Hi, I am trying out Hibernate EJB3. I have no clue what the error I have is. I would thank a million for anyone who can shed any light. This is the error I have.


1) testUserSave(com.test.persistence.TuserTest)java.lang.VerifyError: (class: org/hibernate/ejb/AbstractEntityManagerImpl, method: throwPersistenceException signature: (Lorg/hibernate/HibernateException;)V) Incompatible argument to function
at org.hibernate.ejb.EntityManagerFactoryImpl.createEntityManager(EntityManagerFactoryImpl.java:37)
at org.hibernate.ejb.EntityManagerFactoryImpl.createEntityManager(EntityManagerFactoryImpl.java:32)
at com.test.persistence.TuserTest.testUserSave(TuserTest.java:65)

at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)
at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)




TuserTest.java:65 is this line


entityManager = entityManagerFactory.createEntityManager();


When I do this

entityManager = entityManagerFactory.createEntityManager(null);

This is what I got

There was 1 error:
1) testUserSave(com.test.persistence.TuserTest)java.lang.AbstractMethodError: org.hibernate.ejb.EntityManagerFactoryImpl.createEntityManager(Ljavax/persistence/PersistenceContextType;)Ljavax/persistence/EntityManager;

I am new to Hibernate EJB3. So it very much possible on the way I use Hinernate, I guess. I have heard from other developers that it is solid. So I would appreciate if anyone can point out what I should do to get over this. The version I use is

Hibernate Core 3.2.CR1

Hibernate Annotations 3.1 beta 9

Hibernate EntityManager 3.1 beta 7


This is the persistence.xml I used.

Thanks alesj. Can you elaborate? I think you are seeing what I do not. I did follow the examples and got the result. I am new to Hibernate and don't really know where to look when things go wrong. Thanks again.

Looks like you have some incompatible versions in your classpath or some weird JDK.
Are you sure you only have HEM beta7 HA beta9 (no older version) and the corresponding ejb3-persistence.jar?
Which VM are you using?

Thank you for your reply. I run jdk1.5.0_06, hibernate-annotations-3.1beta9, hibernate-entitymanager-3.1beta7 and the latest hibernate core. I deleted the libraries, reload them and rerun the test. However this is what I got:


1) testUserSave(com.test.persistence.TuserTest)java.lang.AbstractMethodError: org.hibernate.ejb.EntityManagerFactoryImpl.createEntityManager(Ljavax/persistence/PersistenceContextType;)Ljavax/persistence/EntityManager;

I am now even more confused. I included all the jars and those in the lib from those packages as well. Thank you if you can shed any light.

TuserTest use the old EMF API (ie pre beta7).

Thank you Emmanuel. I redownload all of the packages from Hibernate.org. I reload the libraries and rerun the test. This is what I got:

I think I learned something. I appreciate your help. For the current error, I am not sure if transaction was mentioned any where in the doc I read. Do we need to get transaction going to save objects? If yes, how do we do that? I didn't see anything on that in the doc.


Thank you

That's actually in the javadoc :-)

Thank you. I went back and read the doc and found it. I still can not get it working but I think I will slowly figure things out first. Thanks again.
