there are serveral sub chapters. Like Java 3D, Image I/O, etc. "Image I/O" for example found its way to the J2SE with 1.4.0, which is fine.
When you click on "Java 3D" there's no mention about OpenGL for Java, in short "Jogl". I think this is a pity, because surely people interested in Java and 3D will take a look there (I did) - and surely not all of them need the "Java3d" package.
Only with some luck I found to the Jogl project pages at Java/net/games. But I know there are many people who don't think OpenGL is a game's chapter only. So they will hardly look into the java/net/games project's pages. :-)
Some guys here work at SUN. Maybe they could, or maybe we could, try to convince the webmasters of the central Java-Media-pages to include a link to Jogl?
Or is it too early, yet?
However, please bear in mind that many projects leads have to take decissions with respect to a long term time shedule - so I don't think it's too early. The faster they learn about the fact that OpenGL is ready for Java, the better!
