You can't do that ;)

A JAR file is like a zip file. Some JAR files contain an extra document 
saying which class is the main class, i.e. which one is supposed to be 
run. Those you can run with

kaffe -jar somefile.jar

if that doesn't work, chances are the documentation of the software 
you're trying to run contains a description how to adapt the CLASSPATH 
(java's equivalent of LD_LIBRARY_PATH, if you're familiar with Linux) 
for it to find the classes to run, and what class is the main class.

Just put the class file jperf in your CLASSPATH.
