The Stock quote client can operate in the following modes for this example:

...

Refer to Sample 1 Simple Content-Based Routing (CBR) of Messages.

Prerequisites
  • Start the Synapse configuration numbered 0: for example, wso2esb-samples.sh -sn 0
  • Start the Axis2 server and deploy the SimpleStockQuoteService if not already deployed.

...

You will see exactly the same behavior as per the previous example when you run this scenario. However, this time the difference is at the client, as it sends the message to the WS-Addressing To address http://localhost:9000/services/SimpleStockQuoteService, but the transport specifies ESB as the HTTP Proxy.
