h1. Packaging
As described previously, the plugin supports different packaging to build JBI artifacts.
This section details and illustrates them. As a general matter, defining specific packaging allows to use JBI archives as dependencies in other projects.
It also allows to define the build life cycle to apply on such a project.
{note}
When installing such artifacts in a repository, only the JBI archive is installed.
{note}
h2. jbi-component
This packaging identifies a Maven project as being the development of a JBI component (either a binding component, or a service engine).
The associated language is Java.
The build life cycle of a JBI component is:

h2. Additional jbi resources packaging
For service unit, component, shared library ... you can provided a directory, thank to following xml element _additionalJBIResourceDirectory_, which allows to specify a directory where all contained files will be added to zip archive of the su, sl, component ...
This previous mechanism provide a way to package additional jbi resources into your su, sl, component as in the following example:
{code:lang=xml|title=pom.xml} <build>
<plugins>
<plugin>
<groupId>org.ow2.petals</groupId>
<artifactId>petals-maven-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<additionalJBIResourceDirectory>${project.build.directory}/additionals/</additionalJBIResourceDirectory>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.3</version>
<executions>
<execution>
<id>unpackaging</id>
<phase>process-resources</phase>
<goals>
<goal>unpack</goal>
</goals>
<configuration>
<artifactItems>
<artifactItem>
<groupId>com.ebmwebsourcing.petals-esb-enterprise.usecase1.node2</groupId>
<artifactId>su-filetransfer-P6-provide</artifactId>
<version>0-SNAPSHOT</version>
<type>jbi-service-unit</type>
<overWrite>false</overWrite>
<outputDirectory>${project.build.directory}/additionals/</outputDirectory>
<includes>**/*.wsdl</includes>
<excludes>**/*.class,**/*.jar</excludes>
</artifactItem>
</artifactItems>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>{code}
In the previous example, during the *mvn clean install* of the su-bpel-S9-provide, maven just unpackage the P6.wsdl located in +su-filetransfer-P6-provide+ dependency and copy the wsdl into
{noformat}${project.build.directory}/additionals/ --> corresponding to target/additionals/{noformat}After that the petals-maven-plugin take the P6.wsdl file located into target/additionals precised by the following line:
{noformat}<additionalJBIResourceDirectory>${project.build.directory}/additionals</additionalJBIResourceDirectory>{noformat}
and copy this wsdl file into your _su-bpel-S9-provided.zip_ (it will be copy directly at the root path into zip file)
h1. Goals
As explained in introduction, the Petals plugin for Maven supports several goals.
This section details and illustrates them.
The available goals are:
* *jbi-package*: used to package a JBI archive.
* *jbi-configure*: used to configure a deliverable JBI archive.
h2. jbi-package
This goal allows the creation of a JBI archive.
Depending on the project nature (which is defined by its packaging attribute in the pom.xml), the right archive will be created.
{tip}
For a service assembly project, the service-units that are contained in this assembly must be declared as dependencies in the POM.
{tip}
\\
|| Parameter || Type || Default Value || Packaging || Description ||
| jbiName | String | $\{project.artifactId\}-$\{project.version\} | \* | The file name of the JBI archive (no file path or file extension). |
| verbose | boolean | false | \* | Verbose mode. When activated, information logged at the INFO level are displayed. Information from other levels are always displayed, independently of this mode activation. |
| jbiDirectory | String | $\{basedir\}/src/main/jbi | \* | Path to JBI sources. This path contains the JBI descriptor (jbi.xml). Every file being in this directory will be packaged in the JBI archive under the *META-INF* folder. |
| {anchor:jbi-package-updateJbiXml}updateJBIXml | boolean | true | \* | When true, the packaging updates the JBI descriptor from the project's POM. \\
This option must be activated to configure the JBI archive. |
| isStandardServiceUnit | boolean | false | jbi-service-unit | If the JBI update is activated, this parameter will enable/disable the generation of Petals extensions resulting in a deployable service unit. If *false*, a standard service unit will be generated, otherwise a deployable service unit will be packaged. |
| serviceUnitFileNameMappingInSA | String | $$\{artifactId\}-$$\{version\}.$$\{extension\} | jbi-service-assembly | This parameter makes sense only if the [updateJBIXml|#jbi-package-updateJbiXml] option is activated. \\
It defines the name format of JBI archives for the service-units this assembly embeds. It can be used to make them match the content of the JBI descriptor of the assembly. Maven project properties completed with '{{version.major}}' and '{{version.minor}}' can be used as expression patterns.\\
\\
See [how to escape property resolution|#escaping_dollar] to be able to correctly set value for this parameter. |
| serviceUnitNameMappingInSA | String | $$\{artifactId\}-$$\{version\} | jbi-service-assembly | This parameter makes sense only if the [updateJBIXml|#jbi-package-updateJbiXml] option is activated. \\
It defines the name format (the <name> mark-up) of service-units embedded by the service assembly archive. Maven project properties completed with '{{version.major}}' and '{{version.minor}}' can be used as expression patterns. \\
