Hello,
I am using some EJB3 session stateless bean with hibernate JPA integration on JBoss 5.1.0 GA. 

The EJBs are packaged within a JAR (containing the persistence.xml and *.hbm.xml mapping files) and each EJB defines a Session object injected with @PersistenceContext annotation. All works fine.

The problem raises when I try to make a hot deploy of the datasource. 

In this case I see that JBoss starts a new deployment of the datasource, of the persistence unit and the EJBs too but when I try to call an EJB I get a NullPointerException because the Session object wasn't injected.

This is the persistence.xml

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
             version="2.0">  
          <persistence-unit name="CFP-HibernateManager" transaction-type="JTA">
                         <description>Configurazione di JPA</description>    
            <jta-data-source>java:/jdbc/OracleCFP</jta-data-source>      
                <properties>
                  <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle9Dialect"/>
            </properties> 
          </persistence-unit>  
</persistence>

and the following is snipped code of an EJB

public class AnnoEJB extends CFPHibernateImpl implements AnnoRemote {

          @PersistenceContext(unitName="CFP-HibernateManager") 
          private Session sx;

Any idea is appreciated.

Thanks a lot
