The ARB has set up a group working on official OpenGL
bindings proposal for Java. See www.opengl.org news
page.
There is also a announcement of a VRML browser source
written in Java, from the same coder in Graz who wrote
VRWeb and contributed a lot to Hyper-G.

I am looking for a Linux tool to generate Java source
from C. I am aware of C2J/C2J++. What I need would
have to be used repeatedly - the code will be
maintained in C. Changing the C code once to match
converters restrictions is feasible.
Short of hacking C2J++ - any recommendations?

Nah, this is Java to C.

I gave Mauve a quick try (with a test harness for my

non-GPL'ed Java software.

Is this using your AWT? I gather from Kaffe's source
While doing something OpenGL related (interleaved
float/int arrays) I stumbled over a detail of the
native float Float.intBitsToFloat(int)
implementation: that all IEEE 754 NaN values (2^23)
are mapped to Float.NaN.
Might be worth a Mauve check?

How do you prevent somebody taking a (L)GPL'ed or Open

I must be missing something here. What exactly is jnilink?

I do not think that adding tags is the right thing
to do, ultimately. I have to dig out some weave/tangle
references with respect to SGML, but for the moment
just for SGML: www.sgmltools.org

SGML should be used instead of HTML. The most con

Mid term and long term, adding JNI support to gcj would be the
