Free Help-System for commercial Java-Application?

Question

I'm searching for a Help-System for my Java-Application. Since it may go commercial someday, I need a System that allows that, but doesn't cost anything at the moment.

I know there is always that question "What? You want to earn money with that but don't want to pay for licenses??". At the moment i'm a student without any money, so i just can't pay anything and search for available free solutions.

Until now, i found two of them:

JavaHelp - HTML Help System

PDFhelp - PDF based alternative for JavaHelp

The Problem is: JavaHelp is under GPL 2. Since i don't want to open my source, i don't want to use that. PDFhelp seems to need JPedal, a commercial PDF Library that costs a lot.

So is there a free solution which i can use for my Project? Until now, i didn't find any other. The only way was to build my own Help-System.

Answer 1

JavaHelp is under GPL 2. But it includes the ClassPathException, which means that i'm free to use it without opening my soure, as long as i only include the library/jar-file and don't modify it.
