WSO2 EI as Both a JMS Producer and Consumer

This section describes how to configure WSO2 Enterprise Integrator (WSO2 EI) to work as a JMS-to-JMS proxy service.

Open

Follow the steps below to configure WSO2 EI to  listen to a JMS queue and consume messages and then send those messages to another JMS queue.

1. Configure WSO2 EI with Apache ActiveMQ and set up the JMS listener and sender. For instructions, see Configure with ActiveMQ.
   

2. Create a proxy service with the following configuration.To create a proxy service using Tooling, see Working with Proxy Services via Tooling.

   <proxy name="StockQuoteProxy" transports="jms"> <target> <inSequence> <property action="set" name="OUT_ONLY" value="true"/> <send> <endpoint> <address uri="jms:/SimpleStockQuoteService?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory& java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory&java.naming.provider.url=tcp://localhost:61616"/> </endpoint> </send> </inSequence> </target> </proxy>

3. To place a message into a JMS queue, execute following command from <EI_HOME>/samples/axis2Client directory.

Generally, JMS is used for one-way, asynchronous message exchange. However you can perform synchronous messaging also with JMS. For more information, see JMS Synchronous Invocations : Dual Channel HTTP-to-JMS and JMS Synchronous Invocations : Quad Channel JMS-to-JMS.
