| <subsection name="Objective"> |
| <p> |
| Demonstrate implementing simple transport switching and message format switching |
| scenarios using proxy services |
| </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 152 (repository/conf/sample/synapse_sample_152.xml) |
| <div class="command"> |
| Unix/Linux: sh synapse.sh -sample 152<br/> |
| Windows: synapse.bat -sample 152 |
| </div> |
| </li> |
| </ul> |
| </p> |
| </subsection> |
| <subsection name="Executing the Client"> |
| <p> |
| This configuration demonstrates how a proxy service can be exposed on a subset |
| of available transports, and how it could switch from one transport to another. |
| This example exposes the created proxy service only on HTTPS, and thus if the |
| user tries to access it over HTTP, it would result in a fault. |
| </p> |
| <div class="consoleOutput">ant stockquote -Dtrpurl=http://localhost:8280/services/StockQuoteProxy |
| ... |
| [java] org.apache.axis2.AxisFault: The service cannot be found for the endpoint reference (EPR) /soap/StockQuoteProxy</div> |
| |
| <p> |
| Accessing this over HTTPS causes the proxy service to access the SimpleStockQuoteService |
| on the sample Axis2 server using REST/POX. |
| </p> |
| <div class="command">ant stockquote -Dtrpurl=https://localhost:8243/services/StockQuoteProxy</div> |
| |
| <p> |
| TCPMon can be used to trace the actual REST/POX messages exchanged between Synapse |
| and the sample Axis2 server. Synapse converts the POX response back to SOAP before |
| sending it back to the client. |
