Martin,
While the app I'm currently working on is a web-based app, I have an
explicit dependency declare for the persistence API. Whether it is
necessary, I'm not sure, but it's in the POM. So, I thought I'd reply
with it for you.
<dependency>
<rgroupId>javax.persistence</groupId>
<artifactId>persistence-api</artifactId>
<version>1.0</version>
</dependency>
I hope this is helpful,
Dave

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.
