| <section name="Sample 150: Introduction to Proxy Services"> |
| <div class="xmlConf"><definitions xmlns="http://ws.apache.org/ns/synapse"> |
| |
| <proxy name="StockQuoteProxy"> |
| <target> |
| <endpoint> |
| <address uri="http://localhost:9000/services/SimpleStockQuoteService"/> |
| </endpoint> |
| <outSequence> |

| <subsection name="Objective"> |
| <p> |
| Introduce the concept of proxy services in Synapse |
| </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 150 (repository/conf/sample/synapse_sample_150.xml) |
| <div class="command"> |
| Unix/Linux: sh synapse.sh -sample 150<br/> |
| Windows: synapse.bat -sample 150 |
| </div> |
| </li> |
| </ul> |
| </p> |
| </subsection> |
| <subsection name="Executing the Client"> |
| <p> |
| Execute the stock quote client as follows and invoke the proxy service: |
| </p> |
| <div class="command">ant stockquote -Daddurl=http://localhost:8280/services/StockQuoteProxy</div> |
| |
| <p> |
| The 'inSequence' or 'endpoint' or both of these would decide how the message |
| would be handled after the proxy service receives the message. In the above |
| example, the request received is forwarded to the sample service hosted on Axis2. |
| The 'outSequence' defines how the response is handled before it is sent back to |
| the client. By default, a proxy service is exposed over all transportss |
| configured for Synapse, unless these are specifically mentioned through the |
| 'transports' attribute. |
| </p> |
| <p> |
| You can also view the WSDL of the proxy service by launching a web browser and |
| navigating to the following URL: |
| </p> |
| <div class="command">http://localhost:8280/services/StockQuoteProxy?wsdl</div> |
