    Using plain JPA/Hibernate4 in AS 7 cannot find entities

    lostiniceland Newbie

      Hello

       

      I have a little demo-project and I am trying to use JPA withing AS7. I am not trying to use Hibernate 3 or any special dependecies, just the modules that the server uses by default.

       

      When I try to deploy my WAR then I am getting a ClassNotFoundException telling me that my domain-classes cannot be found. I read the article about ClassLoading and for a war-deployment every jar within the lib-folder is added to the classpath. I checked my war-file (produced by maven) and all dependencies are available.

      What I found strange is the fact that when I remove the @PersistenceContext(name="bikeviewer) annotation I dont get this error (but my application doesnt work) even though I provide a persistence.xml which also maps this particular class.

       

      It shouldnt be necessary to provide the proprietary depencies-section in the manifest since I want to use the default hibernate-module...or am I wrong here?
