> Hi,
> I'm trying to develop an application in JEE using maven and Glassfish, but
> I have a problem that I can't solve by myself.
> I'm doing an appclient make a request for a Stateless Session Bean, well
> I'm getting the answer at first request, but if I try to do a second request
> I got an Exception saying my EntityManager is closed, but I'm not closing it
> in my hard code. After if I try to do a third request I get a right answer,
> if I try fourth the exception appear again, and so on. What I mean I'm
> getting correct answer on odd request but on even request I'm getting that
> exception.
> This is the Exception I'm getting:
