    Hibernate Version Conflict in EAR File

    virgulino ferreira Newbie

      Hi People,

      I have an EAR file that contains hibernate-3.2.5.jar in the root, by my WAR file that is packaged into this EAR is using hibernate version of lib directory of the JBoss AS. How can I do the WAR uses the hibernate of EAR instead of that of lib directory of Server?

      Thanks!!

          Declare a loader repository for your app. To do this, in you META-INF/jboss-app.xml file (within the EAR file), add this entry:

          <jboss-app>
           ...
           <loader-repository>my.loader:loader=MyLoader</loader-repository>
           ...
          </jboss-app>


          You loader repository name is an MBean name and you can name it any name that follows MBean naming conventions.

            My jboss-app.xml contains this code:

            <jboss-app>
             <loader-repository>vigisus:loader=spiv.ear</loader-repository>
            </jboss-app>
            

            I'm beginner in enterprise applications and I'm confused with this configuration.

              This configuration helps you configure a classloader for your application. This way you can use your own version of libraries (jars) instead of using the ones that are shipped in JBoss. More details can be found at :

                I tried to configure it like this article, but it still doesn't work. I try too delete hibernate libs from lib directory of JBoss to assert that it will not be used. But I get follow errors:

                  Do not delete the jar files from the server's lib folder. Post the contents of your jboss-app.xml, where you have configured the classloader for your application. Also post the exception stacktrace when you deploy your application with these configurations. In your ear file which are the hibernate jar files that you have and also where are they placed in the ear?
