The WSO2 JMS transport can be configured with IBM® WebSphere® MQ. The following topics cover the configuration steps.

 

The configuration steps below are for a Windows environment. Similar steps apply for other environments such as OSX and Linux.

Prerequisites

Creating queue manager, queue and channel in IBM WebSphere MQ

  1. Start IBM WebSphere MQ Explorer as an administrator. If you are not running on an administrator account, right-click on the IBM WebSphere MQ icon/menu item and then click Run as Administrator.
  2. Right-click on Queue Managers, move the cursor to New and then click Queue Manager to open the Create Queue Manager wizard. Enter ESBQManager as the queue manager name. Make sure you select the make this the default queue manager check box. Leave the default values unchanged in the other fields. Click Next to move to the next page. 
  3. Click Next on the page for entering data and log values without changing any default values.
  4. On the page for entering configuration options, specify the configuration options as done in the following diagram, and click Next.
     

  5. Configure the following in the page for entering listener options.

    Field NameValue
    Create listener configured for TCP/IP check boxSelect this check box to create the listener.
    Listen on port number fieldEnter the number of the port where you want to set the listener. In this example, the port number will be 1414.
  6. Click Next and then click Finish to save the configuration. The queue manager will be created as shown below.
  7. Expand the navigation tree of the ESBQManager queue manager in the navigation tree. Right-click on Queues, move the cursor to New and then click Local Queue to open the Create a Local Queue wizard. Enter the local queue name as LocalQueue1 and complete running the wizard. Leave the default values of all other fields unchanged, and click Finish to save the local queue. 
  8. Right-click on Channels, move the cursor to  New , and then click Server-connection Channel to open the Create a Server-connection Channel wizard. Enter myChannel as the channel name and click Next. Make sure that the value for the Transmission Protocol is TCP. Leave the default values unchanged for the rest of the fields, and click Finish to save the channel.

Generating the .bindings file

  1. Create a directory in which the .bindings file can be saved in any location of your computer. In this example, a directory named jndidirectory will be created in the G folder.
  2. Go to IBM Websphere MQ, and click JMS Administered Objects, and then click Add Initial Context.
  3. Select the File system option in the Connection Details  wizard as shown below. Enter file:G/jndidirectory in the Context nickname field. Leave the default values unchanged for other fields and complete running the wizard. The new file initial context will be  displayed in the left navigator under JMS Administered Objects.
  4. Click on the file initial context (named file:G/jndidirectory in this example) in the navigator to expand it. Right-click on Connection Factories, move the cursor to New, and then click Connection Factory. Enter the name of the connection factory as MyQueueConnectionFactory. Select Queue Connection Factory as the connection factory type. Leave the default values unchanged for other fields and complete running the wizard.
  5. Right-click on the newly connected connection factory in the left navigator, and click Properties. Then click Connection and browse to select ESBQManager as the Base queue manager. You can change the host and port name for the connection factory if required. No changes will be made in this example since the default values are used. Leave the default values unchanged for other fields and click OK.
  6. Right-click Destination under JMS Administered Objects in the left navigator. Move the cursor to New and then click Destination to open the New Destination wizard. In order to map the destination to the local queue you created in step 7 of the Creating queue manager, queue and channel in IBM WebSphere MQ section, enter the same queue name (LocalQueue1 in this example) in the Name field. Select ESBQManager  as the queue manager and LocalQueue1 as the queue in the wizard. Leave the default values unchanged for other fields and complete running the wizard.

The .bindings file will be created in the location you specified (file:G/jndidirectory in this example) after you carry out the above steps.

In order to connect to the queue, you need to configure channel authentication. Run the following two commands to disable channel authentication for the ease of use. 

Note that you have to run the command prompt as a admin user and run these commands.

runmqsc ESBQManager
ALTER QMGR CHLAUTH(DISABLED)

The following will be displayed in the command prompt.


