Using DevTest Workstation with Your Java Environment

You can replace the default JRE used by the DevTest installation with your own Java environment. To do so, it is important to understand how DevTest Workstation selects the JRE to use.

The following priority is used to select what Java VM to use when starting DevTest Workstation:

1. The DevTest Workstation-installed JRE in the LISA_HOME\jre directory
2. LISA_JAVA_HOME environment variable
3. JAVA_HOME environment variable
4. JDK_HOME environment variable

Follow these steps:

1. Rename the LISA_HOME\jre directory (for example, rename jre to jre_default).
2. Point the LISA_JAVA_HOME environment variable to your Java installation directory.
