Setting up JAVA_HOME on Window

The JAVA_HOME variable should point to the JDK’s bin folder in order for Java applications (jar, war, etc) to know where Java lives.

To setup a JAVA_HOME environment variable on Windows.

  • Right click on the My Computer icon in the start menu or on the desktop and select properties
  • Click the Advanced Tab
  • Click the Environment Variables button
  • Under System Variable, click New
  • Enter the variable name as JAVA_HOME
  • Enter the variable value as the install path for the Development Kit
  • Click OK
  • Click Apply Changes

Word of caution, Java is not fond of spaces, so I use pathnames without spaces.

Note: You will need to click OK, apply changes AND reload cmd to see the changes there.
