Providing Help Contents with Java Program

What is the best pract开发者_StackOverflow中文版ice for providing "Help Contents" in a Java Application. Should I use ".CHM" files, do Linux operating systems have built-in support for ".CHM" files? I was thinking of how I was going to host my project and I was looking into Google Code Projects and that seems perfect for my needs, so should I just redirect them to the support section of my Google Code Project?

Web based help is preferable in my mind, as you can modify/update it after the application is released. If the help is bundled with the application, you would need to re-release the application if you want to change the help.

Personally, I would go for a JEditorPane displaying HTML or rich text (RTF) content. The application could find help updates by fetching new content from a URL, or displaying a cached version of the content in case of failure. In any case, your help files are clean and easily maintainable, and compliant with Java's component (OS independent).
