  • <PRODUCT_HOME>/repository/samples/resources/ directory that includes all artifacts related to the Integration profile samples is changed to <EI_HOME>/samples/service-bus/resources/.

Objective 1: Demonstrate the capability of working MSMQ transport messages.

Objective 2: Introduction to switching transports with proxy services


Make sure that the given MSMQ sample is ONLY working on windows environment, since it invokes Microsoft C++ API for MSMQ via JNI invocation.

  • Start the Axis2 server and deploy the SimpleStockQuoteService (Refer steps above).

  • Download the axis2-transport-msmq-2.0.0-wso2v2.jar file and add it to the <EI_HOME>/dropins directory. This file provides the JNI invocation required by MSMQ bridging. 

  • Please make sure MQ is installed and running. For more information please refer

  • Make sure that you have installed Visual C++ 2008 (VC9), it works with Microsoft Visual Studio 2008 Express.

For a default MSMQ v4.0 installation, you may place following in the Axis2 transport sender/ listener configuration at repository/conf/axis2/axis2.xml as,

<transportSender name="msmq"class="org.apache.axis2.transport.msmq.MSMQSender"/>
<transportReceiver name="msmq" class="org.apache.axis2.transport.msmq.MSMQListener">    
	<parameter name="" locked="false">localhost</parameter>

Synapse Configuration for MSMQ,

<proxy xmlns="" name="msmqTest" transports="msmq" startOnLoad="true">
            <property name="OUT_ONLY" value="true"/>
                	<address uri="http://localhost:9000/services/SimpleStockQuoteService"/>
        <parameter name="transport.msmq.ContentType">application/xml</parameter>
<proxy xmlns="" name="StockQuoteProxy" transports="http" startOnLoad="true" trace="disable">
          <address uri="msmq:DIRECT=OS:localhost\private$\msmqTest"/>
           <property name="FORCE_SC_ACCEPTED"  value="true"  scope="axis2"  type="STRING"/>
           <property name="OUT_ONLY" value="true" scope="default" type="STRING"/>
          <log level="custom">
              <property name="MESSAGE" value="OUT SEQENCE CALLED"/>
      <publishWSDL uri="http://localhost:9000/services/SimpleStockQuoteService?wsdl"/>

Invoke the sample as follows,

ant stockquote -Daddurl=http://localhost:8280/services/StockQuoteProxy -Dmode=placeorder -Dsymbol=MSFT

The sample Axis2 server console will print a message indicating that it has accepted the order as follows,

Accepted order for : 18406 stocks of MSFT at $ 83.58806051152119

Above samples works as follows,

  • Sending Place stockquote request to the ESB proxy.
  • Proxy sends the incoming message to the MSMQ server.


  • Another proxy known as ' msmqTest' listening to the MSMQ queue, invoke the message from MSMQ and send to the Aix2 back-end server.
