kaffe - a virtual machine to execute Java(tm) bytecode
kaffe [-help] [-version] [-O] [-classpath path] [-ss size] [-verify] [-verify-remote] [-noverify] [-Dproperty] classname
kaffe executes classfile containing Java bytecode, either as a pure bytecode interpreter, or by doing "just-in-time" code conversion from the abstract code to the host machine’s native code.
-help |
Give a short usage message. |
-version
Print the version number.
-O |
Enable code optimisations. These are currently under development. |
-ss size
Set the maximum stack size to size
-classpath path
Set the path which is searched for compiled classes, e.g. /usr/local/share/kaffe
-verify
Verify all bytecode. Not implemented yet.
-verifyremote
Verify bytecode obtained via the network. Not implemented yet.
-noverify
Do not verify any bytecode.
-Dproperty=value
Set a property to a given value.
classname
Java class name to invoke. Note that this is not the filename.
CLASSPATH
A colon-separated list of directories in which to search for .class files.
KAFFEHOME
Not documented yet.
LD_LIBRARY_PATH
A colon-separated list of directories in which to search for libraries. See ld.so(1) for details. This needs to be set if Kaffe’s shared libraries are installed in a location not part of the dynamic loader’s default search path.

Kaffe forms part of the Jolt project. This projects aims to develop the necessary components for a completely free version of the Java system. This includes the Kaffe virtual machine, the Guavac compiler, and the Kream class library. Information on this projects and its components can be found on the mailing list jolt-list@redhat.com or on the web pages http://www.redhat.com/jolt/.
Support for graphical code is still under development.
The just-in-time code conversion is not supported on all of the architectures.
Optimisation is still under construction.
Code verification is not implemented yet.
Kaffe is still undergoing rapid development. Check the NOTES/BUGS file in the source distributions for known bugs not mentioned here.
Kaffe was originally written by Tim Wilkinson <tim@tjwassoc.demon.co.uk>, 1996. Many others contributed to the Kaffe project. They are listed in the source distribution’s NOTES/THANKS and NOTES/HELPERS files.
Kaffe is distributed under a Berkeley style license. For full details, see the file license.terms in the source distribution for full details.
Essentially you can use Kaffe for both personal and commerical purpose, on its own or as part of another package.
