Define the JAVA_HOME environment variable

The JAVA_HOME environment variable determines the Java compiler (Javac.exe) that will be used for Plex Java builds. Plex does not automatically set this environment variable which provides you with the flexibility to switch between different versions of the compiler. This setting is not required to run generated applications.

To define the JAVA_HOME environment variable

1. Double-click the System icon in the Windows Control Panel
2. On the Advanced tab, click the Environment Variables button.

• You can define JAVA_HOME either as a user variable or as a system variable.

  Click the appropriate New button, and enter the Variable name as JAVA_HOME and the Variable value as the full path of the folder where the JDK is installed. For JDK 1.7, the full path will be C:\Program Files\Java\jdk1.7.0

• Note that JAVA_HOME should NOT point to the Bin sub-folder of the JDK installation folder. For example:

  

1. Click OK.

You have defined the JAVA_Home environment variable.