\\
See [how to escape property resolution|#escaping_dollar] to be able to correctly set value for this parameter. |
| serviceAssemblyNameMapping | String | $$\{artifactId\}-$$\{version\} | jbi-service-assembly | This parameter makes sense only if the [updateJBIXml|#jbi-package-updateJbiXml] option is activated. \\
It defines the format of the service assembly name in the JBI descriptor. Maven project properties completed with '{{version.major}}' and '{{version.minor}}' can be used as expression patterns. \\
\\
See [how to escape property resolution|#escaping_dollar] to be able to correctly set value for this parameter. |
| sharedLibraryNameMappingInComponent | String | $$\{artifactId\} | jbi-component | This parameter makes sense only if the [updateJBIXml|#jbi-package-updateJbiXml] option is activated. \\
When a component depends on a shared library, this last one can be automatically added in the component's JBI descriptor. This parameter defines the name of the shared-libraries to add in the JBI descriptor. Maven project properties completed with '{{version.major}}' and '{{version.minor}}' can be used as expression patterns. \\
\\
See [how to escape property resolution|#escaping_dollar] to be able to correctly set value for this parameter. |
| componentNameMapping | String | $$\{artifactId\} | jbi-component | This parameter makes sense only if the [updateJBIXml|#jbi-package-updateJbiXml] option is activated. \\
This parameter defines the name format of the component in the JBI descriptor. Maven project properties completed with '{{version.major}}' and '{{version.minor}}' can be used as expression patterns. \\
\\
See [how to escape property resolution|#escaping_dollar] to be able to correctly set value for this parameter. |
| sharedLibraryNameMapping | String | $$\{artifactId\} | jbi-shared-library | This parameter makes sense only if the [updateJBIXml|#jbi-package-updateJbiXml] option is activated. \\
This parameter defines the name format of the shared library in the JBI descriptor. Maven project properties completed with '{{version.major}}' and '{{version.minor}}' can be used as expression patterns. \\
\\
See [how to escape property resolution|#escaping_dollar] to be able to correctly set value for this parameter. |
| includeConfiguration \\ | boolean \\ | true \\ | \* \\ | Flag to activate JBI archive configuration when packaging it. To authorize the component configuration when packaging it, JBI descriptor update MUST be activated (see [updateJBIXml|#jbi-package-updateJbiXml]). \\
\\
If one of files needed by the component configuration is missing, no configuration is applied. \\ |
| jbiIdentifiersMappingFile | String | jbi-identifiers-mapping-file.properties | \* \\ | JBI identifiers mapping configuration file. Must be available through the plug-in class-path. \\
Each file line contains a key and a value. The value is used as expression defining the JBI identifier of the artifact matching the key. The key is composed of 4 mandatory fields separated by ":" (caution to use the escape character), each field can contain the value "*" to match any value: \\
# groupId,
# artifactId,
# version,
# packaging: one of jbi-component, jbi-shared-library, jbi-service-unit, jbi-service-assembly. \\
\\
Example, the following mapping rules define that all component identifiers contain the major version part except for the BC Soap:
{code} org.ow2.petals\:petals-bc-soap\:*\:jbi-component = ${artifactId}
*\:*\:*\:jbi-component = ${artifactId}-${version.major}
{code} |
| jbiIdentifiersMappingFileURL | URL | \- \\ | \* \\ | If the JBI shared library list mapping configuration file (jbiSharedLibrariesMappingFile) does not exist through the class-path, the file is look for according to this URL. |
| jbiVersionsMappingFile | String | jbi-versions-mapping-file.properties | \* \\ | JBI versions mapping configuration file. Must be available through the plug-in class-path. \\
Each file line contains a key and a value. The value is used as expression defining the JBI version of the artifact matching the key. The key is composed of 4 mandatory fields separated by ":" (caution to use the escape character), each field can contain the value "*" to match any value: \\
# groupId,
# artifactId,
# version,
# packaging: one of jbi-component, jbi-shared-library, jbi-service-unit, jbi-service-assembly. \\
\\
Example, the following mapping rules define that all shared libraries version identifiers are the major version: \\
{code}
*\:*\:*\:jbi-shared-library = ${version.major}
{code} |
| jbiVersionsMappingFileURL | URL | \- \\ | \* \\ | If the JBI versions mapping configuration file (jbiVersionsMappingFile) does not exist through the class-path, the file is look for according to this URL. |
| toExcludes | String | \- \\ | jbi-component \\
jbi-shared-library \\ | This parameter makes sense only if the [updateJBIXml\|#jbi-package-updateJbiXml] option is activated. It contains a list a JAR files (comma separated) to exclude from the packaging. \\ |
| downloadAndPackageWsdlResources | boolean | false | jbi-service-unit | If true, imports used in the WSDL of an SU will be resolved and packaged inside the service unit JBI archive. |
| attachJar | boolean | false | \* | If true, the jar will be installed and deployed alongside the JBI component's zip into Maven repositories. |
h3. How is updated the JBI descriptor ?
