    Packaging Hibernate Mapping Files and persistence.xml

    Nick Jones Newbie

      Hi.

      We're moving our code base to EJB3 on JBOSS AS 4.2.1GA. We want to stick with Hibernate but use the @PersistenceContext annotations to inject the sessions.

      The problem we're having is on deployment, it seems like the Entities are being deployed twice which is causing a DuplicateMappingException

      Two of us have sat down and made sure we aren't duplicating mappings in our codebase and that the deployed jars aren't packaging files in an incorrect fashion.

      Here is our persistence.xml

      <?xml version="1.0" encoding="UTF-8"?>
      <persistence xmlns="http://java.sun.com/xml/ns/persistence"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      Does anyone have any advice on why the mappings might be occuring twice (Apart from the obvious mapping and packaging errors that we have checked)?

      Thanks for your time
      Nick.

          The duplicate mapping seems to be happening only for this class

          com.pioneer.riskbudgeting.dao.accesscontrol.hbm.ProtectedObjectTypeHTO


          I would search for the occurences of this class in all my mapping files and see if its been mapped more than once.

            Hi thanks for the reply.

            ProtectedObjectTypeHTO is just the class that is encountered first in the mapping, we changed the order of the mappings to check this. We still receive the same error just with a different class.

            So there could be duplicate mappings but if so its for all the classes.

            Thanks
            Nick.

              I haven't tried using the mapping-file element in any of my applications, yet, so i might not be of great help. Could you try adding the exclude-unlisted-classes attribute to the persistence.xml:

              <?xml version="1.0" encoding="UTF-8"?>
              <persistence xmlns="http://java.sun.com/xml/ns/persistence"

               <mapping-file>com/pioneer/riskbudgeting/dao/riskfactorschema/hbm/riskfactorschema.xml</mapping-file>
               <mapping-file>com/pioneer/riskbudgeting/dao/statistics/hbm/statistics.xml</mapping-file>
               <mapping-file>com/pioneer/riskbudgeting/dao/strategyattribute/hbm/strategyattribute.xml</mapping-file>
              
              <exclude-unlisted-classes/>
              
               </persistence-unit>
              </persistence>


              Also, can you post the output of the following steps:

              - From the command prompt, go to the folder containing your persistence archive (the 20.rb-ejb.jar).
              - Run

              jar -tf 20.rb-ejb.jar


              Post the output here. That will show us how the jar is packaged.

                Hi Thanks for your help. I've got a solution for this problem.

                The culprit was here the file below,

                <mapping-file>com/pioneer/riskbudgeting/dao/accesscontrol/hbm/accesscontrol.hbm.xml</mapping-file>
                
                as described here http://docs.jboss.org/ejb3/app-server/reference/build/reference/en/html/hibernate.html
                any files with extension hbm.xml in the classpath will be added to the hibernate config. So while we changed the order of classes within accesscontrol.hbm.xml to check invidual classes weren't duplicates, all classes in there were being duplicated.

                Perhaps if the file is listed in the <mapping-file> of persistence.xml it shouldn't be then loaded again by JBoss.

                Cheers
                Nick.
