Something like this ? /myapp/ATMOps/* ---> REQUIRES_NEW /myapp/AccountOps/* ---> REQUIRES /myapp/SimpleOps/* ----> NOT_SUPPORTED /myapp/FlushOps/* ---> NEVER // probably not....
successful call to: /myapp/ATMOps/completeTransfer ----> COMMIT /myapp/AccountOps/completeUpdate ----> COMMIT redirect to: /myapp/ATMOps/handleError ---> ROLLBACK /myapp/AccountOps/handleError ---> ROLLBACK etc. 1. Determine the URL 2. Lookup the URL/Transaction Map (Default to NOT SUPPORTED) 3. A. If REQUIRES lookup HTTP Session and grab UserTran. If does not exist, create one and start. B. If REQUIRES_NEW, set flag for Nested tran in session, acquire new user tran and start. C. If NEVER, lookup tran in session and if tran is present and active, throw exception. more rules here.... //Nicholas --- Bill Burke <[EMAIL PROTECTED]> wrote: > I say make it a filter.
