  • Start the Synapse configuration numbered 704, e.g., -sn 704
  • Start the Axis2 server and deploy the SecureStockQuoteService if you have not done so already.

This sample demonstrate how to do RESTful invocations with the message store and message forwarding processor. Though in this sample we have used an In memory message store, these instructions are valid for any available message store implementations. Use the stockqoute client to send the following placeorder request:

ant stockquote -Daddurl=http://localhost:8280/services/StockQuoteProxy -Dmode=placeorder -Dsymbol=WSO2

You can see the message sent by the ESB to the secure service using a TCPMon. Upon successful execution, there should be a message on the back end as follows:
