No Persistence provider for EntityManager named.....

[Gaya Georgieva]

Hello, everybody,
a pleasant place you've got.
Here is my problem - I'm trying to fill a visual JSF table with entries from a table of a MySQL database. but I get the following exceptions:

javax.persistence.PersistenceException: No Persistence provider for EntityManager named BozickaPU: The following providers:
oracle.toplink.essentials.PersistenceProvider
oracle.toplink.essentials.ejb.cmp3.EntityManagerFactoryProvider
Returned null to createEntityManagerFactory.



at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:154)

Any ideas?

Can you paste your persistence.xml

[Bear Bibeault]

"Ga Ga" and "Srini", please check your private messages for an important administrative matter.

No, "Srini M" is no better. Abbreviations like that are not acceptable; please correct your displayed name again.

[Srini Mutpur]

It is not able to find the Persistent unit with the name "BozickaPU".
Once check your persistence.xml, is there any persistent unit with the name "BozickaPU".
And make the changes accorndingly.

[Campbell Ritchie]

No, abbreviations like "Srini Jcl" are not acceptable. Please go back to "my profile" and correct your displayed name.
