I don't like having to ask for help but I'm a little stuck now.
Hi Crackers!
I forgot to check in the ode impl today :// - should be working now
But you should either way use the (old) jmephysics from sourceforge as the new one on java.net is not complete yet (most importantly joints are still missing). I will post a sticky note on it here.
As you even figured out (correctly as it seems btw) how to configure the new jmephysics you will have no problems using the old jmephysics from that cvs location:
:pserver:anonymous@cvs.sourceforge.net:/cvsroot/jme-physics

Okay, thanks!
