Executing the Client
In this sample, the Callout mediator does the direct service invocation to the StockQuoteService using the client request, gets the response, and sets it as the first child of the SOAP message body. Callout Mediator uses the inline endpoint to send the message to the StockQuoteService.
Invoke the client as follows.
ant stockquote -Daddurl=http://localhost:8280/