Configuring WSO2 ESB JMS transport

  • If you use the default configuration of the IBM MQ queue manager, you need to provide username and password client authentication. The username and password that you need to provide here is the username and password that you provide to log on to your operating system.
  • The vender.class.loader.enabled parameter in the above configuration should be added only when you use IBM Websphere MQ as the JMS broker.
  • WSO2 uses some external class loader mechanisms for some external products such as QPID and AMQP due to the limitation of serializing the JMSObject message. However, it is not required to use this mechanism for IBM Websphere MQ. By adding the vender.class.loader.enabled parameter, you can skip the external class loader for IBM Websphere MQ.
  • This property can also be included in a proxy service, REST API, message store, JMS receiver or the Synapse configuration depending on the use case.
  • If you are using Windows Operating Systems (e.g., Windows 10), mention the .bindings file location starting with file:/// format, in the below <transportReceiver'> and <transportSender> configurations in the <ESB_HOME>/repository/conf/axis2/axis2.xml file as follows: <parameter name="java.naming.provider.url" locked="false">file:///G:/jndidirectory</parameter> 

  1. Add the following transport receiver to the <ESB_HOME>/repository/conf/axis2/axis2.xml file. 

    <transportReceiver name="jms" class="org.apache.axis2.transport.jms.JMSListener">
  <parameter name="default" locked="false">
    <parameter name="java.naming.factory.initial" locked="false">com.sun.jndi.fscontext.RefFSContextFactory</parameter>

    <parameter name="transport.jms.Password" locked="false">password</parameter>
  </parameter>
</transportSender>

Copying IBM Websphere MQ libraries

Follow the instructions below to build and install IBM WebSphere MQ client JAR files to WSO2 ESB.

These instructions are tested on IBM WebSphere MQ version 8.0.0.4. However, you can follow them for other versions appropriately.

  1. Create a new directory named wmq-client, and then create another new directory named lib inside it.

  2. Copy the following JAR files from the <IBM_MQ_HOME>/java/lib/ directory to the wmq-client/lib/ directory.

    <IBM_MQ_HOME> refers to the IBM WebSphere MQ installation directory.

    • com.ibm.mq.allclient.jar

    • fscontext.jar

    • jms.jar

    • providerutil.jar

  3. Create a POM.xml file inside the wmq-client/ directory and add all the required dependencies as shown in the example below.

    You need to change the values of the <version> and <systemPath> properties accordingly.

    <?xml version="1.0"?>

  4. Navigate to the wmq-client directory using your Command Line Interface (CLI), and execute the following command, to build the project: mvn clean install

  5. Stop the WSO2 ESB server, if it is already running. 

  6. Remove any existing IBM MQ client JAR files from the <ESB_HOME>/repository/components/dropins/ directory and the <ESB_HOME>/repository/components/lib/ directory.

  7. Copy the <wmq-client>/target/wmq-client-8.0.0.4.jar file to the <ESB_Home>/repository/components/dropins/ directory.

  8. Copy the <wmq-client>/target/jta.jar file to the <ESB_HOME>/repository/components/lib/ directory.

  9. Remove following line from the <ESB_HOME>/repository/conf/etc/launch.ini file: javax.jms,\

  10. Regenerate .bindings file with the Provider Version : 8 property (if you already generated one before), and replace the existing .bindings file (if you have one) with the new .bindings file you generated.

  11. Start the WSO2 ESB server.

Deploying JMS listener proxy service

In this section, the following simple proxy service is deployed to listen to the LocalQueue1 queue. When a message is published in this queue, the proxy service would pull the message out of the queue and log it. See Proxy Services for detailed instructions for creating a proxy service.

<proxy xmlns="http://ws.apache.org/ns/synapse"
       name="MyJMSProxy"
       transports="jms"
       startOnLoad="true"
       trace="disable">
   <description/>
   <target>
      <inSequence>
         <log level="full"/>
         <drop/>
      </inSequence>
   </target>
   <parameter name="transport.jms.Destination">LocalQueue1</parameter>
</proxy>


Testing the proxy service

Open IBM Websphere MQ and publish a message to LocalQueue1. 

