Spring JMS & Weblogic 9.2

[Java_Maniac]

I'm having some problems with Spring JMS on Weblogic 9.2. The stack trace I'm getting looks like this,

Having had a read around on the forum, it seems that the

java.lang.IllegalArgumentException: Cannot convert value of type [javax
.naming.Reference] to required type [javax.jms.ConnectionFactory] for property

Is often found if there are multiple jms.jar on the app server classpath, or if it's been included within the war/ear itself. From what I can see, the only javax.jms libraries available to the application are from within weblogic.jar, yet, I still seem to have the problem.

Wondering whether anyone has seen anything similar, and managed to overcome it - or would have a strategy on how I can overcome it!

Hate these classloader type issues!!

Thanks in advance,
Seth

Thought I'd better add this, as you can see, all pretty 'sandbox'.

    <!-- Spring JMS Queue Connection Factory -->
    <bean id="jmsQueueConnectionFactory"
        class="org.springframework.jms.connection.SingleConnectionFactory102">
        <property name="targetConnectionFactory">

        </property>
        <property name="pubSubDomain">
            <value>false</value>

Thought I'd answer this just in case someone thought or finds they're having a similar problem. My JMS queue is in fact IBM Websphere MQ JMS, and the problem was that I was missing some IBM specific jars from my classpath.

Therefore, if you're using IBM MQ and having this problem, check your dependencies - maybe!

Good luck...
