Using the JMS Inbound Endpoint

This sample demonstrates how one way message bridging from JMS to HTTP can be done using the inbound JMS endpoint.

Synapse configuration

Following are the integration artifacts that we can used to implement this scenario. See the instructions on how to build and run this example.

 <?xml version="1.0" encoding="UTF-8"?>
 <inboundEndpoint xmlns="http://ws.apache.org/ns/synapse" name="jms_inbound" sequence="request" onError="fault" protocol="jms" suspend="false">
    <parameters>
       <parameter name="interval">1000</parameter>
       <parameter name="transport.jms.Destination">ordersQueue</parameter>
       <parameter name="transport.jms.CacheLevel">1</parameter>
       <parameter name="transport.jms.ConnectionFactoryJNDIName">QueueConnectionFactory</parameter>
       <parameter name="sequential">true</parameter>
       <parameter name="java.naming.factory.initial">org.apache.activemq.jndi.ActiveMQInitialContextFactory</parameter>
       <parameter name="java.naming.provider.url">tcp://localhost:61616</parameter>
       <parameter name="transport.jms.SessionAcknowledgement">AUTO_ACKNOWLEDGE</parameter>
       <parameter name="transport.jms.SessionTransacted">false</parameter>
       <parameter name="transport.jms.ConnectionFactoryType">queue</parameter>
    </parameters>
 </inboundEndpoint>
<?xml version="1.0" encoding="UTF-8"?>
<sequence name="request" trace="disable" xmlns="http://ws.apache.org/ns/synapse"/>
  <call>
     <endpoint>
        <address format="soap12" uri="http://localhost:9000/services/SimpleStockQuoteService"/>
     </endpoint>
  </call>
  <drop/>
</sequence>

Build and run

Create the artifacts:

  1. Set up ESB Integration Studio.
  2. Create an integration project with an ESB Configs module and an Composite Exporter.
  3. Create a mediation sequence and inbound endpoint with configurations given in the above example.
  4. Deploy the artifacts in your Micro Integrator.

Configure the ActiveMQ broker.

Invoke the inbound endpoint:

  1. Log on to the ActiveMQ console using the http://localhost:8161/admin URL.
  2. Browse the queue ordersQueue listening via the above endpoint.

  3. Add a new message with the following content to the queue:

    <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsa="http://www.w3.org/2005/08/addressing">
    <soapenv:Body>
        <m0:getQuote xmlns:m0="http://services.samples"> 
            <m0:request>
                <m0:symbol>IBM</m0:symbol>
            </m0:request>
        </m0:getQuote>
    </soapenv:Body>
</soapenv:Envelope>

You will see that the JMS endpoint gets the message from the queue and sends it to the stock quote service.
