for the invoked operation, the following default parameters are used:
* interface name, service name and endpoint name are the one defined on the location of the WSDL endpoint,
* the MEP is the one defined into the WSDL according to input, output and fault of the operation,
* the default timeout defined at CDK level.

{note}
_*Note about timeout on service provider invocation*_: it can be configured into the associated section '{{consumes}}' of the SU JBI descriptor but it has not to be too long otherwise the Flowable database transaction timeout will be fired. To invoke very long service provider you should use an asynchronous mechanism based on a service task launching your service provider and an intermediate catch event waiting the service provider reply:

h1. IDM engine integration

The Flowable engine requires an IDM engine in charge of managing users and groups. It is required by the user tasks that are assigned to users or groups.

Once you have selected your IDM engine implementation, just configure it (the configurator implementation) at component level through the parameters {{idm-engine-configurator-class-name}} and {{idm-engine-configurator-config-file}}. By default, the Petals SE Flowable uses a file-based IDM engine.

Available IDM engines are:
* file-based IDM engine where users and groups are stored into files,
* LDAP-based IDM engine where users and groups are managed into a LDAP directory,
* Petals service based IDM engine invoking Petals services to retrieve users and groups,
* you can also write your own IDM engine,
* in next versions, new IDM engines will be added.

h2. File-based IDM engine

This IDM engine is a demonstration IDM engine, that's why it is embedded into the Petals SE Flowable. It is based on two files, one containing the users, another containing the group definitions.

h3. Configuration

Parameters of the configuration file of this IDM engine are:
|| Parameter name || Description || Mandatory ||
| {{users-file}} | File name of the file containing the user declarations. If it is an existing absolute file name, the file is read as a file from the filesystem, otherwise it is read as a resource from the component classloader. | Yes |
| {{groups-file}} | File name of the file containing the user group declarations. If it is an existing absolute file name, the file is read as a file from the filesystem, otherwise it is read as a resource from the component classloader. | Yes |
| {{privileges-file}} | File name of the file containing the privilege declarations of users and groups. If it is an existing absolute file name, the file is read as a file from the filesystem, otherwise it is read as a resource from the component classloader. Privilege declarations are required by Flowable UIs or Flowable REST API| Yes, can be emty |

The file-based IDM engine includes a default configuration used when the IDM engine configurator configuration file is not set at the component level. This default configuration is inspired of Flowable itself defining users and groups as mentioned as examples below in file formats. No default provilege is granted.

h3. File formats

The user file is defined as following:
{code}
#
# Property format:
# <user-id> = <user-password>
#
kermit = kermit
fozzie = fozzie
gonzo = gonzo
{code}

The group file is defined as following:
{code}
#
# Property format:
# <group-id> = <user-id-1> <user-id-2> ... <user-id-n>
#
admin = kermit
manager = kermit gonzo
management = kermit gonzo
accountancy = kermit fozzie gonzo
engineering = kermit
sales = kermit gonzo
user = fozzie
{code}

h2. LDAP-based IDM engine

This IDM engine is the one provided by Flowable as modules {{flowable-ldap-configurator}} and {{flowable-ldap}}.

h3. Configuration

Parameters of the configuration file of this IDM engine are the ones of the Flowable LDAP configurator:
|| Parameter name || Description || Mandatory ||
| {{server}} | The server on which the LDAP system can be reached. | Yes |
| {{port}} | The port on which the LDAP system is running. | Yes |
| {{user}} | The user id that is used to connect to the LDAP system. | No |
| {{password}} | The password that is used to connect to the LDAP system. | No |
| {{baseDn}} | The base _distinguished name_ (DN) from which the searches for users and groups are started. | Yes |
| {{userBaseDn}} | The base _distinguished name_ (DN) from which the searches for users are started. If not provided, {{baseDn}} (see above) will be used. | Yes |
| {{groupBaseDn}} | The base _distinguished name_ (DN) from which the searches for groups are started. If not provided, {{baseDn}} (see above) will be used. | Yes |
| {{searchTimeLimit}} | The timeout that is used when doing a search in LDAP in milliseconds. Default value: 1 hour. | No |
| {{queryUserByUserId}} | The query that is executed when searching for a user by userId. Here, all the objects in LDAP with the class {{inetOrgPerson}} and who have the matching uid attribute value will be returned. As shown in the example, the user id is injected by using \{0}. For example: {{(&(objectClass=inetOrgPerson)(uid=\{0}))}} | Yes |
| {{queryUserByFullNameLike}} | The query that is executed when searching for a user by full name. Here, all the objects in LDAP with the class {{inetOrgPerson}} and who have the matching first name and last name values will be returned. Note that \{0} injects the firstNameAttribute (as defined above), \{1} and \{3} the search text and \{2} the lastNameAttribute. For example: {{(&(objectClass=inetOrgPerson)((\{0}=\{1})(\{2}=\{3})))}} | Yes |
| {{queryAllUsers}} | The query that is executed when searching on users without a filter. Here, all the objects in LDAP with the class {{inetOrgPerson}} will be returned. For example: {{(objectClass=inetOrgPerson)}} | Yes |
| {{queryGroupsForUser}} | The query that is executed when searching for the groups of a specific user. Here, all the objects in LDAP with the class {{groupOfUniqueNames}} and where the provided DN (matching a DN for a user) is a uniqueMember are returned. As shown in the example, the user id is injected by using \{0}. For example: {{(&(objectClass=groupOfUniqueNames)(uniqueMember=\{0}))}} | Yes |
| {{queryAllGroups}} | The query that is executed when searching on groups without a filter. Here, all the objects in LDAP with the class {{groupOfUniqueNames}} will be returned. For example: {{(objectClass=groupOfUniqueNames)}} | Yes |
| {{userFirstNameAttribute}} | Name of the attribute that matches the user first name. | Yes |
| {{userLastNameAttribute}} | Name of the attribute that matches the user last name. | Yes |
| {{groupIdAttribute}} | Name of the attribute that matches the group id. | Yes |
| {{groupNameAttribute}} | Name of the attribute that matches the group name. | Yes |

