Sample 656: Message Relay - Builder Mediator

Objective:Demonstrate the Message Relay with Builder mediator.

This sample is similar to sample 655. We have added the builder mediator to build the actual message before logging it.

  <sequence name="main">

    <drop/>
  </sequence>
</definitions>

Prerequisites:Set up is same as sample 655.

ant stockquote -Daddurl=http://localhost:8280/services/StockQuoteProxy

You can see the actual messages going through the proxy by looking at the console because we have two log mediators in this sample. Becuase we have the builder mediator in place, unlike in sample 655 we have the actual message printed.
