javacc is not for compiling java source files, use javac!

JavaCC is a framework if you want to build your own compiler and runtime for a language. Not for your compiling java-files.

Being more specific, you're incorrectly using JavaCC, when what you probably want to use is javac. Give the latter a try and report back? If you don't have javac, you'll need to install an SDK (not just the JRE!)
