| <subsection name="Objective"> |
| <p> |
| This sample demonstrates the ability of Synapse to perform transport switching |
| between JMS and HTTP. It also shows how to configure a one-way HTTP proxy in |
| Synapse. |
| </p> |
| </subsection> |
| <subsection name="Pre-requisites"> |
| <p> |
| <ul> |
| <li> |
| Deploy the SimpleStockQuoteService in the sample Axis2 server and start Axis2 |
| </li> |
| <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 Synapse (Refer |
| <a href="setup/jms.html#listener">JMS setup guide</a> for more details) |
| </li> |
| <li> |
| Start Synapse using the configuration numbered 253 (repository/conf/sample/synapse_sample_253.xml) |
| <div class="command"> |
| Unix/Linux: sh synapse.sh -sample 253<br/> |
| Windows: synapse.bat -sample 253 |
| </div> |
| </li> |
| </ul> |
| </p> |
| </subsection> |
| <subsection name="Executing the Client"> |
| <p> |
| This example invokes the one-way 'placeOrder' operation on the SimpleStockQuoteService |
| using the Axis2 ServiceClient.fireAndForget() API at the client. To test this, |
| run the sample client as follows and you will notice the one-way JMS message |
| flowing through Synapse into the sample Axis2 server instance over HTTP, and Axis2 |
| acknowledging it with a HTTP 202 Accepted response. |
| </p> |
| <div class="command">ant stockquote -Dmode=placeorder -Dtrpurl="jms:/JMStoHTTPStockQuoteProxy?\ |
| transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory\ |
| &java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory\ |
| &java.naming.provider.url=tcp://localhost:61616\ |
| &transport.jms.ContentTypeProperty=Content-Type&transport.jms.DestinationType=queue"</div> |
| <p> |
| The second example shows how Synapse could be made to respond with a HTTP 202 |
| Accepted response to a request received. The proxy service simply logs the message |
| received and acknowledges it. To try this out, run the sample client as follows. |
| </p> |
| <div class="command">ant stockquote -Dmode=placeorder -Dtrpurl=http://localhost:8280/services/OneWayProxy</div> |
| <p> |
| On the Synapse console you could see the logged message, and if TCPMon was used |
| at the client, you would see the 202 Accepted response sent back to the client |
| from Synapse. |
| </p> |
