    Persistence unit picks a few entity classes from module dependency but not all

    Prashanto Chatterjee Newbie

      I am trying to deploy a persistence unit where my entities are scattred across several JARs. Ideally I would like to add module dependencies to load all the entity JARs. Here is how I define my persistence unit:

      <persistence-unit name="SMGRPersistenceUnit">
      <jta-data-source>java:/jdbc/com/avaya/mgmt/avSysDB</jta-data-source>
      <jar-file>file:${jboss.home.dir}/modules/com/avaya/mgmt/cim/jpa/main/cs_cim_jpa.jar</jar-file>
      <class>com.avaya.security.securestore.entities.CSEncryptionKey</class>
      <class>com.avaya.security.securestore.entities.CSSecureStore</class>

       

      For my class entries I can see my entities getting deployed properly in twiddle:

      jboss.as:deployment=pluginMgmt.ear,subsystem=jpa,hibernate-persistence-unit=pluginMgmt.ear#SMGRPersistenceUnit,entity=com.avaya.security.securestore.entities.CSEncryptionKey

      jboss.as:deployment=pluginMgmt.ear,subsystem=jpa,hibernate-persistence-unit=pluginMgmt.ear#SMGRPersistenceUnit

      jboss.as:deployment=pluginMgmt.ear,subsystem=jpa,hibernate-persistence-unit=pluginMgmt.ear#SMGRPersistenceUnit,entity=com.avaya.security.securestore.entities.CSSecureStore

      jboss.as:deployment=pluginMgmt.ear,subsystem=jpa,hibernate-persistence-unit=pluginMgmt.ear#SMGRPersistenceUnit,collection=com.avaya.security.securestore.entities.CSSecureStore.csencryptionkeyCollection

       

      The JAR file that contains these entities has been added as a module dependency.

       

      However the entities defined in the JAR that is added as a jar-file entry does not get deployed unless I copy the JAR locally in the application. I find it really intriguing as to how it is working for one and not working for the other . Even if I comment the jar-file entry and try to use a class entry it does not work for the cs_cim_jpa.jar entities.

       

      Is this a known issue? Any guidance on how to proceed will be deeply appreciated. Ideally I want to be able to define module dependencies as we have a pluggable architecture and so the entities can be defined in separate JARs.

          I am migrating my applications from JBoss AS 6 to JBoss AS 7.1.1.Final. Presently I am just trying to deploy an EAR that only houses the persistence unit.

            You can't have those jar files outside of the deployment packaging. The spec states:

             

            JPA2 spec, section 8.2.1.6.3

             

            One or more JAR files may be specified using the jar-file elements instead of, or in addition to the

            mapping files specified in the mapping-file elements. If specified, these JAR files will be searched

            for managed persistence classes, and any mapping metadata annotations found on them will be pro-

            cessed, or they will be mapped using the mapping annotation defaults defined by this specification.

            Such JAR files are specified relative to the directory or jar file that contains[82] the root of the persis-

            tence unit.[83]

              When I started building my persistence unit I was bundling all the requisite JARs together in the application. It was just by accident that I discovered that a few entities were getting picked up from module dependencies. Is that something by accident or is there some configuration that is aiding this?

               

              Since we have a pluggable architecture it would work in my favor if I am able to let extensions drop their entity JARs in their own modules.

               

              Here is my deployment structure:

              <jboss-deployment-structure>

                          <!--    <module name="deployment.SMGRPersistence.ear.SMGRPersistence.jar" />    -->

                              </dependencies>

                  <resources>

                      <resource-root path="pan_plugin_frmwk_Manager.jar" />

                  </resources>

                      </deployment>

                     

                      <sub-deployment name="pan_plugin_frmwk_Servlet.war">

              </jboss-deployment-structure>

               

              And here is my persistence unit definition. There are some old properties using which we got it working when migrating from 4.2.3 to AS 6.

                The entities that I have defined under 'class' are getting picked from module dependency <module name="com.avaya.mgmt.securestore" export="true" />.
