Hi All,

i am using Eclipse Java EE IDE for Web Developers(Version: Indigo Release; Build id: 20110615-0604) which includes EclipseLink.

My Poject is working just fine in Eclipse, but i am not able to export it to a runnable jar. I always get Exceptions. Which JAR-Files i have to add to the classpath?

I dont understand the source of the problem. Could you give me a hint?

Regards,
Matthias

Where are you putting your persistence.xml? Is it in your meta-inf directory?

Are you using OSGi? What environment are you using and how is your persistence.xml on your classpath?

Also include your persistence.xml, is its header valid?
