| |
| <proxy name="StockQuoteProxy"> |
| <target> |

| <subsection name="Objective"> |
| <p> |
| Show case how to engage WS-ReliableMessaging on proxy services so that the |
| communication between client and the proxy service is reliable |
| </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 201 (repository/conf/sample/synapse_sample_201.xml) |
| <div class="command"> |
| Unix/Linux: sh synapse.sh -sample 201<br/> |
| Windows: synapse.bat -sample 201 |
| </div> |
| </li> |
| </ul> |
| </p> |
| </subsection> |
| <subsection name="Executing the Client"> |
| <p> |
| In the above configuration, a proxy service is created with WS-RM enabled using |
| the <enableRM/> tag. Therefore, this proxy service is capable of |
| communicating with a WS-RM client. It also removes the WS-RM headers in the |
| inSequence before the message is sent to the backend server. This is required as |
| the reliable messaging is applicable only between the client and Synapse. Now |
| start the client with WS-RM as follows: |
| </p> |
| <div class="command">ant stockquote -Dsymbol=IBM -Dmode=quote -Daddurl=http://localhost:8280/services/StockQuoteProxy -Dwsrm=true</div> |
| <p> |
| In this case, client sends a WS-RM enabled request to Synapse where Synapse sends |
| normal requests to the server. This can be observed by examining the wire level |
| messages between the client and Synapse. These messages would be similar to the |
| wire level messages shown in <a href="sample101.html">sample 101</a>. |
