NAME
kaffe - a virtual machine to execute Java(tm) bytecodeSYNOPSIS
- kaffe [options] classname [argument...]
- kaffe [options] -jar filename [argument...]
- The provided options are passed to kaffe virtual machine. Available options are described in the section OPTIONS. The provided arguments are passed to the main function of the called class.
DESCRIPTION
kaffe executes Java(tm) 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.
The specified classname has to be a fully-qualified classname (e.g. foo.bar.ClassName). If kaffe is used with the -jar flag, the class to execute is determined through the manifest file included in the specified Jar-File filename.
kaffe searches for needed classes during program execution on the bootclasspath (see -Xbootclasspath options) and the classpath given by the user (see the -classpath option).

The options for the kaffe command are divided into general options (available on all kaffe installations), options provided for compatibility reasons and further options which are depending on the configuration during compilation of kaffe.
