Java Persistence in a Desktop Application

188 100+
Hi all,

Am trying to create a Java Desktop App that uses Java Persistence in Netbeans.
The database is MS Access but I tried with Mysql and got the same error.
When I run the app( Create the entity manager), I keep getting the following...

  1. Exception in thread "AWT-EventQueue-0" javax.persistence.PersistenceException: No Persistence provider for EntityManager named ReceiptingPU:  The following providers:
  2. oracle.toplink.essentials.PersistenceProvider
  3. oracle.toplink.essentials.ejb.cmp3.EntityManagerFactoryProvider
  4. Returned null to createEntityManagerFactory.
  6.         at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:154)
  7.         at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:83)
Here is the persistence.xml

  14.     </properties>
  15.   </persistence-unit>
  16. </persistence>
I have the toplink library correctly in the class path. Any one with some light please?