The message will be logged in the ESB Management console as well as the log file.


Sample Scenarios

This section describes how to configure the following sample scenarios using the JMS transport, WebSphere MQ, and WSO2 ESB:

In scenarios where the client places the message directly on the queue or topic, and the message is then picked up by the ESB, you configure the non-default connection factories in <ESB_HOME>\repository\conf\axis2\axis2.xml and comment them out in the <ESB_HOME>\samples\axis2Server\repository\conf\axis2.xml file. In scenarios where the client sends the message to the ESB first, and the ESB places the message on the queue or topic, you configure the non-default connection factories in <ESB_HOME>\samples\axis2Server\repository\conf\axis2.xml and comment them out in <ESB_HOME>\repository\conf\axis2\axis2.xml.

Queue Scenario 1: Client to Queue to ESB

In this scenario, the JMS client places an order on the JMS_QUEUE queue. The ESB listens on this queue, gets the message, and sends it to the back-end server to process. 

  1. In <ESB_HOME>\repository\conf\axis2\axis2.xml, comment out the myTopicConnectionFactory parameter and uncomment the SQProxyCF parameter. It should look as shown below.

    <transportReceiver name="jms" class="org.apache.axis2.transport.jms.JMSListener">
    <!--parameter name="myTopicConnectionFactory" locked="false"> 
      <parameter name="java.naming.factory.initial" 
locked="false">com.sun.jndi.fscontext.RefFSContextFactory</parameter>
      <parameter name="java.naming.provider.url" locked="false">file:/C:/JNDI-Directory</parameter>
      <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">MQ_JMS_MANAGER</parameter>
      <parameter name="transport.jms.ConnectionFactoryType" locked="false">topic</parameter>
      <parameter name="transport.jms.Destination">JMS_QUEUE</parameter>
    </parameter--> 

    <parameter name="SQProxyCF" locked="false">
      <parameter name="java.naming.factory.initial">com.sun.jndi.fscontext.RefFSContextFactory</parameter>
      <parameter name="java.naming.provider.url">file:/C:/JNDI-Directory</parameter>
      <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">MQ_JMS_MANAGER</parameter>
      <parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
      <parameter name="transport.jms.Destination">JMS_QUEUE</parameter>
    </parameter>

    <parameter name="default" locked="false">
      <parameter name="java.naming.factory.initial" 
locked="false">com.sun.jndi.fscontext.RefFSContextFactory</parameter>
      <parameter name="java.naming.provider.url" locked="false">file:/C:/JNDI-Directory</parameter>
      <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">MQ_JMS_MANAGER</parameter>
      <parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
      <parameter name="transport.jms.Destination">JMS_QUEUE</parameter>
    </parameter>
</transportReceiver>

  2. If you are using version 6.0 of IBM WebSphere MQ, add the following parameter to axis2.xml to ensure that JMS Spec version 1.1.2b is used instead of version 1.1:

    <parameter name="transport.jms.JMSSpecVersion">1.0.2b</parameter>

     

  3. Start the ESB with the Sample 250 configuration by running the following command.
    wso2esb-samples.bat -sn 250

  4. Log in to the server management console at: https://localhost:9443/carbon/.

  5. Click Services -> list -> StockQuoteProxy -> edit (Specific Configuration)

  6. Add a service parameter as follows and save it.
    name = transport.jms.ConnectionFactory value = SQProxyCF

  7. Go to the <ESB_HOME>/samples/axis2Client directory and build it using the ant command.

  8. Go to the <ESB_HOME>/samples/axis2Client/src/samples/userguide directory, open the GenericJMSClient.java source file, and make the following changes in the code:

