| <subsection name="Pre-requisites"> |
| <p> |
| <ul> |
| <li> |
| Start Synapse using the configuration numbered 702 (repository/conf/sample/synapse_sample_702.xml) |
| <div class="command"> |
| Unix/Linux: sh synapse.sh -sample 702<br/> |
| Windows: synapse.bat -sample 702 |
| </div> |
| </li> |
| </ul> |
| </p> |
| </subsection> |
| <subsection name="Executing the Client"> |
| <p> |
| Execute the sample client a few times with the following command. Note that |
| we still haven't started the sample Axis2 server. |
| </p> |
| <div class="command"> |
| ant stockquote -Daddurl=http://localhost:9000/services/SimpleStockQuoteService -Dtrpurl=http://localhost:8280/ -Dmode=placeorder |
| </div> |
| |
| <p> |
| Deploy the SimpleStockQuoteService in the sample Axis2 server and start Axis2. |
| </p> |
| <p> |
| When you start the service you will see messages getting delivered to the service, |
| even though the service was actually down when we invoked the sample client. |
| </p> |
| <p> |
| Here in the 'main' sequence store mediator will store the placeOrder request |
| message in the 'MyStore' message store. Message processor will send the message |
| to the endpoint which is configured as a message context property. Message |
| processor will remove the message from the store only if the message is delivered |
| successfully. |
