h1. Abstract

This component implements "WS-Notification", as described in the set of [OASIS Specifications named "Ws-BrokeredNotification"|http://www.oasis-open.org/committees/wsn/].

Services provided by the petals-se-notification component are  mainly those described in  specification. It means that the petals-se-notification acts a broker - as described
in "WS-BorkeredNotification" specification.It receives "Subscribe" requests respect to defined topics from Notification Consumer and it receives also "RegisterPublisher" requests on some topics from notification Publisher/Producer. Then it receives some "Notify" request from registred Notification producers and forwards these requests to Notification consumers that have previously subscribed on related topics.

h1. Features

The "WS-Notification" features currently available are:

* Processing of "RegisterPublisher" requests (as described in "WS-BrokeredNotification")
* Processing of "DestroyRegistration" requests (as described in "WS-BrokeredNotification")
* Processing of "Subscribe" requests (as described in "WS-BaseNotification")
* Processing of "Unsubscribe" requests (as described in "WS-BaseNotification")
* Processing of "Notify" requests (as described in "WS-BaseNotification")
* Processing of "Renew" requests (as described in "WS-BaseNotification" - Not fully implemented)
* Processing of "GetCurrentMessage" requests (as described in "WS-BaseNotification")
* Processing of "GetSupportedTopics" requests. This operation is not described in WS-Notification specification even if these specifications introduce the need for a service that provides a full description of Topics currently supported by a "WS-Notification producer".

{column}

The "WS-Notification" specification does not fully describe all mechanism infered by the ws-notificatio paradigm and lets us some several implmentation choices respect to concernes like "how notification message are "linked" to topics or "how a Broker can know who ar the producer". This last point - aka "publishing" pattern in the "WS-BrokeredNotification" (page 12/43) - needs some words about our implementation of the in petals ESB. In our implementation choice of the "demand-base" pattern, all subscribe requests send to the broker - the petals-se-notification component \-, from consumers, will be forwarded by the broker to known producers registered on related topics. That arbitrary choice have been made in order to give to consumers a means to "drive" the "eventing communication" by choising the format of the notification message they want to receive.

h1. Component Configuration

The component configuration is mainly defined by its "supported topics set". The "supported topics set" is defined in an xml file whose associated xml schema is the "TopicSet" xml type defined in "WS-Topic" Specification.

{note}keep in mind that topics name and topics namespace are buisness logic dependent
{note}
An exemple of "supported topics set" xml file is provided below:

{code}<xml version="1.0" encoding="UTF-8">

  </childTopic2>
</externalns:rootTopic2>
<wstop:TopicSet> {code}
A default "supported topics set" xml file is defined and embedded in the component. This file will be used to configure topics supported by the petals-se-component unless you define your own one and set the System Environment variable "SUPPORTED_TOPICS_SET" to \[petalsesb:path_to_supported_topics_set_xml_file\]. On "Unix like" operating system, in the console window from where you intend to launch petals ESB and before starting it, do something like:

{code}"export SUPPORTED_TOPICS_SET=path_to_your_supported_topic_set_xml_file"{code}&nbsp;&nbsp;&nbsp;
&nbsp; As shortly described in the previous chapter, an operation called "getSupportedTopics" has been implmented to know which topics any "WS-Notification" concumer can subscribe on and/or "WS-Notification producer" can register to. Have a look the component.wsdl file provided in the annexes of this document for more details.

h1. Component installation

Actually, the component petals-se-notification does not requiered any service units to be configured. The only rule is that it must be deployed and started before any other component that intends to use petals ESB WS-Notification features.


h2. Installation process using Petals ESB Webconsole

If you use to run the webconsole, you must know how to do to install the service engine component. If not, well have a look to the petals ESB Webconsole documentation and simply follow the instructions. The petals-se-notification component does not require any specific actions. You just have to install it before any other component that would use Ws-notification features.

{center}1. Webconsole Component administration page of Petals ESB{center}

h2. "By hand" installation process

If you do not want to use the webconsole, you can install a petals ESB component, in "command line mode". To do tahat you simply have to copy and paste the "petals-se-notification-X.X.zip" zip archive of the component in the sub-folder of your petals ESB platform called "install/". Then, few seconds later, the embedded petals ESB autoloader mechanism will deploy and start the component. This mechanism is enabled in the default configuration of the bus.

