Hi Jerome,
Have you looked at the cairo Java binding that Soorya Kuloor has done?
http://www.cairographics.org/CairoJava
I have used this with success in my project. The binding is not quite
complete but there is enough there to get started. There are specific
classes to create GL surfaces. Even if it is not what you need it may
help you with your Java problems...
