The other thing you should bear in mind is that "jar" is a tool like "ar", "tar" or "zip" - it constructs, inspects or unpacks ".jar" files. To _run_ a java program you want the "java" command. Usually a Java app is distributed as a jar file, an archive containing the program, and the command "java -jar foo.jar" is used to run it. You still need "java" in your $PATH, or to invoke "java" explicitly (eg "/usr/java/bin/java") if it is not in your $PATH. Usually it is desirable to adjust your $PATH you include this stuff, saving painful long paths later. Both "java" and "jar" have manual pages, quite good ones. If java in installed out of the "vendor" area (here "vendor" means redhat/fedora and "/usr/bin" is part of their area - that they expect a free hand in), you will need to adjust your $MANPATH to include the "..../man" directory of wherever the java package is installed, much as you have to adjust $PATH to include the "..../bin" directory to run "java" without using the full path of the command.
