      Hi all, I need your great help

      I have the following entities each in individual jars in JBoss 6.1.0

       

      jar1.jar contains

       

      @Entity
      @Table(name = "Table_a")
      public class EntityA {
         @id
         @Column(name = "id_a")
         private String idA;
      
        ... getter and setter
      }
      
      

       

      persistence.xml

       

      <?xml version="1.0" encoding="UTF-8"?>
      <persistence version="2.0" 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">
        <persistence-unit name="datos1PU" transaction-type="JTA">
          <provider>org.hibernate.ejb.HibernatePersistence</provider>
          <jta-data-source>java:/datos1DS</jta-data-source>
          <class>example.EntityA</class>
          <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
          </properties>
        </persistence-unit>
      </persistence>
      

       

      jar2.jar contains

       

      import example.EntityA;

       

      @Entity

      @Table(name = "table_AA")

      public class EntityAA {

       

         @id

         @Column(name = "id_aa")

         private String idAA;

       

         @ManyToOne()

         @JoinColumn(name = "id_a")

         private EntityA a;

      }

       

      persistence.xml

       

       

      <?xml version="1.0" encoding="UTF-8"?>
      <persistence version="2.0" 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">
        <persistence-unit name="datos2PU" transaction-type="JTA">
          <provider>org.hibernate.ejb.HibernatePersistence</provider>
          <jta-data-source>java:/datos1DS</jta-data-source>
          <jar-file>jar1.jar</jar-file>
          <class>example.EntityAA</class>
          <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
          </properties>
        </persistence-unit>
      </persistence>
      

       

      to deploy generates this error

       

       

      ERROR [org.jboss.kernel.plugins.dependency.AbstractKernelController] Error installing to Start: 
          name=persistence.unit:unitName=jar2.jar#datos2PU 
          state=Create: org.hibernate.AnnotationException: @OneToOne or @ManyToOne on example.EntityAA.a references an 
          unknown entity: example.EntityA
      

       

       

      I can not packaged the jar in an EAR because I need the definition of these entities are available for other applications (eg guvnor drools)

       

      any idea
