                <p>
                    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 defined endpoint
                    named 'StockQuoteServiceEndpoint' to send the message to the StockQuoteService.
                </p>
                <p>
                    Invoke the client as follows.
