The reason i ask for why the context is not being active is, that i wanted to use a transaction scoped EM for my data access methods(query db) too. I want the persistence context to be cleared or closed everytime i leave my "outermost" business or a data access method to prevent lazy loading in a different layer. My problem with the transaction scope is, that i can't use it in the data access methods, since i don't want to open a transaction for ever db access. Shouldn't the transaction scope behave like a persistence context within an ejb? How do you handle that kind of problem? Am 30.10.2012 12:27 schrieb "Christian Beikov" <c.bei...@curecomp.com>:
