Dear All,

Received error:

Caused by: java.lang.ClassCastException: com.webMethods.jms.impl.WmConnectionFactoryImpl incompatible with javax.jms.TopicConnectionFactory

Details:

I am using websphere 7 environemnt and trying to connect and subscribe message from web method JMS topic. We have done the following setup.

1).created one new provider in WAS-7 for webmethod broker and updated the following details in provider.

java.naming.factory.initial=com.webMethods.jms.naming.WmJmsNamingCtxFactory
java.naming.provider.url=wmjmsnaming:xxxxxxxxxxxxxxxxxxxxxxxxxxxx

2. Topic connection factory created using above provider.

3. Topic created for request(for publish) and response(subscribe).

4. Following jars are included in the provider class path

   jms.jar, wm-brokerclient.jar ,wm-g11nutils.jar,wm-jmsclient.jar ,wm-jmsnaming.jar

I got the below error during the time of web sphere listener starting and trying to listen webmethod broker from WAS7 for subscribe messaging

It seems, the error are common casting in between com.webMethods.jms.impl.WmConnectionFactoryImpl and javax.jms.TopicConnectionFactory class.

Please help me to solve this issue and provide any suggestion at websphere level (any factory type or parameter level setup need to be included in WAS-7)

I am waiting for your great reply.

Thanks and Regards

Are you trying to use JMS to access Broker?
if yes, pls read “webMethods Messaging Programmer’s Guide”

For your error, com.webMethods.jms.impl.WmConnectionFactoryImpl is not a topic factory, there is:
com.webMethods.jms.impl.WmTopicConnectionFactoryImpl
should be the one.
you are having incorrect Naming lookup somewhere.