As explain below, the parameter [updateJBIXml|#jbi-package-updateJbiXml] is used to generated the JBI descriptor from the Maven POM file. Updates are done according to the nature of the JBI archive and following rules.
h4. JBI descriptor updates of a component archive
|| JBI descriptor node \\ || Source of the value \\ ||
| jbi/component/identification/name | The value is controlled by the parameter 'componentNameMapping' and identification values defined in the POM file of the component project. Can be overridden by the content of the configuration parameters if artifact configuration is enabled (includeConfiguration). \\ |
| jbi/component/identification/description | The value is the content of the tag <description> of the POM file, if not null. Otherwise the initial value is kept. \\ |
| jbi/component/component-class-path | Contains all dependencies resolved by Maven. Transitive dependencies of shared-library are not included. \\
Initial content is kept, even if not contained in the dependencies resolved by Maven. \\ |
| jbi/component/bootstrap-class-path | Same as jbi/component/component-class-path |
| jbi/component/shared-library | If the configuration mode is enabled (includeConfiguration): \\
* a tag <shared-library> is created for each shared library declared in:
** the configuration files (jbiSharedLibrariesMappingFile or jbiSharedLibrariesMappingFileURL), if they exist.
** otherwise, in the project POM file. shared library must be declared as a provided dependency with type set to 'jbi-shared-library'.
* If an identifier mapping is defined (see jbiIdentifiersMappingFile or jbiIdentifiersMappingFileURL) for the shared library, the resulting identifier is used as JBI identifier. Otherwise, it will be defined by the parameter 'sharedLibraryNameMappingInComponent'.
* If a version mapping configuration exists (jbiVersionsMappingFile or jbiVersionsMappingFileURL) for the shared library, the resulting value is used as version attribute of the shared library. Otherwise, the version defined into the POM is used. |
h4. JBI descriptor updates of a service unit
|| JBI descriptor node \\ || Source of the value \\ ||
| jbi/services/consumes/\* | Each placeholder as $\{my_variable} is replaced by the value of the property, defined in the POM, that as the same name. \\ |

| jbi/service-assembly/service-unit/target/component-name | Content of the tag jbi/component/identification/name of the JBI descriptor of the component on which the service unit must be deployed. It's needed that the component is declared as dependency into the service unit project. Can be overridden by the content of the configuration parameters if artifact configuration is enabled (includeConfiguration). |
h4. JBI descriptor updates of a shared library
{tip}If there is no jbi.xml file present in the source tree, petals-maven-plugin will generate one by itself based on the dependencies declared in the pom.xml{tip}

{anchor:escaping_dollar}
h3. How to escape "$" to avoid property resolution ?
For some parameters it is needed to set value as: "{{$$\{artifactId\}-$$\{version\}}}", and associated properties must not be resolved. The sign "{{$}}" must be escaped as following in the POM file:
{code}
<properties>
<dollar>$</dollar>
</properties>
<build>
<plugins>
<plugin>
<groupId>org.ow2.petals</groupId>
<artifactId>petals-maven-plugin</artifactId>
<configuration>
<serviceUnitNameMappingInSA>${dollar}${dollar}{artifactId}-${dollar}${dollar}{version}</serviceUnitNameMappingInSA>
</configuration>
</plugin>
</plugins>
</build>
{code}
h2. jbi-configure
This goal allows the configuration of a JBI archive. Depending on the JBI archive nature (which is defined by its packaging attribute), the right configuration archive will be applied. Only deliverable JBI archives (component, service assembly and shared library) can be configured by this goal, ie. service unit archive is excluded. The main use-case is the configuration of a JBI archive delivered by a provider.
{tip}
Configuration of a service assembly, ans its service units, is not implemented yet.
{tip}
h3. Use-case example
{note}
Since the version 2.4.0 of the Maven Petals Plugin, no more dummy POM file is required to run following usecases on command line.
