Objective: Demonstrate one way message bridging from JMS to HTTP using inbound JMS endpoint.

Prerequisites
  • Start the Axis2 server and deploy the SimpleStockQuoteService if not already done.
  • Start the Synapse configuration numbered 901: wso2esb-samples.sh -sn 901
 

This example invokes the one-way placeOrder operation on the SimpleStockQuoteService using the Axis2 ServiceClient.fireAndForget() API at the client. To test this, use ant -Dmode=placeorder... and you will notice the one way JMS message flowing through ESB into the sample Axis2 server instance over HTTP, and Axis2 acknowledging it with a HTTP 202 Accepted response.

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"

SimpleStockQuoteService :: Accepted order for : 7482 stocks of IBM at $ 169.27205579038733

The second example shows how ESB can be made to respond with a HTTP 202 Accepted response to a request received. The Proxy Service simply logs the message received and acknowledges it. On the ESB console you could see the logged message, and if TCPMon was used at the client, you would see the 202 Accepted response sent back to the client from ESB.

ant stockquote -Dmode=placeorder -Dtrpurl=http://localhost:8280/services/OneWayProxy