    1. Set the jms_dest property default value to JMS_QUEUE (line 45)

    2. Set the java.naming.provider.url to file:/C:/JNDI-Directory (line 82)

    3. Set the java.naming.factory.initial to com.sun.jndi.fscontext.RefFSContextFactory (line 85)

    4. Set the lookup key to MQ_JMS_MANAGER (line 89)

  9. Configure the proxy configuration so that it appears as follows.

    <definitions xmlns="http://ws.apache.org/ns/synapse">
  <proxy name="StockQuoteProxy" transports="https http jms" startOnLoad="true" trace="disable">
    <target>
      <endpoint>
        <address uri="http://localhost:9000/services/SimpleStockQuoteService"/>
      </endpoint>
      <inSequence>
        <property name="OUT_ONLY" value="true"/>
      </inSequence>
      <outSequence>
        <send/>
      </outSequence>
    </target>
    <publishWSDL uri="file:repository/samples/resources/proxy/sample_proxy_1.wsdl"/>
    <parameter name="transport.jms.ContentType">
      <rules>
        <jmsProperty>contentType</jmsProperty>
        <default>application/xml</default>
      </rules>
    </parameter>
    <parameter name="transport.jms.ConnectionFactory">SQProxyCF</parameter>
  </proxy>
  <sequence name="fault">
    <log level="full">
      <property name="MESSAGE" value="Executing default "fault" sequence"/>
      <property name="ERROR_CODE" expression="get-property('ERROR_CODE')"/>
      <property name="ERROR_MESSAGE" expression="get-property('ERROR_MESSAGE')"/>
    </log>
    <drop/>
  </sequence>
  <sequence name="main">
    <log/>
    <drop/>
  </sequence>
</definitions>

  10. Configure <ESB_HOME>\samples\axis2Server\repository\conf\axis2.xml so that it looks as follows.

    <transportReceiver name="jms" class="org.apache.axis2.transport.jms.JMSListener">
  <!--parameter name="myTopicConnectionFactory" locked="false">
    <parameter name="java.naming.factory.initial" 
locked="false">com.sun.jndi.fscontext.RefFSContextFactory</parameter>
    <parameter name="java.naming.provider.url" locked="false">file:/C:/JNDI-Directory</parameter>
    <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">MQ_JMS_MANAGER</parameter>
    <parameter name="transport.jms.ConnectionFactoryType" locked="false">topic</parameter>
    <parameter name="transport.jms.Destination">JMS_QUEUE</parameter>
  </parameter-->

  <!--parameter name="SQProxyCF" locked="false">
    <parameter name="java.naming.factory.initial">com.sun.jndi.fscontext.RefFSContextFactory</parameter>
    <parameter name="java.naming.provider.url">file:/C:/JNDI-Directory</parameter>
    <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">MQ_JMS_MANAGER</parameter>
    <parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
    <parameter name="transport.jms.Destination">JMS_QUEUE</parameter>
  </parameter-->

  <parameter name="default" locked="false">
    <parameter name="java.naming.factory.initial" 
locked="false">com.sun.jndi.fscontext.RefFSContextFactory</parameter>
    <parameter name="java.naming.provider.url" locked="false">file:/C/JNDI-Directory</parameter>
    <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">MQ_JMS_MANAGER</parameter>
    <parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
    <parameter name="transport.jms.Destination">JMS_QUEUE</parameter>
  </parameter>
</transportReceiver>

  11. Start the axis2 Server with the following command. 
    axis2Server.bat

  12. Send the request from the JMS client, and the sample Axis2 server console will print a message.
    ant jmsclient -Djms_type=pox -Djms_dest=JMS_QUEUE -Djms_payload=MSFT

Queue Scenario 2: Client to ESB to Queue

In this scenario, the JMS client places an order to the ESB, which then places it on the queue. The back-end server listens on this queue, and then gets the message and processes the request.  

