Eclipselink problem in a javase project

I am getting this error when I am running my eclipselink project.

Any ideas? Why would eclipselink need something from jboss? What jboss jar do I need. I would use open jpa, but for some reason after quit a few persists from my app it starts giving a bunch of stackoverflow errors.

I did not realize you added this answer: you should make it a comment to my answer if you want me to get notified (or you could edit your own question and add this information)

My point was: probably a config file somewhere still specifies a web server, even though your project is supposed to be standalone: at execution time, this config file is still read and acted upon.
