Just to let people know that there has been some exciting progress in the GNU java toolchain as of late. At this point gcj/gij can compile .java and .class files to native code, intrerpret .class files dynamically, and many other items. It is to the point where Fedora Core 4 will ship with it installed and enabled by default as well as eclipse running nativly compiled for the platform.
The biggest failure of this toolchain is the fact that the GUI parts are incomplete. This is not a problem though for those who use SWT or bypass AWT and use OpenGL or other native libraries directly. For many of you this could be a replacement for jet and allow you to distribute native executables to populat platforms and still retain compatibility by supporting interpreted/jit compilation as well.
For those interested ... here is a flash demo of using eclipse and glade to develop native gnome applications. ( http://people.redhat.com/overholt/nativeeclipse/index.html