  1. In <ESB_HOME>\repository\conf\axis2\axis2.xml, comment out both the myTopicConnectionFactory parameter and the SQProxyCF parameter. It should look as shown below.

    <transportReceiver name="jms" class="org.apache.axis2.transport.jms.JMSListener">
    <!--parameter name="myTopicConnectionFactory" locked="false"> 
      <parameter name="java.naming.factory.initial" 
locked="false">com.sun.jndi.fscontext.RefFSContextFactory</parameter>
      <parameter name="java.naming.provider.url" locked="false">file:/C:/JNDI-Directory</parameter>
      <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">MQ_JMS_MANAGER</parameter>
      <parameter name="transport.jms.ConnectionFactoryType" locked="false">topic</parameter>
      <parameter name="transport.jms.Destination">JMS_QUEUE</parameter>
    </parameter--> 

    <!--parameter name="SQProxyCF" locked="false">
      <parameter name="java.naming.factory.initial">com.sun.jndi.fscontext.RefFSContextFactory</parameter>
      <parameter name="java.naming.provider.url">file:/C:/JNDI-Directory</parameter>
      <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">MQ_JMS_MANAGER</parameter>
      <parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
      <parameter name="transport.jms.Destination">JMS_QUEUE</parameter>
    </parameter-->

    <parameter name="default" locked="false">
      <parameter name="java.naming.factory.initial" 
locked="false">com.sun.jndi.fscontext.RefFSContextFactory</parameter>
      <parameter name="java.naming.provider.url" locked="false">file:/C:/JNDI-Directory</parameter>
      <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">MQ_JMS_MANAGER</parameter>
      <parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
      <parameter name="transport.jms.Destination">JMS_QUEUE</parameter>
    </parameter>
</transportReceiver>

  2. Start the ESB with the Sample 251 configuration using the following command. 
    wso2esb-samples.bat -sn 251

  3. Log into the ESB server management console at: https://localhost:9443/carbon/.
  4. Select Service Bus -> Source view and update the JMS URL as follows.
    jms:/JMS_QUEUE?transport.jms.ConnectionFactoryJNDIName=MQ_JMS_MANAGER&java.naming.factory.initial=com.sun.jndi.fscontext.RefFSContextFactory&java.naming.provider.url=file:/C:/JNDI-Directory&transport.jms.DestinationType=queue&transport.jms.ConnectionFactoryType=queue &transport.jms.Destination=JMS_QUEUE

  5. Configure the proxy service as follows.

    <definitions xmlns="http://ws.apache.org/ns/synapse">
  <proxy name="StockQuoteProxy" transports="https http jms" startOnLoad="true" trace="disable">
    <target>
      <endpoint>
        <address uri="jms:/JMS_QUEUE?transport.jms.ConnectionFactoryJNDIName=MQ_JMS_MANAGER&java.naming.factory.initial=com.sun.jndi.fscontext.RefFSContextFactory&java.naming.provider.url=file:/C:/JNDI-Directory&transport.jms.DestinationType=queue&transport.jms.ConnectionFactoryType=queue&transport.jms.Destination=JMS_QUEUE"/>
      </endpoint>
      <inSequence>
        <property name="TRANSPORT_HEADERS" scope="axis2" action="remove"/>
        <property name="OUT_ONLY" value="true"/>

  6. Go to the <ESB_HOME>/samples/axis2Client directory and build it using the ant command.  

  7. Go to the <ESB_HOME>/samples/axis2Client /src/samples/userguide directory, open the GenericJMSClient.java source file, and make the following changes in the code.

    1. Set the jms_dest property default value to ivtT (line 45)

    2. Set the java.naming.provider.url to file:/C:/JNDI-Directory" (line 82)

    3. Set the java.naming.factory.initial to com.sun.jndi.fscontext.RefFSContextFactory (line 85)

    4. Set the lookup key to MQ_JMS_MANAGER (line 89)
