| <subsection name="Objective"> |
| <p> |
| Demonstrating the ability to load endpoint definitions dynamically from the |
| remote registry. |
| </p> |
| </subsection> |
| <subsection name="Pre-requisites"> |
| <p> |
| <ul> |
| <li> |
| Deploy the SimpleStockQuoteService in the sample Axis2 server and start Axis2 |
| </li> |
| <li> |
| Start another Axis2 server instance on different ports (use the following command) |
| <div class="command" > |
| Unix/Linux: sh axis2server.sh -http 9001 -https 9003<br/> |
| Windows: axis2server.bat -http 9001 -https 9003 |
| </div> |
| </li> |
| <li> |
| Start Synapse using the configuration numbered 10 (repository/conf/sample/synapse_sample_10.xml) |
| <div class="command"> |
| Unix/Linux: sh synapse.sh -sample 10<br/> |
| Windows: synapse.bat -sample 10 |
| </div> |
| </li> |
| </ul> |
| </p> |
| </subsection> |
| <subsection name="Executing the Client"> |
| <p> |
| This example introduces dynamic endpoints, where the definition of the endpoint |
| is stored in the registry. To follow this example execute the stock quote client |
| as 'ant stockquote..' and see that the message is routed to the SimpleStockQuoteService |
| on the default Axis2 instance on HTTP port 9000. |
| </p> |
| <div class="command">ant stockquote -Dtrpurl=http://localhost:8280/</div> |
| <p> |
| Repeat the above command immediately again, and notice that the endpoint is |
| cached and reused by Synapse - similarly to <a href="sample8.html">sample 8</a>. |
| </p> |
| <p> |
| Now edit the repository/conf/sample/resources/endpoint/dynamic_endpt_1.xml file |
| and update the address to 'http://localhost:9001/services/SimpleStockQuoteService'. |
| After the cached value expires, the Registry loads the new definition of the |
| endpoint, and then the messages are routed to the second sample Axis2 server on |
| HTTP port 9001. |
