There's a JOGL renderer, it's just not supported or maintained very well.

I do what I can, it is maintained and you know it, it is supported, lots of basic test cases work with it. There are a few remaining bugs in the JOGL renderer but it works fine.
Kevglass, you should read the wiki, especially the introduction :
jME was built to fulfill the lack of full-featured graphics engines written in Java. Using an abstraction layer, it allows any rendering system to be plugged in. Currently, both LWJGL and JOGL OpenGL bindings are supported.
