| <subsection name="Objective"> |
| <p> |
| Demonstrate how to use predefined endpoints and sequences in a proxy service |
| </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 151 (repository/conf/sample/synapse_sample_151.xml) |
| <div class="command"> |
| Unix/Linux: sh synapse.sh -sample 151<br/> |
| Windows: synapse.bat -sample 151 |
| </div> |
| </li> |
| </ul> |
| </p> |
| </subsection> |
| <subsection name="Executing the Client"> |
| <p> |
| This configuration creates two proxy services. The first proxy service |
| 'StockQuoteProxy1' uses the sequence named 'proxy_1' to process incoming |
| messages and the sequence named 'out' to process outgoing responses. The second |
| proxy service, 'StockQuoteProxy2' is set to directly forward messages to the |
| endpoint named 'proxy_2_endpoint' without any mediation. |
| </p> |
| <p> |
| You can send a stock quote request to each of these proxy services and receive |
| the reply generated by the actual service hosted on the Axis2 server instance. |
| </p> |
| <div class="command">ant stockquote -Daddurl=http://localhost:8280/services/StockQuoteProxy1 |
| <br/>ant stockquote -Daddurl=http://localhost:8280/services/StockQuoteProxy2</div> |
