Check out BillboardControl. You can make a quad with some texture etc. BillboardControl will keep it facing the camera. I think this is what you asked… right?

material.getAdditionalRenderState().setDepthTest(false); ?
Note: the reason folks are reluctant to answer your questions is because you provide almost no information.
Past experience with every thread you’ve started has been something like:
You: short question
Others: variety of answers guessing what you need
You: telling them that they are wrong and it doesn’t work
20 messages later we finally figure out what you really wanted.
