===============================

Cause

This is caused by an incorrect reference to the MQ classes on WAS v7 profiles that have been upgraded from 7000 or 7001.

Resolving the problem

To resolve this issue, you must do the following:

1. Start the application server.
2. Copy the attached Jython script into the profile_root/bin directory.

3. Use the wsadmin tool to run the Jython script that you have just created.
Open a command prompt and navigate to the profile_root/bin directory, then enter the following command (all on one line):

wsadmin -lang jython -f convertWMQRA.py -username <was admin id> -password <password>

4. Stop all servers in the profile.
5. Run the osgiCfgInit command from the profile_root/bin directory.
Note: The osgiCfgInit command resets the class cache used by the OSGi runtime environment.
6. Restart all servers in the profile.
