    OpenJPA in JBoss EAP 6.1

    Geoffrey De Vylder Newbie

      I am trying to use JPA in a project using OpenJPA and JBoss EAP 6.1

       

      Following the tutorial at http://middlewaremagic.com/jboss/?p=1991 I have:

       

      • added the module to my modules folder.
      • Added these items to my 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="MyPU" transaction-type="JTA">
      
      
              <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
      
      
              <jta-data-source>java:/MyDS</jta-data-source>
      
              <class>... my classes .. </class>
      
      
              <properties>
                  <property name="jboss.as.jpa.providerModule" value="org.apache.openjpa"/>
                  <property name="jboss.as.jpa.adapterModule" value="org.jboss.as.jpa.openjpa"/>
                  <property name="jboss.as.jpa.adapterClass" value="org.jboss.as.jpa.openjpa.OpenJPAPersistenceProviderAdaptor" />
      
                  <property name="openjpa.DynamicEnhancementAgent" value="false"/>
                  <property name="openjpa.RuntimeUnenhancedClasses" value="supported"/>
              </properties>
          </persistence-unit>
      </persistence>
      

       

      • Created a jboss-deployment-structure.xml in my WEB-INF/ folder and put in:

       

      <?xml version="1.0" encoding="UTF-8"?>
      <jboss-deployment-structure>
          <deployment>
              <dependencies>
                  <module name="org.apache.openjpa" />
              </dependencies>
          </deployment>
      </jboss-deployment-structure>
      

       

      When I deploy my application the following error is displayed:

       

      14:22:13,179 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-1) MSC000001: Failed to start service jboss.module.service."deployment.myapp-web-services-0.0.1-SNAPSHOT.war".main: org.jboss.msc.service.StartException in service jboss.module.service."deployment.myapp-web-services-0.0.1-SNAPSHOT.war".main: JBAS018759: Failed to load module: deployment.myapp-web-services-0.0.1-SNAPSHOT.war:main

      Any ideas on what I can do to resolve this error?

          kpagan Newbie

          I see in your persistence.xml you have

           

          <property name="jboss.as.jpa.providerModule" value="org.apache.openjpa"/> 

          <property name="jboss.as.jpa.adapterModule" value="org.jboss.as.jpa.openjpa"/>

           

          So, actually there is a reference to the org.jboss.as.jpa.openjpa module in your application. Do you really need to define the jboss.as.jpa.adapterModule?

          In the article you mention this is not defined. Only the x.x.x.providerModule is defined.

           

          But if you really need it try to set it to "org.apache.openjpa".

          P.S. I wouldn't recommend to use the openjpa-all-2.x.x.jar for you module. This include the jta.jar inside and it was causing me great trouble to setup the JTA transaction manager.

          Use a plain openjpa-2.x.x.jar and set dependecies

           

              <module name="org.apache.commons.lang"/>
             <module name="org.apache.commons.collections"/>
             <module name="javax.persistence.api"/>
             <module name="javax.transaction.api" export="true" />
             <module name="javax.validation.api"/>
             <module name="org.apache.log4j"/>
          • 2. Re: OpenJPA in JBoss EAP 6.1
            kpagan Newbie

            Actually, I tried to upgrade from JBoss EAP 6.0.1 to JBoss EAP 6.1.0 and I run to the same problem. My proposed solution didn't work.

            I found a similar question and a post that was suggesting to install the adapter module manually. The link is https://community.jboss.org/message/834599#834599

            I tried that and the application was deployed successfully but then when trying to test the application many exceptions where thrown like

             

            Caused by: <openjpa-2.2.1-r422266:1396819 fatal user error> org.apache.openjpa.persistence.ArgumentException: The type "class com.intrasoft.sw.jpa.admin.AdmBrokerRightsTPK" has not been enhanced.
            

             

            The full stacktrace is very long but this is the root cause of the problem.

             

            I read the OpenJPA manual in order to enhance my entities and tried again.

            This time I got another error. The full stacktrace is:

            This build was run successfully on JBoss EAP 6.0.1. Something changed in JBoss EAP 6.1.0. Is there any reference or migration guide that I can get some information?

             

            So far I haven't find anything in official docs.

              I finally managed it to work!!!

               

              After following this guide Re: Openjpa on JBoss EAP 6.1.0 with AS 7.2.0 I set in the persistence.xml the property:

              <property name="openjpa.MetaDataFactory" value="jpa"/>

               

              See the documentation at http://openjpa.apache.org/builds/2.2.2/apache-openjpa/docs/manual.html#ref_guide_meta_factory

              Setting the value jpa as it is without parameters it worked for me.

              Otherwise you may need to specify the jar where to scan for entity classes like

              <property name="openjpa.MetaDataFactory" value="jpa(ClasspathScan=my-project-jpa-entities.jar)"/>

               

              My final persistence.xml is:

               

              <?xml version="1.0" encoding="UTF-8"?>
