| </subsection> |
| <subsection name="Pre-requisites"> |
| <p> |
| <ul> |
| <li> |
| Deploy the SimpleStockQuoteService in the sample Axis2 server and start Axis2 Server |
| </li> |
| <li> |
| Start Synapse using the configuration numbered 800 (repository/conf/sample/synapse_sample_800.xml) |
| <div class="command"> |
| Unix/Linux: sh synapse.sh -sample 800<br/> |
| Windows: synapse.bat -sample 800 |
| </div> |
| </li> |
| </ul> |
| </p> |
| </subsection> |
| <subsection name="Executing the REST Client"> |
| <p> |
| You might need a REST client like curl to test this |
| </p> |
| <div class="command">curl -v http://127.0.0.1:8280/stockquote/view/IBM</div> |
| <div class="command">curl -v http://127.0.0.1:8280/stockquote/view/MSFT</div> |
| |
| <p> |
| The above GET calls will be handled by the first resource in the StockQuoteAPI. |
| These REST calls will get converted into SOAP calls and will be sent to the Axis2 |
| server. Response will be sent to the client in POX format. |
| </p> |
| <p> |
| The following command POSTs a simple XML to the ESB. Save following sample place |
| order request as "placeorder.xml" file in your local file system and execute the |
| command. That is used to invoke a SOAP service. ESB returns the 202 response back to the client. |
| </p> |
| <div class="command">curl -v -d @placeorder.xml -H "Content-type: application/xml" http://127.0.0.1:8280/stockquote/order/</div> |
| |
| <div class="xmlConf"><placeOrder xmlns="http://services.samples"> |
| <order> |
| <price>50</price> |
| <quantity>10</quantity> |
| <symbol>IBM</symbol> |
| </order> |
| </placeOrder></div> |
