Thor Lange commented on WFLY-5549:
----------------------------------

We experienced this same problem and even if our setup might be a little bit different the solution might work :-)

We have a setup where Hibernate classes are included in the application to be able to run HIbernate as JPA provider on both Wildfly and WebLogic. To be able to run on both servers with the exact same application we need to include dom4j.jar. However creating {{jboss-deployment-structure.xml}} in your META-INF you can make sure the dom4j classes from Wildfly is used when running on Wildly (as WebLogic does not understand the descriptor file it is just ignored when the application is deployed to that application server).

        </dependencies>
    </deployment>