{note}Note: To remove "by hand" an installed petals ESB component and/or its service assembly, you simply have to remove the related archive from the "Installed/" folder{note}

h1. Petals ESB "WS-Notification" usecases

h2. Desciption

A demonstation of Petals ESB feature is provided through basic use-cases

Basic WS-Notification usecases consist on sending "notification" requests - Subscribe, Unsubscribe, RegisterPublisher, DestroyRegistration or Notify requests - to the petals-se-notification component from other components that acts as Notification consumer or Notification Producer. Two components named petals-se-Wsnconsumer and petals-se-WsnProducer are available on Petals website under the [Download/tool section|http://petals.ow2.org/download-tools.html]

{note}Note: these two components are only "template component" and can help you to implement your own ones.{note}

h2. Requirements

Basic WS-Notification usecases require that you download and deploy additionnal components:

* *petals-se-WsnConsumer*: service engine component that acts as a Notification Consumer. As soon as its related service assembly is deployed and started, it sends a "Subscribe" request to the Broker (the petas-se-notification that must have been previously deployed). An "unsusbcribe" request is sent when its service assembly is stopped.
* *petals-se-WsnProducer*: service engine component that acts as a Notification Producer. As soon as its related service assembly is deployed and started, it sends a "RegisterPublisher" request to the Broker (the petals-se-notification that must have been previously deployed). An "DestroyRegistration" request is sent when its service assembly is stopped. When the component is registred, it can recieve "Subscribe" request from the "Broker" as described in the "demand-based" publishing pattern (see page 13/43 of the "WS-Brokerednotification" specification)
* *petals-se-rmi*: service engine component use to send notification requests from The webconsole (test page). This component is only required if you expect to test directly the petals-se-notification from the Petals ESB webconsole.These service engines components do not required any specific configuration. You just have to set, in its jbi.xml config file, the parameter "petalsCDK:notifications" to "false" (see the "Petals CDK documentation" for more details)

h2. Running WS-Notification usecases

You can test Petals ESB WS-Notification features using the webconsole test section or you can deploy and start petals-se-Wsn Producer/Consumer components that will automatically process Notification Requests("Subscribe" and "RegisterPublisher requests on start;"Notify" request each 30 seconds) when their services assemblies are deployed and started.

h3. using petals-se-WsnProducer, petals-se-WsnConsumer components

Installing petals-se-WsnProducer and petals-se-WsnConsumer components and their service assemblies will automatically launch usecases. No interactions are needed. On Service assembly start, the&nbsp; petals-se-WsnProducer sends a RegisterPublisher request to the petals-se-notification and the petals-se-WsnConsumer do the same by sending a "Subscribe" request to the petals-se-notification component. Its Subscribe request is then forwarded to the petals-se-WsnProducer as soon as the petals-se-WsnProducer is registered.
To run the usecase you must:

* *{_}Step 1{_}*: Start petals ESB platform. Under Unix like env use command
{code}
$./startup.sh -C
{code}

!start_petals_esb.png|align=center|title=Petals ESB starting message|alt=Petals ESB starting message!
{center}picture-3: Petals ESB started \!{center}

* *{_}Step 2{_}*: Install petals-se-notification component (copy the "petals-se-notification" zip archive in "install/" folder)

!start_petals_se_notif.png|align=center|title=Starting Petals SE Notification component|alt=Starting Petals SE Notification component!
{center}4. Component petals-se-notification started{center}

* *{_}Step 3{_}*: Install petals-se-WsnConsumer component and its service assembly "sa-se-wsnconsumer" (copy related zip archives in "install/" folder). As soon as the service assembly is started, a "Subscribe" request is sent.

{center}6. petals-se-WsnProducer started{center}

Until the petals-se-WsnConsumer send "Unsubscribe" request, the petals-se-WsnProducer will send a Notification message - Notify request - each 30 second to the petals-se-notification.

{center}7. petals-se-WsnProducer generate notifications{center}

h3. using "test section" of the webconsole

You can also test Petals ESB features using the webconsole. To do that you must install petals-se-notification and petals-se-rmi component:

!rmi_and_notif_on_webconsole.png|align=center|title=View installed components through Petals Webconsole admin panel|alt=View installed components through Petals Webconsole admin panel!
{center}8. Web console admin shows installed components{center}

Then to interact with petals-se-notification component, go to "Test" page:

!webconsole_test_page.png|align=center|title=Using Petals Webconsole testing features|alt=Using Petals Webconsole testing features!
{center}9. Web console testing page{center}

Select the endpoint respect to what Request you want to perform:

* *{_}NotificationBrokerServiceEndpoint{_}*: Select this endpoint if you want to perform "RegisterPublisher", "Subscribe" or "Notify" requests.
{note}Set the MEP field value to "InOut", unless you intend to perforn a Notify request that requires InOnly MEP value. Some Notification Payload templates are provided in the annexes chapter to complete the content Test field of the Page test. To see Notify result in Petals console, you must change Petals logger configuration: uncomment the line \{logger.Petals.Container.Components.level DEBUG} in loggers.properties file of petals "conf/" folder{note}

* *{_}SubscriptionManagerServiceEndpoint{_}*: Select this endpoint if you want to perform "Unsubscribe" requests.
