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

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

   Code Block
   language xml
   <proxy xmlns="http://ws.apache.org/ns/synapse" name="JMStoHTTPStockQuoteProxy" transports="jms"> <target> <inSequence> <property action="set" name="OUT_ONLY" value="true"/> </inSequence> <endpoint> <address uri="http://localhost:9000/services/SimpleStockQuoteService"/> </endpoint> <outSequence> <send/> </outSequence> </target> </proxy>

   Tip

   You can make the proxy service a JMS listener by setting its transport as jms. Once the JMS transport is enabled for a proxy service, ESB will start listening on a JMS queue with the same name as the proxy service. In the sample configuration above,  ESB listens to a JMS queue named JMStoHTTPStockQuoteProxy. To make the proxy service listen to a different JMS queue, define the transport.jms.Destination parameter with the name of the destination queue.

3. To test this you will need an HTTP back-end service. Deploy the SimpleStockQuoteService and start the Axis2 server. 

4. Place a message into the Apache ActiveMQ queue by executing the following command from <ESB_HOME>/samples/axis2Client folder.

   Code Block
   language xml
   ant stockquote -Dmode=placeorder -Dtrpurl="jms:/JMStoHTTPStockQuoteProxy?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory&java.naming.provider.url=tcp://localhost:61616&transport.jms.ContentTypeProperty=Content-Type&transport.jms.DestinationType=queue"
