| <subsection name="Objective"> |
| <p> |
| Demonstrate how to mediate and transform events before they are sent to the |
| target event sinks |
| </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 502 (repository/conf/sample/synapse_sample_502.xml) |
| <div class="command"> |
| Unix/Linux: sh synapse.sh -sample 502<br/> |
| Windows: synapse.bat -sample 502 |
| </div> |
| </li> |
| </ul> |
| </p> |
| </subsection> |
| <subsection name="Executing the Client"> |
| <p> |
| In this sample, the event (order request) is transformed into a new order with |
| a different namesapce using the XSLT mediator. Invoke the client as follows. |
| </p> |
| <div class="command">ant eventsender</div> |
| <p> |
| Event will be mediated through the 'PublicEventSource' sequence and get transformed |
| before it gets published to the event sink (Axis2 server). |
