I have to use a jpa project on one of my projects, but I'm having this error once I create an entitymanager and call persistencecontect in my sessionbean:

@Stateless
public class Biblio implements BiblioLocal {
 @PersistenceContext(unitName="BiblioJPA")
 private EntityManager em;
    /**
     * Default constructor. 
     */
    public Biblio() {
        // TODO Auto-generated constructor stub
    }

 @Override
 public String succes() {
  // TODO Auto-generated method stub
  return " beta";
 }
 public void toevoegenBoek(){
  Boeken boek = new Boeken();
  boek.setTitel("harry P.");
  boek.setAuteur("rowling");
  em.persist(boek);
 }

}

My servlet (which calls a method from this sessionbean) won't load anymore and gives me this very long error of which i don't understand anything. Any ideas? (without the entitymanager and persistencecontext my servlet does load, but then i'm not able to call any functions related to the jpa!)

Thanks!

The error i get when running the servlet:

The error in my console (in eclipse)

Edit:

persistence.xml

mysql-ds.xml

    <metadata>

    </metadata>
  </local-tx-datasource>
</datasources>

Well, it looks like a JDNI lookup problem ("JPA is not able to lookup the datasource").

Could you please show your persistence.xml and your xxx-ds.xml configuration files.

Ok, now, this error looks weird (from the console output):

org.xml.sax.SAXParseException: cvc-complex-type.3.1: Value '2.0' of attribute 'version' of element 'entity-mappings' is not valid with respect to the corresponding attribute use. Attribute 'version' has a fixed value of '1.0'.

It seems you are using Object/relational Mapping Files and I'm afraid you're facing HHH-5310 which is currently not fixed. Can you do without Object/relational Mapping Files?

I downgraded to Eclipse galileo and it started working, I don't know what exactly the problem was, but that fixed it for me.
