About the Oracle Help for Java Developer's Kit

The Oracle Help for Java Developer's Kit (OHJDK) is a set of Java components and an API for developing and displaying HTML-based help content in a Java environment. It includes the Oracle Help for Java (OHJ) engine and additional tools necessary for implementing context-sensitive help in Java applets and applications.

The Oracle Help for Java engine is a full-featured Java-based help system for Java applications and applets. It provides pure Java components for navigating and displaying context-sensitive help. Oracle Help for Java is available for free, and may be redistributed as the help system for your application (see the license distributed with the release).

Oracle Help for Java supports help content in several file formats, including extensions of the Sun Microsystem's JavaHelp and Microsoft HTMLHelp standards. If you are authoring help content without using a help authoring tool, it will be helpful to read About the Files. If you are using a third party help authoring system that supports OHJ, refer to the documentation provided.
