A wild guess...
Have you somewere in your entities annotated either a collection of Longs, or a long field with any of the relationship annotations: @ManyToOne, @OneToMany etc.?
That is what I thought before I posted here. But I double checked. Nope, no primitive long or Object type Long.
What is wierd is, I have gotten this project to deploy on another machine. But it won't on this machine.
My next step will be to do another project. If that doesn't work, I guess I will copy the Ecplise and JBoss directory from my work machine to this machine at home.
Thank you. I am still looking for an answer if anyone else may have ran into this problem.
Problem fixed. :D
