Hi People,

I am looking for a solution to my problem for days but I didn´t find anything that could really help me.
In my app I am using JBoss 4.2.3 GA and EJB3.

What I need:
Allow that each customer of my system (Today 5 but more than 2000 sooner) have it own database (Can be the same database but diferent schema). I mean, use the same entities and sessions.

I tryied to create the entityManager inside my stateless session, but without success. Today I was deep inside the jboss code looking for the code that instantiates the EntityManager when I put the code

because I realized that if I found this code, I would be able to change the unitName programatically and force JBoss to instantiate the correct EM and then I wouldn´t have to change any session or entity code.

I beg anyone to give me a north, could be links, concepts or any kind of example. I would really apreciate that.

Thanks in advance.

I also forgot to say that what I´m trying to do is easy to do with pure hibernate. Only some configuration objects and it´s done. The problem is really when I enter the JBoss world, with it´s automagic way of instantiate the EntityManager...

so,

It seems that it is not possible...

Hi Ander,

it seems you are facing a problem like mine.

look at my proposed solution, however I'd like to ear from the hibernate guys if there are some critical drawback (ie in persistance cache or hibernate second level cache or in high concurrency ) that could come up in a long running env.

Ciao
