Windows – Set JAVA_HOME December 28, 2011

Stage 1. Locate the JRE Installation Directory

If you already know the installation path for the Java Runtime Environment, go to Stage 2 below. Otherwise, find the installation path by following these instructions:

1. If you didn’t change the installation path for the Java Runtime Environment during installation, it will be in a directory under C:\Program Files\Java. Using Explorer, open the directory C:\Program Files\Java.
2. Inside that path will be one or more subdirectories such as C:\Program Files\Java\jre6.

Stage 2. Set the JAVA_HOME Variable

Once you have identified the JRE installation path:

1. Right-click the My Computer icon on your desktop and select Properties.
2. Click the Advanced tab.
3. Click the Environment Variables button.
4. Under System Variables, click New.
5. Enter the variable name as JAVA_HOME.
6. Enter the variable value as the installation path for the Java Development Kit.
   • If your Java installation directory has a space in its path name, you should use the shortened path name (e.g. C:\Progra~1\Java\jre6) in the environment variable instead.
7. Click OK.
8. Click Apply Changes.
9. Restart Windows. (This is not always necessary, but it often prevents problems.)
10. If you are running the Confluence EAR/WAR distribution, rather than the regular Confluence distribution, you may need to restart your application server.
