Please look at my work at www.inixsoftware.com. Please send me sample files to look at. You can create the jar file with a simple shell script/batch file or programmatically with the Java Compiler API.
If you mean the files are .java files, it's just a matter of packaging them, which would take only a few seconds per file. I'll teach you how as well as make a .jar package if oyu want.
