Windows での JAVA_HOME 変数の設定

Stage 1. Locate the JDK Installation Directory

If you already know the installation path for the Java 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 jdk1.6.0_17. 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\jdk1.6.0_17. 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。
   • 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\jdk1.6.0_24) 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 Confluence distribution, you may need to restart your application server.
