in my search at my ragdoll/ physics problem I’ve created this class:

(the important code is just stolen from the tutorials :p)
now when I call the code with this:
[java]Material mat1 = new Material(assetManager, “Common/MatDefs/Misc/SolidColor.j3md”);
mat1.setColor(“m_Color”, ColorRGBA.Blue);
ragdoll=new simpleRagdoll();
ragdoll.setMaterial(mat1);
ragdoll.setLocalTranslation(new Vector3f(0, 20, 0));
bulletAppState.getPhysicsSpace().addAll(ragdoll);
rootNode.attachChild(ragdoll);
[/java]
it does nothing.
I can’t see my pretty ragdoll and when I keep my camera at that ragdoll’s location it seems that physics on it doesn’t work.
So there should be something wrong with my code: it is not blue and it’s physics aren’t working.
someone that can spot my stupid mistake?
