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)
at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:83)
at managers.PersonBean.getEM(PersonBean.java:19)
at managers.PersonBean.findThemAll(PersonBean.java:25)
at bozickawar.SessionBean1.updatePersons(SessionBean1.java:51)
at bozickawar.SessionBean1.init(SessionBean1.java:87)
at com.sun.rave.web.ui.appbase.servlet.LifecycleListener.attributeAdded(LifecycleListener.java:350)

Any ideas?

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

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.

No, abbreviations like "Srini Jcl" are not acceptable. Please go back to "my profile" and correct your displayed name.
 
It is sorta covered in the JavaRanch Style Guide.