But, to run them using a configuration packaged as Maven artifact (org.foo.bar:configuration:1.0.0), it is needed to have the following dummy POM file:
{code:language=xml|theme=Eclipse}
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

h4. Use-case 1 : How to set a JMS driver into a component
For example, we wish, on the same JBI container:
* to use the ActiveMQ v4.1.1 as JMS server and the BC JMS to interact with Petals ESB through JMS messages. So the BC JMS needs the shared library associated to its ActiveMQ server version.
* to use the ActiveMQ v5.2.0 as JMS server and the BC Soap to interact with Petals ESB through SOAP over JMS. So the BC Soap needs the shared library associated to its ActiveMQ server version.
In one hand, we need to deploy these shared libraries on the JBI container. So, each shared library MUST have a different JBI identifier name, for example petals-sl-jms-activemq-4 et petals-sl-jms-activemq-5.
In other hand, we don't want to change the content of the component JBI descriptor when upgrading a shared library because of bug fixes. So, we can you use the major digit of the version as version attribute for shared library identifier.
So, we need to inject this JBI identifier name and version attribute of the shared libraries in the JBI components:
* First, we configure the shared libraries using the goal 'jbi-configure':
{code}
mvn org.ow2.petals:petals-maven-plugin:2.4.0:jbi-configure -DgroupId=org.ow2.petals -DartifactId=petals-sl-jms-activemq -Dversion=4.1.1 -DjbiIdentifiersMappingFileURL=http://myhost:myport/myPath/jbi-identifiers-mapping-file.properties
mvn org.ow2.petals:petals-maven-plugin:2.4.0:jbi-configure -DgroupId=org.ow2.petals -DartifactId=petals-sl-jms-activemq -Dversion=5.2.0 -DjbiIdentifiersMappingFileURL=http://myhost:myport/myPath/jbi-identifiers-mapping-file.properties
{code}
* Next, we configure the components:
{code}
mvn org.ow2.petals:petals-maven-plugin:2.4.0:jbi-configure -DgroupId=org.ow2.petals -DartifactId=petals-bc-jms -Dversion=3.1.1 -DjbiIdentifiersMappingFileURL=http://myhost:myport/myPath/jbi-identifiers-mapping-file.properties -DjbiSharedLibrariesMappingFileURL=http://myhost:myport/myPath/jbi-shared-libraries-list-mapping-file.properties -DjbiVersionsMappingFileURL=http://myhost:myport/myPath/jbi-versions-mapping-file.properties
mvn org.ow2.petals:petals-maven-plugin:2.4.0:jbi-configure -DgroupId=org.ow2.petals -DartifactId=petals-bc-soap -Dversion=4.0.2 -DjbiIdentifiersMappingFileURL=http://myhost:myport/myPath/jbi-identifiers-mapping-file.properties -DjbiSharedLibrariesMappingFileURL=http://myhost:myport/myPath/jbi-shared-libraries-list-mapping-file.properties -DjbiVersionsMappingFileURL=http://myhost:myport/myPath/jbi-versions-mapping-file.properties
{code}
* using the following content of the file 'jbi-identifiers-mapping-file.properties':
{code}
*\:*\:*\:jbi-component = ${artifactId}-${version.major}
*\:*\:*\:jbi-shared-library = ${artifactId}-${version.major}
*\:*\:*\:jbi-service-unit = ${artifactId}-${version}
*\:*\:*\:jbi-service-assembly = ${artifactId}-${version}
{code}
* using the following content of the file 'jbi-shared-libraries-list-mapping-file.properties':
{code}
org.ow2.petals\:petals-bc-jms\:*\:1 = org.ow2.petals:petals-sl-jms-activemq:4.1.1
org.ow2.petals\:petals-bc-soap\:*\:1 = org.ow2.petals:petals-sl-jms-activemq:5.2.0
{code}
* using the following content of the file 'jbi-versions-mapping-file.properties':
{code}
*\:*\:*\:jbi-shared-library = ${version.major}
{code}
h4. Use-case 2 : How to package an interceptor
The Petals CDK proposes some extension points to add specific processing. These points are named 'interceptors'. An interceptor must be packaged into the JBI component archive. This packaging can be done by the goal 'jbi-configure'.
