+ <p>
+ <strong>Prerequisites:</strong><br/> Start the Synapse configuration numbered 157: i.e. wso2esb-samples -sn 157
+ <br/>Start the Axis2 server and deploy the SimpleStockQuoteService if not already done.
+ For this particular case we will be using 'curl' to send requests with custom HTTP Headers to the proxy service. You may use a similar tool with facilitate those requirements.
+ <br/><br/>The request file : stockQuoteReq.xml, should contain the following request.
