JavaHelp is a compressed output type that works with applications written in the Java programming language. JavaHelp and Java applications run on various platforms.

RoboHelp provides support for the JavaHelp format and automatically creates all Java-based Help features and the HTML-based features such as HTML content and hypertext links. You can also leverage existing WinHelp and HTML projects to create JavaHelp systems. A file compression feature is available for distributing the JavaHelp system.

JavaHelp is a compressed file (JAR file) or a set of files used to run a Help system for a Java application. RoboHelp copies all the files to distribute into the JavaHelp folder, or into a JAR file if you choose to compile Help.

Generating JavaHelp saves the source files in the project subfolder JavaHelp (default).

When you generate JavaHelp files, RoboHelp can translate Related Topics controls into controls specifically for JavaHelp.

1. Place the Bsscjhrc.jar file in the application extensions folder, or in the class path passed to the Java Virtual Machine (Java.exe).

2. Incorporate related topics controls in the topics.

3. Generate the output.

 Add a reference to an external HelpSet file (.hs) when you generate the output.

Adding the reference merges all elements in the external HelpSet file with the existing project.

Supports ActiveX controls, DHTML, JavaScript, startup screens, and Visual Basic scripts.

Style sheets

Support for partial cascading style sheets is provided with JavaHelp 1.1. (External style sheets work correctly.) You can use level 1 cascading style sheets with the Sun Java 2 JDK or later, or Swing 1.1.1 with Sun Java 2 JDK or later.

Table attributes

The following attributes are unsupported:

• Values set in the initial tag (TABLE) of a table override cell width specifications.

• The table width attribute (TABLE WIDTH) functions when specified in absolute pixels, but not in percentages.

• When used within the TABLE tag, the background color attribute (BGCOLOR) does not function.

• When used within the TABLE tag, the break tag (BR) causes the table cell to expand by the number of BR tags used.

  Note: This feature is supported in JavaHelp 1.1.3 and later.

• Table alignment cannot be set precisely.

Unsupported.
