Try to make an SSCEE (Small Self Contained Compiling Example), showing what you have until now, and post that.
I just helped another guy, Move objects(sphere) by click on buttons(right,left,top,bottom) using java3d, what he posted is almost a SSCEE, you can also experiment with that (the ball is rotated by the mouse, try to make it rotate at any location (what it does by the way)).
Then explain what you didn't get working.
