Setting the JAVA_HOME Variable in Windows

After you've installed Java in Windows, you must set the  JAVA_HOME  environment variable to point to the Java installation directory.

This information is only relevant if you're installing Confluence manually on a Windows server. If you're using the installer we'll do this part for you.

If you installed the Java Development Kit (JDK) you'll be setting the JAVA_HOME environment variable. If you installed the Java Runtime Environment (JRE) you will follow the same steps but set the JRE_HOME environment variable instead. 

Set the JAVA_HOME Variable

To set the JAVA_HOME variable:

  1. Find out where Java is installed. If you didn't change the path during installation, it will be something like this:
    C:\Program Files\Java\jdk1.8.0_65
  2. In Windows 7 right click My Computer and select Properties > Advanced.
    In Windows 8 go to Control Panel > System > Advanced System Settings.
  3. Click the Environment Variables button.
  4. Under System Variables, click New.
  5. In the Variable Name field, enter:
    • JAVA_HOME if you installed the JDK (Java Development Kit)
    • JRE_HOME if you installed the JRE (Java Runtime Environment) 
  6. In the Variable Value field, enter your JDK or JRE installation path.

    If the path contains spaces, use the shortened path name, for example C:\Progra~1\Java\jdk1.8.0_65)


    Note for Windows users on 64-bit systems

    Progra~1 = 'Program Files'
    Progra~2 = 'Program Files(x86)'

  7. Click OK and Apply Changes as prompted.

You'll need to close any re-open any command windows that were open before you made these changes as there's no way to reload environment variables from an active command prompt. If the changes don't take effect even after reopening the command window, restart Windows.
