| <subsection name="Objective"> |
| <p> |
| Showcase the ability of Synapse to receive and process raw UDP messages |
| </p> |
| </subsection> |
| <subsection name="Pre-requisites"> |
| <p> |
| <ul> |
| <li> |
| Deploy the SimpleStockQuoteService in the sample Axis2 server and start Axis2 |
| </li> |
| <li> |
| Enable the UDP transport receiver for Synapse (refer |
| <a href="setup/tcp_udp.html#udp">UDP transport setup guide</a>). |
| </li> |
| <li> |
| Start Synapse using the configuration numbered 266 (repository/conf/sample/synapse_sample_266.xml) |
| <div class="command"> |
| Unix/Linux: sh synapse.sh -sample 266<br/> |
| Windows: synapse.bat -sample 266 |
| </div> |
| </li> |
| <li> |
| Enable the UDP transport sender for the sample Axis2 client (refer |
| <a href="setup/tcp_udp.html#udp">UDP transport setup guide</a> for |
| details). |
| </li> |
| </ul> |
| </p> |
| </subsection> |
| <subsection name="Executing the Client"> |
| <p> |
| This sample is similar to <a href="sample265.html">Sample 265</a>. Only difference |
| is instead of the TCP transport we will be using the UDP transport to receive |
| messages. |
| </p> |
| <p> |
| Invoke the stockquote client using the following command. Note the UDP URL in the |
| command. |
| </p> |
| <div class="command">ant stockquote -Daddurl=udp://localhost:9999?contentType=text/xml -Dmode=placeorder</div> |
| <p> |
| Since we have configured the content type as text/xml for the proxy service, |
| incoming messages will be processed as SOAP 1.1 messages. |
| </p> |
| <p> |
| When the proxy service forwards the message to the sample Axis2 server over HTTP, |
| sample server will print the following entry to confirm that the request has |
| been received. |
