| <subsection name="Objective"> |
| <p> |
| Demonstrate the ability to perform one-way invocations (out-only) through |
| Synapse. |
| </p> |
| </subsection> |
| <subsection name="Pre-requisites"> |
| <p> |
| <ul> |
| <li> |
| Deploy the SimpleStockQuoteService in the sample Axis2 server and start Axis2 |
| </li> |
| <li> |
| This sample makes use of the configuration used in <a href="sample1.html">sample 1</a>. |
| So start Synapse using the configuration numbered 1 (repository/conf/sample/synapse_sample_1.xml) |
| <div class="command"> |
| Unix/Linux: sh synapse.sh -sample 1<br/> |
| Windows: synapse.bat -sample 1 |
| </div> |
| </li> |
| </ul> |
| </p> |
| </subsection> |
| <subsection name="Executing the Client"> |
| <p> |
| In this example we will invoke the one-way 'placeOrder' operation on the |
| SimpleStockQuoteService using the sample client which uses the Axis2 |
| ServiceClient.fireAndForget() API. To send a placeOrder request from the sample |
| client, execute the following command. |
| </p> |
| <div class="command">ant stockquote -Daddurl=http://localhost:9000/services/SimpleStockQuoteService -Dtrpurl=http://localhost:8280/ -Dmode=placeorder</div> |
| |
| <p> |
| Going through the Axis2 server logs, you will notice the following entry, which |
| confirms that Axis2 accepted the in-only request. |
| </p> |
| <div class="consoleOutput">SimpleStockQuoteService :: Accepted order for : 7482 stocks of IBM at $ 169.27205579038733</div> |
| |
| <p> |
| If you send your client request through TCPmon, you will notice that the |
| SimpleStockQuoteService replies to Synapse with a HTTP 202 reply, and that Synapse |
| in turns replies to the client with a HTTP 202 acknowledgment. |