The LDAP-based IDM engine includes a default configuration used when the IDM engine configurator configuration file is not set at the component level. This default configuration is inspired of Flowable default configuration.

h2. Petals services based IDM engine

{color:red}TODO{color}

h2. Write your own IDM engine

You can write your own IDM engine. It will be available as a shared library that you will configure to be used by the Petals SE Flowable.

To implement it, just create a class implementing the interface {{org.ow2.petals.flowable.identity.SeFlowableIdmServiceConfigurator}} or extending the class {{org.ow2.petals.flowable.identity.AbstractProcessEngineConfigurator}}. You can find an example [here|https://github.com/petalslink/petals-se-flowable/blob/master/src/main/java/org/ow2/petals/flowable/identity/file/FileIdmEngineConfigurator.java] (the file-based IDM engine), or [here|https://github.com/petalslink/petals-se-flowable/blob/master/src/main/java/org/ow2/petals/flowable/identity/ldap/LdapIdmEngineConfigurator.java] (the LDAP-based IDM engine).

h1. Configuring the component

The component can be configured through the parameters of its JBI descriptor file. These parameters are divided in following groups:
* *JBI parameters* that have not to be changed otherwise the component will not work,
* *CDK parameters* that are parameters driving the processing of the CDK layer,
* *Dedicated parameters* that are parameters specific to this component.

h2. CDK parameters
The component configuration includes the configuration of the CDK. The following parameters correspond to the CDK configuration.

{include:petalscomponents:0 CDK Component Configuration Table 5.8.0}

h2. Interception configuration

{include:petalscomponents:0 CDK Component Interceptor configuration 5.8.0}

h2. Component specific parameters

These parameters drive features proposed by the component and configure the Flowable engine embedded in the SE:
* activation of the mode 'integration',
* Flowable engine configuration:
** the database parameters: your are responsible to provide this database according to your needs. And especially, you must assume that the database is highly available to have a SE Flowable highly available,
** asynchronous job executor activation and configuration,
** BPMN validation,
** identity service to use.

{anchor:job_executor}
h3. Enabling/disabling the Flowable job executor

Flowable requires a job executor to manage a couple of threads to fire timers, to invoke service tasks, other asynchronous tasks. At least one job executor is required.

When deploying several Petals SE Flowable running with the same database, you can disable the job executor on some Petals SE Flowable. Or even, you can specialized a Petals SE Flowable to process all asynchronous tasks enabling the job executor on only one Petals SE Flowable.

h2. Using placeholders to configure the process definition

The placeholders defined in the properties file of the SE Flowable can be used in the process definition. A dedicated map variable containing all placeholders is set when starting the process instance: *petalsPlaceholders*. If the placeholder '{{signaturePeriod}}' is defined, it can be used as following in the process definition:
{code:xml}
<intermediateCatchEvent id="waitBeforeGetStatus" name="Wait">
<timerEventDefinition>
<timeDuration>${empty execution.variableInstances.petalsPlaceholders.getValue().signaturePeriod ? "PT1H" : execution.variableInstances.petalsPlaceholders.getValue().signaturePeriod}</timeDuration>
</timerEventDefinition>
</intermediateCatchEvent>
{code}

{note}The dedicated map variable is automatically copied to be accessible as variable of sub-processes.{note}

h1. Business monitoring

MONIT traces are logged to each step of the BPMN process interacting with Petals ESB:
* when creating and terminating process instances,
* when starting and completing user tasks,
* when executing service task implemented through Petals services,
* when intermediate catch message event is waiting and receiving message.

