1. Download and install WSO2 MB according to the instructions in the Getting Started.  

It is not possible to start multiple WSO2 products with their default configurations simultaneously in the same environment. Since all WSO2 products use the same port in their default configuration, there will be port conflicts. Therefore, to avoid port conflicts, apply a port offset in <MB_HOME>/repository/conf/carbon.xml file by changing the offset value to 1. For example,

...

1. Download and install WSO2 AS binary distribution. Instructions can be found in the 'Installation Guide' of the respective AS documentation version. For example, Installation Guide.   The unzipped AS distribution folder is referred to as AS_HOME.

2. WSO2 AS doesn't come with a default enabled JMS transport configuration to communicate with the Message Broker. Therefore we need to add a <transport receiver> block for MB 2.x.x by editing the $AS_HOME/repository/conf/axis2/axis2.xml file as follows.

...

<!-- uncomment this and configure to use connection pools for sending messages>
<transportSender name="jms" class="org.apache.axis2.transport.jms.JMSSender"/-->

...

4. Then add the following ' jndi.properties ' into $AS_HOME/repository/conf/ directory in order to point to the running Message Broker.

# register some connection factories
# connectionfactory.[jndiname] = [ConnectionURL]
connectionfactory.QueueConnectionFactory = amqp://admin:admin@clientID/carbon?brokerlist='tcp://localhost:5673'
connectionfactory.TopicConnectionFactory = amqp://admin:admin@clientID/carbon?brokerlist='tcp://localhost:5673'
# register some queues in JNDI using the form
# queue.[jndiName] = [physicalName]
queue.SimpleEventSinkService = SimpleEventSinkService

# register some topics in JNDI using the form
# topic.[jndiName] = [physicalName]

In this file add the names of the queues or topics that needs to be created in the Message Broker, for the corresponding service in the App Server. For example, if the deployed service which needs to subscribe to a queue in MB is named SimpleEventSinkService, add a queue named 'SimpleEventSinkService' into the jndi.properties file as shown above. When there are messages published to 'SimpleEventSinkService' queue in MB, the SimpleEventSinkService in App Server will receive them and process accordingly.

5. Copy the following jar files from <MB_HOME>/client-lib folder to <AS_HOME>/repository/components/lib folder. They are client libraries required from Message Broker to AS.

6. Once the JMS transport is enabled for App Server, it will reflect in all the services deployed in App Server and this can cause an unexpected error while the server start starts up. Message Broker handles this for axis2 services by using dynamic queue/topic support, however the REST, JS services deployed in App Server still needs to be explicitly configured. Therefore, edit and add the following parameters into $<AS_HOME>/repository/deployment/server/servicemetafiles/admin/RESTSample.xml file. Make sure the exposedAllTransports parameter is set to 'false'.

This section describes, through a usecase, how to integrate WSO2 Message Broker for using a WSO2 AS web service as a JMS subscriber.

Usecase

Deploy a sample web service in App Server which listens on SOAP messages and print the message string into console. Then a A JMS queue for with the name of this service will be generated in the Message Broker. Publish a message to this queue and it will be received and printed into the App Server console by the sample web service.

1. Log into App Server and upload SimpleEventSinkService.aar archive which can be downloaded from here, by selecting 'Home --> Manager --> Services --> Add --> AAR Service'.
2. Log into Message Broker and publish a text message into the created SimpleEventSinkService queue using the message sender UI.

...

3. Go to the App Server terminal back and the published message will be displayed in the console as, 'Got the message ==> Test Message'.
