Firstly, truncated, badly formatted, and incomplete stack traces are [b]not[/b] helpful - in fact, what you posted is pretty much useless, so please paste in everything and check it before you post.
Secondly, I don't understand what you did with Eclipse - you said originally it worked in Eclipse, so exactly what did you do differently?
Thirdly, please post the entire output from your console (I am assuming you got a stack trace).
