I recently ran into an issue when attempting to use JMS Adapter 6.1 with IS 6.5 and Developer 6.5. I could create and enable the JMS Adapter Connection, but got errors when attempting to use Developer to create an adapter service.
I searched Advantage fixes and found JMS Adapter 6.1 Fix 3. wM Support later indicated that Fix4 is now available.
Both appear to correct the problem.
