No Persistence provider for EntityManager

[dheerajsega]

HI,
I have tried to test my application using Testng methods.
But my tests are failed and it returns the error::

javax.persistence.PersistenceException: No Persistence provider for EntityManager named...

Can anyone tell me why I am unable to test even when the persistence file is correct.

How can I solve this?

[loaone]

Hello

Thanx

Hi Loaone,

I suppose you will not get an answer if you recycle such old thread. Maybe your JBoss version and environment is also very different.

You should open a new thread and provide informations about your problem.
