| <subsection name="Objective"> |
| <p> |
| Introduction to Synapse - Shows how Synape can be configured to log and pass |
| messages through. |
| </p> |
| </subsection> |
| <subsection name="Pre-requisites"> |
| <p> |
| <ul> |
| <li>Deploy the SimpleStockQuoteService in the sample Axis2 server and start Axis2</li> |
| <li> |
| Start Synapse using the configuration numbered 0 (repository/conf/sample/synapse_sample_0.xml) |
| <div class="command"> |
| Unix/Linux: sh synapse.sh -sample 0<br/> |
| Windows: synapse.bat -sample 0 |
| </div> |
| </li> |
| </ul> |
| </p> |
| </subsection> |
| <subsection name="Executing the Client"> |
| <h4>Smart Client Mode</h4> |
| <p> |
| Execute the client in the smart client mode using the following command. |
| </p> |
| <div class="command">ant stockquote -Daddurl=http://localhost:9000/services/SimpleStockQuoteService -Dtrpurl=http://localhost:8280/</div> |
| <p> |
| By tracing the execution of Synapse with the log output level set to DEBUG, |
| you will see that the client request is arriving at Synapse with a WS-Addressing 'To' |
| header set to EPR http://localhost:9000/services/SimpleStockQuoteService. The |
| Synapse engine logs the message at the 'full' log level (i.e. all the |
| message headers and the body) and then sends it to its explicit 'To' |
| address which is http://localhost:9000/services/SimpleStockQuoteService. |
| You will see a log entry in the Axis2 server console confirming that the message |
| got routed to the sample server and the service hosted at the server generated |
| a stock quote for the requested symbol. |
| </p> |
| <div class="consoleOutput">Sat Nov 18 21:01:23 IST 2006 SimpleStockQuoteService :: Generating quote for : IBM</div> |
| <p> |
| The response message generated by the service is received by Synapse, |
| and flows through the same mediation rules, which log the response and |
| send back to the client. On the client console you should see an output |
| similar to the following based on the message received by the client. |
| </p> |
| <div class="consoleOutput">Standard :: Stock price = $95.26454380258552</div> |
| |
| <h4>Proxy Client Mode</h4> |
| <p> |
| Execute the sample Axis2 client as follows to run it in the proxy mode. |
| </p> |
| <div class="command">ant stockquote -Daddurl=http://localhost:9000/services/SimpleStockQuoteService -Dprxurl=http://localhost:8280/</div> |
| <p> |
| You will see the exact same behaviour as per the previous example when you run |
| this scenario. However this time the client sends the message to the Axis2 server |
| using Synapse as a HTTP proxy. |
| </p> |
| <p> |
| The Axis2 client supports another mode of operation known as the 'dumb client |
| mode'. This will be addressed in <a href="sample1.html">sample 1</a>. |
