AS 4.0.5 I have a need to configure both a web app and an MDB to run in their own execute thread pools. The web app is a high-use app and I want to keep it's usage from affecting the availability of the other apps deployed to the server by segregating it on its own thread pool. The MDB is sending mail though our system which periodically has issues causing all the mail connections (MDB threads) to hang, so I'd also like to segregate this one off. Is it possible to configure either of these? Thanks.
