PersistenceException : NPE

Hi,

Given my persistence.xml below :

Code:

<?xml version="1.0" encoding="UTF-8"?>

<entity-manager>
    <name>TimeFaces</name>

    <class>example.model.a</class>
    <class>example.model.b</class>
    <class>example.model.c</class>
    <class>example.model.d</class>
    
    <provider>org.hibernate.ejb.HibernatePersistence</provider> 
 
    <properties>
        <property name="hibernate.ejb.cfgfile" value="/hibernate.cfg.xml"/>
    </properties>
   
</entity-manager>

I got the following error :
[junit] javax.persistence.PersistenceException: java.lang.NullPointerException
[junit] at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:97)

What's wrong with the file above ?

Thanks for any help/suggestion,
nusa.

Well, I know this bug used to exist, but the released version doesn't have it. Are you sure you're using the beta1 version?

I just replace all hibernate jars from JBoss-4.0.3RC1 with the beta1, and it works. Merci Emmanuel.
