jBoss and Hibernate

[marcelk1607]

Hello!

I am doing my own hello world jBoss EJB application.
I've got derby running, have a connection to it. have a EJB remote.

However when doing a query I get classnotfound HibernateQueryException.

Why Hibernate? Do I need Hibernate to do queries?

Hi!

Where do you see the exception? In your EJB or in the client side? Please provide more details about your app.

JBoss uses Hibernate internally to perform all EJB3 database access. Does your app contain hibernate JARs?

Best regards

Wolfgang

Exception in thread "main" java.lang.reflect.UndeclaredThrowableException
 at $Proxy2.findMedewerker(Unknown Source)
 at nl.capgemini.inzetmanagement.client.Client.main(Client.java:27)
Caused by: java.lang.ClassNotFoundException: org.hibernate.hql.ast.QuerySyntaxException

This happens when i use this code:

@Override
 public Medewerker findMedewerker(int id) {
 Query createQuery = entityManager.createQuery("SELECT m FROM medewerker m");
 Collection<Medewerker> result = createQuery.getResultList();
 System.out.println(result);
 return null;
 }

Ths is what I put in my remote bean.

So do I have something missing in my libs? Do i need hibernate in the libs dir?

Also I am running the client app in Eclipse, maybe I need hibernate there?
I am confused sorry.

Which version of JBoss AS are you using? I found the QuerySyntaxException
in common/lib/hibernate-core.jar, so it should be available.

Could you post your JAR or EAR file that contains the EJB? Use: "jar -tf xxx.jar" where xxx.jar is the name of your JAR (or EAR) file.

Also, is the code that you posted from and EJB3 session bean? If so, where are the entity beans located relative to the session bean? The stack trace suggests that you are attempting to access the entity beans remotely...

Sorry, already solved it, i didnt have the right jars.

Thanks anyway!
