Hi,
I have only little experience with Maven. Currently, I'm working on a project with JPA. It's a desktop application without Application Server. I added the hibernate-entitymanager-3.4.0.GA.jar to the dependencies (all corresponding dependencies are resolved by Maven). My JUnit tests concerning Hibernate and Entities run fine with no errors (so I guess that Maven principally runs fine). Unfortunately, I get the an error (see below) when I am creating a jar file and run the program afterwards. As I can see, of course, the javax.persistence jar provided by the ejb3-persistence.jar is obviously missing. But I don't know how to fix the problem. When I'm running the program as a simple Java Desktop App, everything is fine. If you could provide me any more information, that would be great. Thanks in advance.
