 				<p>JSON client will send a stockquote request to Synapse using the
					JSON content interchange format. Synapse will transform it into a SOAP
					request and forward to the Axis2 server. The SOAP response from the
					Axis2 server will be converted into a JSON message and sent back to the
					JSON client.</p>
				<p>You may use a tool like TCPMon to monitor the JSON requests sent
						over the wire. A sample JSON request and response is shown below:</p>