For example, we wish to package our interceptor, available as a Maven artifact: org.ow2.petals.samples:my-interceptor:1.0.0:jar, into the BC Soap. So we will configure the BC Soap with an extra class-path element (our interceptor). And, as our interceptor is only needed to the component runtime, not to the component bootstrap, we will use the following command line:
{code}
mvn org.ow2.petals:petals-maven-plugin:2.4.0:jbi-configure -DgroupId=org.ow2.petals -DartifactId=petals-bc-soap -Dversion=4.0.2 -DjbiExtraComponentClasspathMappingURL=file:///home/myuser/my-extra-component-classpath-mapping.properties
{code}
where the file /home/myuser/my-extra-component-classpath-mapping.properties contains:
{code}
org.ow2.petals\:petals-bc-soap\:*\:1=org.ow2.petals.samples\:my-interceptor\:1.0.0
{code}
You can enable or disable a interceptor using the configuration file associated to the parameter {{componentInterceptorCustomizationFile}} of the goal jbi-configure. The following configuration will configure the interceptors of the component {{petals-bc-soap}}: The interceptor {{MyCustomInterceptorNameNotActivated}} is disable, the interceptor {{MyCustomInterceptorNameActivated}} is enabled with a dedicated parameter.
{code}
org.ow2.petals\:petals-bc-soap\:1 = foo.bar.MyInterceptor:MyCustomInterceptorNameNotActivated:false
org.ow2.petals\:petals-bc-soap\:2 = foo.bar.My2ndInterceptor:MyCustomInterceptorNameActivated:true:paramName1:paramValue1
{code}
h4. Use-case 3 : How to configure a service unit to use an interceptor
An interceptor must be configured to be executed on needed phases: {{accept}}, {{accept-response}}, {{send}} and {{send-response}} associated to the message exchanges.
Such a configuration can be updated directly from the service assembly containing service units without to restart a development cycle. Just use the goal 'jbi-configure' as following:
{code}
mvn org.ow2.petals:petals-maven-plugin:2.4.0:jbi-configure -DgroupId=org.ow2.petals.samples -DartifactId=interceptor-sa -Dversion=1.0.0 -DserviceInterceptorCustomizationFileURL=file:///home/myuser/service-interceptors-customization.properties -DserviceInterceptionConfigurationName=productionConfiguration
{code}
where:
* {{org.ow2.petals.samples:interceptor-sa:1.0.0}} is the service assembly containing service units to configure,
* {{serviceInterceptorCustomizationFileURL}} specifies a file containing the configurations of interceptors to apply,
* {{serviceInterceptionConfigurationName}} defines the interceptor configuration to apply
The service interceptor customization file contains something like that:
{code}
productionConfiguration\:provider\:*\:*\:*\:accept\:1 = MyCustomInterceptorName:paramName1:paramValue1:paramName2:paramValue2
productionConfiguration\:provider\:*\:*\:*\:accept-response\:1 = MyCustomInterceptorName:paramName1:paramValue1:paramName2:paramValue2

h4. Use-case 4 : How to install the same component in two different versions on the same container
For example, we wish, on the same JBI container:
* to use the BC Soap version 3.1.4 to connect old service assemblies,
* to use the BC Soap version 4.0.5 to use the last functions provided by the BC Soap.
This needs different JBI identifier in each component. So we can suffix the JBI identifier with the major digit of the version two create different identifiers for each component:
{code}
mvn org.ow2.petals:petals-maven-plugin:2.4.0:jbi-configure -DgroupId=org.ow2.petals -DartifactId=petals-bc-soap -Dversion=3.1.4 -DjbiIdentifiersMappingFileURL=http://myhost:myport/myPath/jbi-identifiers-mapping-file.properties
mvn org.ow2.petals:petals-maven-plugin:2.4.0:jbi-configure -DgroupId=org.ow2.petals -DartifactId=petals-bc-soap -Dversion=4.0.5 -DjbiIdentifiersMappingFileURL=http://myhost:myport/myPath/jbi-identifiers-mapping-file.properties
{code}
using the following content of the file 'jbi-identifiers-mapping-file.properties':
{code}
*\:*\:*\:jbi-component = ${artifactId}-${version.major}
*\:*\:*\:jbi-shared-library = ${artifactId}-${version.major}
*\:*\:*\:jbi-service-unit = ${artifactId}-${version}
*\:*\:*\:jbi-service-assembly = ${artifactId}-${version}
{code}
{tip}
To use a configuration available as Maven artifact, use the following command line:
{code}
mvn org.ow2.petals:petals-maven-plugin:2.4.0:jbi-configure -DgroupId=org.ow2.petals -DartifactId=petals-bc-soap -Dversion=3.1.4 -DjbiIdentifiersMappingFile=jbi-identifiers-mapping-file.properties
{code}
where jbi-identifiers-mapping-file.properties is available as resource into the configuration Maven artifact.
{tip}
{tip}
Don't forget to configure your service assemblies to be able to deploy them on the right component identified by the right JBI identifier.
