I have knowledge in java and wish to start game development is it better to use lwjgl (i cant use libgdx because of errors)

or just use eclipse without any game library

It depends how good you are with game programming already. If you are completely new to it, I would recommend you to just make simple games with just Java. OpenGL programming can be too much of a distraction and put you off game programming completely.

It's generally not easy to jump straight into OpenGL.

Here is a starter tutorial from our very own GD.net:

thx

I took a longer look at his tutorial series, and it seems to be.. rushed. Sorry about that.

This series may be better:

It does look more complicated, but you can always just ask questions here on gamedev.net forums.

Make sure if you do, to link to the tutorial page when you are explaining your problem, as it will help get quick answers. :)
