    EntityManager can't see mapped classes in jar file

    Bret Wortman Newbie

      I have a set of annotated entity classes that live in a common.jar file.  I'm able to build a .war file which references this common.jar, and to generate ddl via hbm2ddl.  When I deploy the resulting .war file, though, the EntityManager isn't able to find mappings for any of my classes resulting in errors like the one below.


      I have tried including the .jar within the .war, placing the .jar into the server/default/lib directory, referencing it from another common location, and many variations along the way all without success.


      Any pointers would be very, very welcome.  I had thought I was home free when the build succeeded but obviously I'm still missing a piece somewhere. 


      Note:  If I move the source for these classes into the .war project, then it works perfectly, but I'd like to keep these separate for various reasons.
