Finding the current persistence unit for the current EntityManagerFactory (2 answers)

Closed 5 years ago.

How do you get the name of a persistence-unit in Java? I have a persistence.xml with many units, so I want to control which unit is used to create my EntityManager.

There's method like getPersistenceName or smth? I have searched for a while but did not find anything useful.
