To generate Sun JavaHelp 2.0, you must have the Java2 Platform SDK version 1.2.2 or later installed on your computer. You can download the Java2 Platform SDK for free from the Sun Microsystems Web site at http://java.sun.com/javase/index.jsp.

To view Sun JavaHelp, users must have the Java Runtime Environment (JRE) installed on their computer. Typically, application developers configure their applications to install the JRE with the Sun JavaHelp content to ensure users can view the Sun JavaHelp while using the application. Sun JavaHelp components must be installed and viewed on the local computer.
