there is a better/faster option available
and that is GCC's GCJ (or was it GJC)
GCC's Java Compiler (it produces native code)
it compiles both .java and .class to native code.
and since OS4 will get GCC 3.2+ GCJ would be a 'simple'
way to execute java code on the amiga until DE is
available.
otherwise, why not contact Holger about his JavaVM
which apparently was just about ready (Hyperion?).