The principle of the flow instance identifier of MONIT traces is to permit to retrieve all MONIT traces of a given process flow.

When creating a process instance, two flows are running:
* the flow from which the process instance creation request is coming,
* the flow associated to the process instance that will be created.

When completing a user task, two flow are running also:
* the flow from which the user task completion request is coming,
* the flow associate to the process instance for which the user task must be completed.

When a intermediate catch message event receives its message, two flow are running also:
* the flow from which the message receipt request is coming,
* the flow associate to the process instance for which the intermediated catch message event must be completed.

The service tasks are flow steps of the flow associated to the process instance.

So, we must be able to correlate the flow associated to the process instance with flows associated to interaction requests (process instance creation, user task completion):
{gliffy:name=MONIT trace correlations|size=M|version=6}
* on process instance creation, we have the following MONIT traces ordered:
## a MONIT trace associated to the start of the interaction request creating the process instance, with following attributes:

h2. Flow tracing activation

{include:petalscomponents:0 CDK SE Business Monitoring Flow Tracing Activation 5.8.0}

h2. Flow tracing propagation

On process instance creation, the current flow tracing activation is stored in the process instance into the variable '{{petals.flow.external.tracing.activation.state}}'. The flow tracing propagation from the process instance to a service provider (through a service task) is driven by the parameter propagate-flow-tracing-activation of the service consumer definition. If no parameter is defined at service consumer level, the component configuration parameter 'propagate-flow-tracing-activation' is used. Finally, by default, the flow tracing propagation is enabled.

h1. Logging

The traces of the BPMN 2.0 engine "Flowable" are activated through the logging configuration file of Petals ESB. The root logger for Flowable is {{org.flowable}}:
{code}
...
org.activiti.level=INFO
org.activiti.engine.impl.level=FINE
...
{code}

h1. Monitoring the component

h2. Using metrics

{anchor:Unit_Testing}
h1. Unit testing

The unit testing can occur at several levels in your Flowable service unit:
* to check the annotation compliance of the WSDL with the attendees of the component,
* to unit test your XSL generating outputs,
* to unit test your process definition.

A dedicated framework is available as an extension of JUnit providing facilities:
* to validate your WSDL:
** in a WSDL point of view,
** and checking the compliance of the WSDL with the attendees of the component,
* to verify easily the XSL used to generate output replies.

This dedicated framework is provided by the Maven artifact {{org.ow2.petals:petals-se-flowable-junit}}:
{code:xml}
<project>
...
<dependencies>
...
<dependency>
<groupId>org.ow2.petals</groupId>
<artifactId>petals-se-flowable-junit</artifactId>
<version>1.1.1</version>
<scope>test</scope>
</dependency>
...
</dependencies>
...
</project>
{code}

{warning}
See the [Compatibility Matrix|petalsesb:Compatibility Matrix] to known the version of the SE Flowable Junit framework compliant with your version of the SE Flowable.
{warning}

h2. Checking the compliance of the WSDL

The unit test framework contains an assertion '{{assertWsdlCompliance}}' to verify easily the compliance of your WSDL with the attendees of the mode 'service':
{code:lang=java}
import static org.ow2.petals.flowable.junit.Assert.assertWsdlCompliance;
import javax.xml.namespace.QName;
import org.junit.Test;

public class ValidateTest {

@Test
public void validate() throws Exception {
assertWsdlCompliance(new QName[] { new QName("http://petals.ow2.org/samples/se-flowable/vacationService", "new"),
new QName("http://petals.ow2.org/samples/se-flowable/vacationService", "validate"),
new QName("http://petals.ow2.org/samples/se-flowable/vacationService", "update") });
}

}
{code}

See the Javadoc for more details on parameters.

h2. Unit-testing your XSLs

The unit test framework contains an assertion '{{assertXslTransformation}}' to verify easily the result of your XSL transformations:
{code:lang=java}
import static org.ow2.petals.flowable.junit.Assert.assertXslTransformation;
import ...
import org.junit.Test;

public class XslTest {

@Test
public void newVacationRequestResponse_Nominal() throws IOException, TransformerException, SAXException {
assertXslTransformation(NEW_VACATION_RESULT_DIR + "nominal.xml", XSL_NEW_VACATION, "AZE123", null, null, false);
}

}
{code}

See the Javadoc for more details on parameters.

h2. Unit-testing your process definition

Flowable provides a JUnit framework to write unit tests about business processes. You can find several articles on this subject on Internet, for example [here|http://docs.alfresco.com/activiti/topics/apiUnitTesting.html].
We don't discuss how to use the Flowable JUnit framework but how to integrate it into a service unit project.

