1 Introduction to Oracle Help

The Oracle Help technologies provide the means for developing and displaying HTML-based help systems for Java applications and for web applications. Authors can create a single help system that can be displayed—without modification—both in a Java environment, using Oracle Help for Java (OHJ); and in a web environment, using Oracle Help for the Web. Alternatively, you can just use Oracle Help for Java if you only need help in a Java environment, or you can just use Oracle Help for the Web if you only need help in a web environment. Oracle Help for the Web is available in two versions: Oracle Help for the Web – Rich Client and Oracle Help for the Web – UIX.

Throughout this guide, Oracle Help is used when the comments apply to both Oracle Help for Java and Oracle Help for the Web. OHJ is used when the comments apply only to Oracle Help for Java. OHW is used when the comments apply only to Oracle Help for the Web.

This chapter includes the following sections:

1.1 Oracle Help for Java

Oracle Help for Java is a set of Java components, a Java API, and a file formats specification for developing and displaying HTML-based help content in a Java environment. OHJ is designed primarily for displaying help for Java applications, although it can also be implemented as a standalone document viewer for use in a Java environment.

The Oracle Help for Java Developer's Kit (OHJDK) includes the OHJ technology plus tools and documentation for developing context-sensitive help for Java applets and applications. This includes the following:

For more information about OHJ features, see Chapter 2, "Oracle Help for Java User Interface".

1.2 Oracle Help for the Web

Oracle Help for the Web, also known as Oracle Help for the Web – Rich Client (OHW-RC) because of its rich interface, delivers HTML-based Help content in a Web environment. It uses the Oracle Application Developer Framework (ADF), which is based on the Java Server Faces (JSF) technology, to build a user interface that follows Oracle's Browser Look And Feel Plus (BLAF+) behaviors and guidelines.

The Oracle Help for the Web can be used in many different situations:

Oracle Help for the Web includes the following:

1.3 Oracle Help in Oracle JDeveloper

Besides being used for the internal JDeveloper help system itself, JDeveloper includes the Oracle Help for Java runtime library, so if you are developing Java applications with JDeveloper, it is easy to include OHJ as the Java help system technology. For more information, see Chapter 12, "Introduction to Oracle Help for Java Developer's Kit".

JDeveloper does not include the Oracle Help for the Web. You can obtain it, and the complete Oracle Help for Java development kit, from the Oracle Technology Network (OTN).

1.4 Oracle Help Licensing and Support

As a service to our customers and the software community, Oracle provides Oracle Help software and support for free. This includes both Oracle Help for Java and Oracle Help for the Web.

Oracle Help is available for free and may be redistributed as the help system for your application. For full information, see the license distributed with the release.
