Enabling JMS Transport in WSO2 BPS

As I highlighted in my previous blog post, WSO2 BPS is a powerful open source BPEL engine.Here i am going to enable JMS Transport in WSO2 BPS.  You can use any JMS provider as you preferred. I'm going to use Apache ActiveMQ-5.2.0 for this example.


1. You can download WSO2BPS (version 1.1.1) from here. then you can extract in to a directory in your file system. Lets call as BPS_HOME

2. Start ActiveMQ message broker. Go to (ActiveMQ_Install_directory)/bin and run activemq.sh (or activemq.bin in DOS)

3. Copy ActiveMQ libraries to BPS_HOME/repository/components/lib directory

activemq-core-5.2.0.jar and geronimo-j2ee-management_1.0_spec-1.0

4. Enable JMS Transport in WSO2 BPS.  Uncomment following parameters in axis2.xml (BPS_HOME/conf directory) Here I have configured it for ActiveMQ environment.

For Receiver

<parameter name="myTopicConnectionFactory">
            <parameter name="java.naming.factory.initial">org.apache.activemq.jndi.ActiveMQInitialContextFactory</parameter>
            <parameter name="java.naming.provider.url">tcp://localhost:61616</parameter>
            <parameter name="transport.jms.ConnectionFactoryJNDIName">TopicConnectionFactory</parameter>
        </parameter>


        <parameter name="myQueueConnectionFactory">
            <parameter name="java.naming.factory.initial">org.apache.activemq.jndi.ActiveMQInitialContextFactory</parameter>
            <parameter name="java.naming.provider.url">tcp://localhost:61616</parameter>
            <parameter name="transport.jms.ConnectionFactoryJNDIName">QueueConnectionFactory</parameter>
        </parameter>


        <parameter name="default">
            <parameter name="java.naming.factory.initial">org.apache.activemq.jndi.ActiveMQInitialContextFactory</parameter>
            <parameter name="java.naming.provider.url">tcp://localhost:61616</parameter>
            <parameter name="transport.jms.ConnectionFactoryJNDIName">QueueConnectionFactory</parameter>
        </parameter>

For Sender
    <transportSender name="jms"
                     class="org.apache.axis2.transport.jms.JMSSender"/>

5. Start BPS server running  the wso2server.sh (in unix) or wso2server.bat (in windows)
You can see following Logs when starting if you have correctly configured

[2010-05-27 22:19:55,019]  INFO -  JMS ConnectionFactory : default initialized
[2010-05-27 22:19:55,021]  INFO -  JMS ConnectionFactory : myTopicConnectionFactory initialized
[2010-05-27 22:19:55,022]  INFO -  JMS ConnectionFactory : myQueueConnectionFactory initialized
[2010-05-27 22:19:55,022]  INFO -  JMS Transport Receiver/Listener initialized...

We can see JMS endpoint has been added to BPEL service (See the wsdl also)


Note:-

Step 4,   You can enable JMS and configure it using UI.




But there are some issues when disabling  JMS from UI. So i recommended to use axis2.xml configure JMS in WSO2BPS version 1.1.1. This will be fixed in next WSO2BPS release.....!!!
