| <subsection name="Objective"> |
| <p> |
| This sample demonstrates receiving messages over HTTP/S and forwarding them to |
| a JMS queue |
| </p> |
| </subsection> |
| <subsection name="Pre-requisites"> |
| <p> |
| <ul> |
| <li> |
| Setup and start a JMS broker (Apache ActiveMQ can be used as the |
| JMS broker for this scenario. Refer <a href="setup/jms.html#pre">JMS setup guide</a> |
| for information on how to run ActiveMQ.) |
| </li> |
| <li> |
| Enable the JMS transport receiver of the sample Axis2 server (Refer |
| <a href="setup/jms.html#server">JMS setup guide</a> for details) |
| </li> |
| <li> |
| Deploy the SimpleStockQuoteService in the sample Axis2 server and start Axis2 (Since |
| the JMS receiver is enabled, Axis2 will start polling on a JMS queue) |
| </li> |
| <li> |
| Start Synapse using the configuration numbered 251 (repository/conf/sample/synapse_sample_251.xml) |
| <div class="command"> |
| Unix/Linux: sh synapse.sh -sample 251<br/> |
| Windows: synapse.bat -sample 251 |
| </div> |
| </li> |
| </ul> |
| </p> |
| </subsection> |
| <subsection name="Executing the Client"> |
| <p> |
| This Synapse configuration creates a proxy service over HTTP and forwards |
| received messages to a JMS queue. To test this functionality, send a place order |
| request to Synapse over HTTP as follows. |
| </p> |
| <div class="command">ant stockquote -Daddurl=http://localhost:8280/services/StockQuoteProxy -Dmode=placeorder -Dsymbol=MSFT</div> |
| <p> |
| Note that the target endpoint of the proxy service points to a JMS queue in the |
| ActiveMQ broker. |
| </p> |
| <div class="consoleOutput">jms:/SimpleStockQuoteService?transport.jms.ConnectionFactoryJNDIName= |
| QueueConnectionFactory&java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory& |
| java.naming.provider.url=tcp://localhost:61616</div> |
| <p> |
| The sample Axis2 server will pick up the message from the JMS queue and print the |
| following log entry. |
| </p> |
| <div class="consoleOutput">Accepted order for : 18406 stocks of MSFT at $ 83.58806051152119</div> |
