| <subsection name="Objective"> |
| <p> |
| Demonstrate how to invoke a service from Callout mediator using an inline endpoint. |
| </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 434 (repository/conf/sample/synapse_sample_434.xml) |
| <div class="command"> |
| Unix/Linux: sh synapse.sh -sample 434<br/> |
| Windows: synapse.bat -sample 434 |
| </div> |
| </li> |
| </ul> |
| </p> |
| </subsection> |
| <subsection name="Executing the Client"> |
| <p> |
| In this sample, the Callout mediator does the direct service invocation to the |
| StockQuoteService using the client request, gets the response, and sets it as the |
| first child of the SOAP message body. Callout Mediator uses the inline endpoint |
| to send the message to the StockQuoteService. |
| </p> |
| <p> |
| Invoke the client as follows. |
| </p> |
| <div class="command">ant stockquote -Daddurl=http://localhost:8280/</div> |
