Hi,

I have a class which tries to look up a Queue/QueueConnectionFactory and then submits message.
The code works fine with Weblogic9.x but throws the following exception in Webshpere6.1.
com.ibm.mq.jms.MQQueue incompatible with javax.jms.Queue

Code:


Any help would be appreciated.

Ideally this code should work without any exception, because com.ibm.mq.jms.MQQueue implements javax.jms.Queue. please share full exception stack trace.

Thanks,
Ankit

I found the reason by opening a PMR with IBM.

Reason: If a .jar file contains a Java Extension class (javax.*.class) file which is also provided by WebSphere, then it must not be included in your Shared Library or application, or else a ClassCastException or similar error will occur. If the javax.*.class is NOT provided by WebSphere Application Server, then feel free to use that .jar in your application or Shared Library.
