If your system has more than one existing brokers, it will be required to configure the JMS transport with multiple brokers. In such situations, each transport receiver should have a separate name. 

The following example illustrates how to configure the WSO2 ESB to listen to both ActiveMQ and WSO2 MB messages.

  1. Download ActiveMQ (version 5.8.0 or later) from the Apache ActiveMQ site. Download the WSO2 Message Broker from the WSO2 Message Broker site.
  2. Copy the following client libraries from <AMQ_HOME>/lib directory to <ESB_HOME>/repository/components/lib directory.
    • activemq-broker-5.8.0.jar 
    • activemq-client-5.8.0.jar 
    • geronimo-jms_1.1_spec-1.1.1.jar 
    • geronimo-j2ee-management_1.1_spec-1.0.1.jar 
    • hawtbuf-1.9.jar 
  3. Copy the andes-client-0.13.wso2v10.jar from <MB_HOME>/client-lib directory to <ESB_HOME>/repository/components/lib directory.
  4. Configure the <ESB_HOME>/repository/conf/axis2/axis2.xml file as follows to enable ActiveMQ as a transport listener.

    <transportReceiver name="jms1" class="org.apache.axis2.transport.jms.JMSListener">
           <parameter name="myTopicConnectionFactory" locked="false">
               <parameter name="java.naming.factory.initial" locked="false">org.apache.activemq.jndi.ActiveMQInitialContextFactory</parameter>
               <parameter name="java.naming.provider.url" locked="false">tcp://localhost:61616</parameter>
               <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">TopicConnectionFactory</parameter>
                <parameter name="transport.jms.ConnectionFactoryType" locked="false">topic</parameter>
           </parameter>
     
           <parameter name="myQueueConnectionFactory" locked="false">
               <parameter name="java.naming.factory.initial" locked="false">org.apache.activemq.jndi.ActiveMQInitialContextFactory</parameter>
               <parameter name="java.naming.provider.url" locked="false">tcp://localhost:61616</parameter>
               <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">QueueConnectionFactory</parameter>
                <parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
           </parameter>
     
           <parameter name="default" locked="false">
               <parameter name="java.naming.factory.initial" locked="false">org.apache.activemq.jndi.ActiveMQInitialContextFactory</parameter>
               <parameter name="java.naming.provider.url" locked="false">tcp://localhost:61616</parameter>
               <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">QueueConnectionFactory</parameter>
                <parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
           </parameter>
       </transportReceiver>

    Enter the following configuration in the same file to enable the WSO2 Message Broker.

    <!--Uncomment this and configure as appropriate for JMS transport support with WSO2 MB 2.x.x -->
       <transportReceiver name="jms2" class="org.apache.axis2.transport.jms.JMSListener">
           <parameter name="myTopicConnectionFactory" locked="false">
              <parameter name="java.naming.factory.initial" locked="false">org.wso2.andes.jndi.PropertiesFileInitialContextFactory</parameter>
               <parameter name="java.naming.provider.url" locked="false">repository/conf/jndi.properties</parameter>
               <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">TopicConnectionFactory</parameter>
               <parameter name="transport.jms.ConnectionFactoryType" locked="false">topic</parameter>
           </parameter>
     
           <parameter name="myQueueConnectionFactory" locked="false">
               <parameter name="java.naming.factory.initial" locked="false">org.wso2.andes.jndi.PropertiesFileInitialContextFactory</parameter>
               <parameter name="java.naming.provider.url" locked="false">repository/conf/jndi.properties</parameter>
               <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">QueueConnectionFactory</parameter>
              <parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
           </parameter>
     
           <parameter name="default" locked="false">
               <parameter name="java.naming.factory.initial" locked="false">org.wso2.andes.jndi.PropertiesFileInitialContextFactory</parameter>
               <parameter name="java.naming.provider.url" locked="false">repository/conf/jndi.properties</parameter>
               <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">QueueConnectionFactory</parameter>
               <parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
           </parameter>
       </transportReceiver>

    Note that the transport receiver name is different in each configuration.

  5. Add a topic and a queue to the  jndi.properties file located in <ESB_HOME>/repository/conf as follows:

    <connection-factory name="QueueConnectionFactory">
          <xa>false</xa>
          <connectors>
             <connector-ref connector-name="netty"/>
          </connectors>
          <entries>
             <entry name="/QueueConnectionFactory"/>
          </entries>
    </connection-factory>
    
    
    <connection-factory name="TopicConnectionFactory">
          <xa>false</xa>
          <connectors>
             <connector-ref connector-name="netty"/>
          </connectors>
          <entries>
             <entry name="/TopicConnectionFactory"/>
          </entries>
    </connection-factory>
  6. Start both ActiveMQ and WSO2 MB.
  7. Start the WSO2 ESB server and the management console. If they are already running, restart them.

Now a proxy service can be created with reference to transport receiver JMS1 and/or JMS2. For example, the following proxy service is configured with reference to both transport receivers.

<proxy xmlns="http://ws.apache.org/ns/synapse" 
name="jmsMultipleListnerProxy" 
transports="jms1,jms2" 
statistics="disable" 
trace="disable" 
startOnLoad="true"> 
<target> 
<inSequence> 
<log level="full"/> 
<send> 
<endpoint> 
<address uri="http://localhost:9000/services/SimpleStockQuoteService"/> 
</endpoint> 
</send> 
</inSequence> 
<outSequence> 
<send/> 
</outSequence> 
</target> 
<parameter name="transport.jms.ContentType"> 
<rules> 
<jmsProperty>contentType</jmsProperty> 
<default>application/xml</default> 
</rules> 
</parameter> 
<description/> 
</proxy>
