Free Java Development Environment (fwd)
Christian, here is a posting I made to our LUG recently. It includes
the Kore URL.

Subject: Free Java Development Environment
Recently, I have been looking around for free software
projects that support Java development. I am particularly
concerned that Sun's Java is *not* free. Well, it seems
that there are already some projects underway. Here are
some notes I have collected from various sources:
Java Open Language Toolkit
The JOLT project is aimed at providing a freely available and
redistributble implementation of Sun's Java language and tools.
Kaffe the free Java Virtual Machine
The current version available is 0.9.2, it is compatible at the
bytecode level with Sun JDK 1.1.3. However a few features are still
lacking on the current version.
Guavac is a new standalone compiler for the Java programming language.
It was written entirely in C++, and should be portable to any platform
supporting Gnu's C++ compiler or a similarly powered system.
Glynn Clement's "kore" - a free set of classes to replace Sun's
java class libraries. These are needed, in addition to Kaffe (or
Per Bothner's upcoming Java gcc enhancements), in order to create
a 100% free Java implementation.
Send a message containing "subscribe" in the body to
firstname.lastname@example.org to sign up.
The kore package itself is available at:
I also dug up a reference for Per Bothner's Java gcc project mentioned
above, although it seems that whatever cygnus is doing, they are
keeping it to themselves for now:
Also, see this article on Per's first Java/gcc program:
(Keep in mind that article is from way back in June.
I don't have any idea how far they are now.)
In summary, it looks like it is worthwhile to start writing GPL'd
Java code right now, as very soon the free development environment
to support it will be in place.
If you're very brave, you might try Kaffe + Guavac + Kore as your
development environment, but it seems from recent mail traffic on the
Kaffe list that it is not quite stable. For the time being, it is
probably best to stick to Kaffe + Guavac + jdk, or just the jdk