We provided a JUnit framework inherited from the Flowable one that add several utility methods to simplify checks about our process. These methods are available as member methods of {{PetalsFlowableRule}}:
* awaiting methods ({{wait...}}) as '{{waitEndOfProcessInstance}}' to wait the end of a process instance.
* assertion methods ({{assert...}}) as '{{assertProcessInstanceFinished}}' to check that your process instance is ended.
See the class {{PetalsFlowableRule}} to get the list of methods.

First, you must embedd an Flowable engine for your test, adding an dependency on it with scope {{test}} into your POM file. Don't forget to add also the JDBC driver, H2 for example, and the Petals JUnit Flowable framework:
{code:xml}
<project>
...
<dependencies>
...
<dependency>
<groupId>org.flowable</groupId>
<artifactId>flowable-engine</artifactId>
<version>6.0.1</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.4.178</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.ow2.petals</groupId>
<artifactId>petals-se-flowable-junit</artifactId>
<version>1.0.0</version>
<scope>test</scope>
</dependency>
...
</dependencies>
...
</project>
{code}
{tip}Caution to use the same version of the Flowable engine as the one embedded into the Petals SE Flowable{tip}

Next, your database must be linked to the Flowable engine through a Spring configuration located into the file {{src/test/resources/flowable.cfg.xml}} containing something like:
{code:xml}
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

<bean id="processEngineConfiguration" class="org.flowable.engine.impl.cfg.StandaloneInMemProcessEngineConfiguration">
<property name="jdbcUrl" value="jdbc:h2:mem:flowable;DB_CLOSE_DELAY=1000" />
<property name="jdbcDriver" value="org.h2.Driver" />
<property name="jdbcUsername" value="sa" />
<property name="jdbcPassword" value="" />
</bean>
</beans>
{code}

So, with this, you will be able to test the deployment of your process definition and check process instance creations using the Petals Flowable JUnit framework:
{code:java}
public class ProcessDeploymentTest {

@Rule
public final PetalsFlowableRule flowableRule = new PetalsFlowableRule();

@Test
@Deployment(resources = {"jbi/vacationRequest.bpmn20.xml"})
public void theProcessIsDeployableAndInstanciable() {
final ProcessDefinition processDefinition = this.flowableRule.getRepositoryService()
.createProcessDefinitionQuery().processDefinitionKey("vacationRequest").singleResult();
assertNotNull(processDefinition);

final Map<String, Object> variables = new HashMap<String, Object>();
variables.put("numberOfDays", 10);
variables.put("startDate", new Date());
variables.put("vacationMotivation", "Vacations");
final ProcessInstance processInstance = this.flowableRule.getRuntimeService().startProcessInstanceByKey("vacationRequest", variables);
assertNotNull(processInstance);
}
}
{code}

If your process definition includes Petals service invocations, you must use mocks for these services. These mocks can be SoapUI mock services invoked as standard web-services, using HTTP/SOAP. The URLs of these mock services must be mapped on the endpoint names define in service provider WSDLs used in the process definition. The mapping is declared in the Spring configuration file as following:
{code:xml}
<bean id="archiveEndpoint" class="javax.xml.namespace.QName">
<constructor-arg index="0" value="http://petals.ow2.org/samples/se-flowable/archiveService" />
<constructor-arg index="1" value="autogenerate" />
</bean>

<bean id="notifyEndpoint" class="javax.xml.namespace.QName">
<constructor-arg index="0" value="http://petals.ow2.org/samples/se-flowable/notifyVacationService" />
<constructor-arg index="1" value="autogenerate" />
</bean>

<bean id="wsOverridenEndpointAddresses" class="java.util.concurrent.ConcurrentHashMap">
<constructor-arg index="0">
<map>
<entry>
<key>
<ref bean="archiveEndpoint" />
</key>
<value type="java.net.URL">http://localhost:8188/mockarchiveSoapBinding</value>
</entry>
<entry>
<key>
<ref bean="notifyEndpoint" />
</key>
<value type="java.net.URL">http://localhost:8188/mocknotifyVacationBinding</value>
</entry>
</map>
</constructor-arg>
</bean>

<bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneInMemProcessEngineConfiguration">
...
<property name="wsOverridenEndpointAddresses">
<ref bean="wsOverridenEndpointAddresses" />
</property>
</bean>
{code}

and SoapUI mock services can be automatically started at Maven level with following declaration in the POM file of the service unit:
{code:xml}
