Hi, I've been investigating the use of JCA resource adapters running under WebSphere v5. I've been able to muddle my way through up to this point (no thanks to the dismal documentation from IBM!) and have managed to get a test connector working properly, apart from the connection pooling element. WebSphere is managing the connection pooling fine (or so it would seem) and creating the connections as required. But, if I have the maximum connections set to 2 for example, when I send in a third request, WebSpere times out telling me that there are no more connections available. It seems that the first two connections that are created, never get returned to the pool and get lost in some sort of void, never to be seen again. Am I doing (or not doing as the case may be!) something wrong? Is there something I should be doing to get the created connections returned to the pool? Any help on this would be greatly apprectiated!! Thanks, Kev.
