Omni Systems, Inc. Mif2Go User's Guide, Version 55
> 11 Generating JavaHelp or Oracle Help > 11.3 Setting up a JavaHelp or Oracle Help project > 11.3.5 Establishing a JavaHelp environment
To use JavaHelp, you must have both JavaHelp
and the Java Runtime Environment (JRE) installed on your system, and
you must set some environment variables. If you plan to create .jar
files, you will also need jar.exe
from the
Java Software Development Kit (JDK).
JavaHelp 2.0 requires Java Standard Edition (Java SE). Both Java SE and JavaHelp are available for download; see §11.2 Obtaining tools for a Java-based Help system.
You must create Windows environment variables
JAVA_HOME
and JHHOME
,
if they are not already defined on your system; for example, on Windows
2000 or Windows XP:
Control Panel > System > Advanced > Environment Variables
These environment variables are defined as follows:
JAVA_HOME path\to\JavaSE\executables
JHHOME path\to\JavaHelp\executables
JAVA_HOME=C:\Java\j2re1.4.2_03\bin
JHHOME=C:\JH\jh20\javahelp\bin
To check the results after Mif2Go generates JavaHelp files, you can use the JavaHelp
viewer included in the JavaHelp installation: hsviewer.jar
,
located in the demos\bin
directory. The JavaHelp System User’s Guide
shows how to set up a shortcut to the viewer.
