Hi,

Assuming I only have one persistence unit in persistence.xml.

How to get persistence unit name from persistence.xml programmatically?

Please advise.

Regards,
Jap.

Hi,
it appears it is not (currently) possible:

If you vote and/or comment on the issue explaining a good use case you could get more chances for this to be implemented.

Hi,

If you are using JBoss, it is possible to find out what the persistence units are from calling:

Code:

PersistenceUnitRegistry.getPersistenceUnits();

Cheers,

Andy

Hi,

Thanks for the info. However, I'm using Tomcat 5.5.26.
