ClassCastException: MQSession to TopicSession

[stash1071]

Hi, I recently followed the tutorial for setting up a Websphere MQ provider. I can discover the queues just fine, but am running into the following exception when trying to send a file as a text message:

Code: Select all

java.lang.ClassCastException: com.ibm.mq.jms.MQSession cannot be cast to javax.jms.TopicSession
   at hermes.impl.jms.AbstractSessionManager.createTopicProducer(AbstractSessionManager.java:518)
   at hermes.impl.jms.ThreadLocalSessionManager.getProducer(ThreadLocalSessionManager.java:550)
   at hermes.impl.DefaultHermesImpl.send(DefaultHermesImpl.java:607)

   at hermes.browser.tasks.ThreadPool.run(ThreadPool.java:170)
   at java.lang.Thread.run(Thread.java:619)

Here's my classpath group for my WMQ provider:

Code: Select all

    <classpathGroup id="WMQ">
            <library jar="/home/prystasj/HermesJMS/lib/com.ibm.mq.pcf-6.0.2.1.jar" noFactories="true"/>

            <library factories="com.ibm.mq.jms.Cleanup,com.ibm.mq.jms.MQConnectionFactory,com.ibm.mq.jms.MQQueueConnectionFactory,com.ibm.mq.jms.MQRRSConnectionFactory,com.ibm.mq.jms.MQRRSQueueConnectionFactory,com.ibm.mq.jms.MQRRSTopicConnectionFactory,com.ibm.mq.jms.MQTopicConnectionFactory,com.ibm.mq.jms.MQXAConnectionFactory,com.ibm.mq.jms.MQXAQueueConnectionFactory,com.ibm.mq.jms.MQXATopicConnectionFactory" jar="/home/prystasj/HermesJMS/lib/com.ibm.mqjms-6.0.2.1.jar" noFactories="false"/>
            <library jar="/home/prystasj/HermesJMS/lib/com.ibm.mq-6.0.2.1.jar" noFactories="true"/>
            <library jar="/home/prystasj/HermesJMS/lib/connector-1.3.0.jar" noFactories="true"/>
            <library factories="com.ibm.mq.connector.outbound.ConnectionFactoryImpl,com.ibm.mq.connector.outbound.QueueConnectionFactoryImpl,com.ibm.mq.connector.outbound.TopicConnectionFactoryImpl" jar="/home/prystasj/HermesJMS/lib/mqconnector-6.0.2.1.jar" noFactories="false"/>
    </classpathGroup>

Any thoughts to what I could be missing? Thanks in advance.

I noticed I was missing commonservices.jar, and edited the JAR list to include only:

com.ibm.mq
com.ibm.mqjms
com.ibm.mq.pcf
commonservices

Same result, hopefully I can find something else out.

Hi,

You are trying to send a file to a JMS topic and the version of MQ you have does not support it.

Can you share your hermes-config.xml?

Regards,

Colin.

I don't have access to my hermes config at the moment. But I reinstalled and started over and things seem to be working. I'll try and reverify things when I can.
Thanks
