I posted a question about a problem a was having with a EJB application i was migrating from WAS6 to WAS8.5.5, here is the link:
Message selector on MDBean not working properly
And I found that a had a prior version of WMQ (v6), so i upgraded that version to v7 and my application worked.
My question is, isn't WAS 8.5.5 suppose to support prior version of WMQ ?
