PostHeaderIcon Mule / MQJE001 / MQJMS2007

Case

In a Mule ESB workflow, the endpoint is a <jms:outbound-endpoint>, pointing to a JMS queue hosted on MQ Series and accessed through WebLogic 10.3.3.

I get the following stracktrace

Exception stack is:
1. MQJE001: Completion Code 2, Reason 2027 (com.ibm.mq.MQException)
com.ibm.mq.MQQueue:1624 (null)
2. MQJMS2007: failed to send message to MQ queue(JMS Code: MQJMS2007) (javax.jms.JMSException)
com.ibm.mq.jms.services.ConfigEnvironment:622 (http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/jms/JMSException.html)
3. Failed to create and dispatch response event over Jms destination "queue://MQSERVER/AMQ.4C8A5E112285475605?persistence=1". Failed to route event via endpoint: null. Message payload is of type: JMSObjectMessage (org.mule.api.transport.DispatchException)
org.mule.transport.jms.JmsReplyToHandler:154 (http://www.mulesource.org/docs/site/current2/apidocs/org/mule/api/transport/DispatchException.html)

Fix

On Mule config file, explicitly set the attribute disableTemporaryReplyToDestinations at true in the JMS outbound tag:

<jms:outbound-endpoint
 queue="jonathan.lalou.jms.queue"
 connector-ref="jmsConnector"
 transformer-refs="foo" disableTemporaryReplyToDestinations="true"/>

PostHeaderIcon Mule / MQJMS3000: failed to create a temporary queue from SYSTEM.DEFAULT.MODEL.QUEUE

Case

I have a Mule workflow, of which outbound is a <jms:outbound-endpoint>. The destination queue is hosted on MQ Series and accessed through WebLogic 10.3.3 bridge.

I get the following error:

MQJMS3000: failed to create a temporary queue from SYSTEM.DEFAULT.MODEL.QUEUE

Explanation

A similar issue is described here on Mule support forum. Richard Swart wrote:

This not really mule specific error but an MQ authorization error. The QueueSession.createTemporaryQueue method needs access to the model queue that is defined in the QueueConnectionFactory temporaryModel field (by default this is SYSTEM.DEFAULT.MODEL.QUEUE).

Quick Fix

To fix the issue: on MQ server side, grant visibility to client applications on the default SYSTEM.DEFAULT.MODEL.QUEUE

PostHeaderIcon Tutorial: Use WebShere MQ as JMS provider within WebLogic 10.3.3, and Mule ESB as a client

Abstract

You have an application deployed on WebLogic 10 (used version for this tutorial: 10.3.3). You have to use an external provider for JMS, in our case MQ Series / WebSphere MQ.
The client side is a Mule ESB launched in standalone.

Prerequisites

You have:

  • a running WebLogic 10 with an admin instance and an another instance, in our case: Muletier.
  • a file file.bindings, used for MQ.

JARs installation

  • Stop all your WebLogic 10 running instances.
  • Get the JARs from MQ Series folders:
    • providerutil.jar
    • fscontext.jar
    • dhbcore.jar
    • connector.jar
    • commonservices.jar
    • com.ibm.mqjms.jar
    • com.ibm.mq.jar
  • Copy them in your domain additional libraries folder (usually: user_projects/domains/jonathanApplication/lib/)
  • Start WebLogic 10 admin. A block like this should appear:
    &lt;Oct 15, 2010 12:09:21 PM CEST&gt; &lt;Notice&gt; &lt;WebLogicServer&gt; &lt;BEA-000395&gt; &lt;Following extensions directory contents added to the end of the classpath:
    C:\win32app\bea\user_projects\domains\jonathanApplication\lib\com.ibm.mq.jar;C:\win32app\bea\user_projects\domains\jonathanApplication\lib\com.ibm.mqjms.jar;C:\win32app\bea\user_projects\domains\jonathanApplication\lib\commonservices.jar;C:\win32app\bea\user_projects\domains\jonathanApplication\lib\connector.jar;C:\win32app\bea\user_projects\domains\jonathanApplication\lib\dhbcore.jar;C:\win32app\bea\user_projects\domains\jonathanApplication\lib\fscontext.jar;C:\win32app\bea\
    user_projects\domains\jonathanApplication\lib\providerutil.jar&gt;

Config

  • Get file.bindings, copy it into user_projects/domains/jonathanApplication/config/jms, rename it as .bindings (without any prefix)
  • Launch the console, login
  • JMS > JMS Modules > Create JMS System Module > Name: JmsMqModule. Leave other fields empty. > Next > target server MuleTier > Finish
  • Select JmsMqModule > New > Foreign Server > Name: MQForeignServer > keep check MuleTier > Finish
    • Select MQForeignServer >
    • Tab Connection Factories > New >
      • Name: MQForeignConnectionFactory
      • Local JNDI Name: the JNDI name on WebLogic side, eg: jonathanApplication/jms/connectionFactory/local (convention I could observe: separator on WebLogic: slash '/' ; unlike clients for which the separator in a dot '.')
      • Remote JNDI Name: the JNDI name on MQ side, eg: JONATHAN_APPLICATION.QCF
      • OK
    • Tab Destinations > New >
      • Queue of requests:
        • Name: JONATHAN.APPLICATION.REQUEST
        • Local JNDI Name: JONATHAN.APPLICATION.REQUEST
        • Remote JNDI Name: JONATHAN.APPLICATION.REQUEST
      • Queue of response:
        • Name: JONATHAN.APPLICATION.REPONSE
        • Local JNDI Name: JONATHAN.APPLICATION.REPONSE
        • Remote JNDI Name: JONATHAN.APPLICATION.REPONSE
      • NB: usually, MQ data are upper-cased and Java’s JNDI names are low-cased typed ; anyway (because of Windows not matching case?) here we use uppercase in for both names.

Mule

This part of the tutorial deals with a case of Mule ESB being your client application (sending and/or receiving JMS messages).

  • Get the archive wlfullclient.jar (56MB). Alternatively, you can generate it yourself: go to the server/lib directory of your WebLogic installation (usually: C:\win32app\bea\wlserver_10.3\server\lib, and run: java -jar wljarbuilder.jar
  • Copy the archive into $MULE_HOME/lib/user
  • Copy the seven jars above (providerutil.jar, fscontext.jar, dhbcore.jar, connector.jar, commonservices.jar, com.ibm.mqjms.jar, com.ibm.mq.jar) into the same folder: $MULE_HOME/lib/user
  • You can launch the mule. The config file is similar to any other configuration using standard JMS.
