After you have installed the Java Development Kit in Windows, you must set the JAVA_HOME variable to the installation directory.

Please check that you have a JDK or SDK --- Java JRE is not enough

A common problem is that people have only installed the Java Runtime Environment (JRE). You need either a Java Development Kit (JDK) or J2SE Software Development Kit (SDK). To confirm that you have the right version, you can check the Java installation path. Unless you changed the path during installation, Java will be installed to a subdirectory under C:\Program Files\Java, for example C:\Program Files\Java\jdk1.5.0_02

Open C:\Program Files\Java and confirm the installation path is for a JDK or SDK. JRE installations are not suitable, and have an installation directory begining with jre. The numbers after the jre are not relevant. Example JREs are:
(error) jre1.4.0_02
(error) jre1.5.0_14

SDK and JDK installations are suitable. Their installation directory begins with jdk or j2sdk, the numbers at the end are not relevant. Example JDK and SDKs are:
(tick) jdk1.5.0_02
(tick) j2sdk1.5.0_09

Any installation directory starting with jdk or j2sdk is valid. If you cannot see an installed JDK or SDK, install the JDK now from the JDK download site

Stage 1. Locate the JDK Installation Directory

If you already know the installation path for the Java or Software Development Kit, go to Stage 2 below. Otherwise, find the installation path by following these instructions:

  1. Unless you changed the installation path for the Java Development Kit 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 jdk1.5.0_08. If you have just installed the Java Development Kit, it will be installed to the newest directory, which you can find by sorting by date. For example, it may be installed in C:\Program Files\Java\jdk1.5.0_08. This is the installation path.

手順 2. JAVA_HOME 変数を設定する

Once you have identified the JDK 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. 変数値に Java Development Kit (JDK) のインストール パスを入力します。
  7. Click 'OK'.
  8. Click 'Apply Changes'.
  9. If you are running Confluence as a EAR/WAR rather than the Standalone, you may need to restart your application server.

This diagram shows setting the JAVA_HOME variable to an installation path of c:/j2sdk1.4.2:

If you came here from Installing Confluence Standalone Using the Automatic Installer, go back and begin Stage 3.
