    PersistenceContext is null after datasource hot deploy

    David Visicchio Newbie

      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
