error when connecting to websphere MQ from PI 7.3 using jms

[Former Member]

Hi,

We are getting error in a sender jms channel of PI 7.3 when connecting to MQ

A channel error occurred. Detailed error (if any) : java.lang.ClassCastException: class com.ibm.mq.jms.MQQueueConnectionFactory:library:com.sap.aii.adapter.lib@com.sap.engine.boot.loader.ResourceMultiParentClassLoader@6fb916fe@alive incompatible with interface javax.jms.TopicConnectionFactory:library:jms_api@com.sap.engine.boot.loader.ResourceMultiParentClassLoader@5cdeb323@alive<br> at com.sap.aii.adapter.jms.core.connector.ConnectorImpl.getTopicCF(ConnectorImpl.java:498).

This connection was working 2 weeks back. But now it is not working. We applied note 1751177 for this error but that did not help. However, receiver jms channel is working fine.

Kindly help in this regard.

Yes. those are present too.

Hi Ankit,

The error is incompatability of your MQ java Jars with PI jars. i think you need to check if there is problem in error in deploying the sap note.

This error was coming before i deployed sap note. SAP note didnt solve the issue. It was working fine two weeks back. Suddenly it is not working. Nothing was changed from PI side. Also, if jar files are wrong, receiver jms should not work. But that is working fine.
