About Java

Confluence needs JDK 1.4 or newer to be installed on your computer.

  • A JRE (Java Runtime Environment) is not enough.
  • JDK 6 is the preferred platform, because it is faster and more reliable.
  • JDK 1.4 or 1.5 are fine for now.
  • Advance notice: Java 1.4 will be deprecated in a future release. Confluence 2.8 will be the last version that supports Java 1.4.
  1. JDK が正しくインストールされているか分からない場合、次を実行して確認してください:
    • Open a command prompt.
      • On Windows: Open your 'Start' menu and select 'Run', then type cmd and click 'OK'.
    • Type the following in the command prompt and then press Enter:
      • Windows: echo %JAVA_HOME%
      • On Unix: echo $JAVA_HOME
    • 結果を確認します:
      • If a line is displayed such as C:\Progra~1\Java\jdk1.5.0_06, please check that the letters just before the final numbers are 'jdk'. If you see those letters, the JDK is installed.
      • If nothing is displayed, or you do not see 'jdk' plus some numbers, the JDK is not installed.
  2. If you have installed a non-Sun JDK, you need to install the Sun JSSE package now.
  3. JDK をインストールする必要がある場合、次の手順に従ってください:
    • Go to the Java Sun download page.
    • Download the version entitled 'JDK 6 Update XX', where 'XX' stands for some number. (Sun will provide the latest version on that page.)
    • ダウンロードが完了したら、Java インストーラーを実行します。途中で、インストール先のディレクトリを選択するように指示されます。後で利用するために、このディレクトリをコピーするか、書き留めてください。
  4. On Windows: Please follow these instructions to set your JAVA_HOME environment variable to the directory you where you have just installed the JDK. By default, this directory is under C:\Program Files\Java.
