Hi,
because EJB is implemented via Hibernate in the Background you can try this:
| public abstract class GenericDAOImpl implements
| GenericDAO {
|
| private static final Log _log = LogFactory.getLog(GenericDAOImpl.class);
|
| @PersistenceContext(type = Persiste
this is definitly NO bug.
Because Stateless SB have no "State" JBoss can recycle them after each call.
Regards
Peter

MySQL doesn't support Sequences. It looks like you use for your @Id generation
Sequences, which are not supported by your db. Change the
@GeneratedValue strategy to AUTO.

if you know your use-cases lazy-loading is not a big problem.
If you know exactly what to load use a facade with where the business methods
load what you want. Inside the BM use the EJB QueryLanguage like
from User u left join fetch u.companys as c left join fetch c.country where

to continue this example..
With this idea i would have a Contexts-Object with LocalThread attributes
(Context is a SFSB) which are initialized via a ServletFilter who
gets the Context from ServletContext, ServletSession and creates a new for the
Request Context. Furthermore i have a SessionListe
It is really not possible to share an EntityManager between SFSB, or would this
be only a problem if clustering?
So the conclusion would be something like a Command-Pattern, where
the Context SFSB is the Command "Executor" who has an EntityManager and my DAOs
only create Command Implementations
Is it possible to giveout the EntityManager of a STSB, if i have removed
Container-Isolation or would this end in a HorribleException?

if you do not want that JBoss create and drop tables every time your par is

EJB-CLASS-NAME/local, EJB-CLASS-NAME/remote

one the one hand you need to catch a HibernateException, on the other you will
not get an Exception until the transaction was commited. So you perhaps have to
