A way to get all the persistence units names with EJB 3.0 ?

[olvin]

Hello,

Is there a way to get all the persistence units names installed in JBoss 4.0.5 ?

So, I have put this in my persistence.xml for all persistence units to add JNDI references to the persistence units :
""

But in a session bean, how can i get all the persistence units names without knowing them ?

Thanks,

Olv
