This page contains instructions for installing a Java Development Kit (JDK) for Windows and Linux.

Please refer to our Supported Platforms topic for details of the Java versions that are supported for Confluence.
Note: a JRE (Java Runtime Environment) is not enough to run Confluence.

Mac OS X users can ignore these instructions because this operating system comes pre-installed with a JDK.

OpenJDK is currently not supported. A JIRA issue to request support for this JDK has been created.

JDK のインストール

A JDK needs to be installed on the same server machine that will have Confluence installed.

Windows で JDK をインストールする

  1. If you are not sure whether you have a JDK installed correctly, please confirm by doing the following:
    • Run a complete directory search (using the 'All File and Folders' option if available) on your drives for the occurrence of 'jdk' in the filename.
      • If your results retrieve a folder with the name 'jdk' immediately followed by a series of version numbers (for example, jdk1.6.0_17), then the JDK has been installed. You should double-check the contents of this folder to ensure that the installation files are intact. If you are unsure about this, proceed to step 2 to re-install the JDK. Otherwise, proceed to step 3 to check that your JAVA_HOME environment variable has been set correctly.
      • If you do not retrieve a result like this, then it is highly likely that the JDK has not been installed.
  2. JDK をインストールするには、次の手順に従ってください:
    • Go to the Java download page.
    • Download the version entitled 'JDK 6 Update XX', where 'XX' stands for some number. (The latest version will be available 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。
  3. Check that the JAVA_HOME environment variable has been set correctly.
    • Open the Start menu, choose Run, type cmd in the Run dialog box and click OK.
    • In the command prompt window, type echo %JAVA_HOME% and then press Enter.
    • 結果を確認します:
      • If a directory path is displayed that looks similar to one of the following examples, with the letters 'jdk' immediately preceding a series of version numbers, and this path matches the location where you installed the JDK in step 2, then your JDK has been successfully installed and your JAVA_HOME environment variable has been set correctly.
        Examples of typical JAVA_HOME environment variable values:
        • C:\Program Files\Java\jdk1.6.0_17
        • C:\Progra~1\Java\jdk1.6.0_17
        • C:\Java\jdk1.6.0_17
        • C:\jdk1.6.0_17
      • If nothing is displayed or you do not see 'jdk' immediately followed by a series of version numbers (like one of the examples above), then you need to set the JAVA_HOME environment variable. 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.

Linux で JDK をインストールする

  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:
    1. シェル コンソールを開く。
    2. Type echo $JAVA_HOME in the shell console and then press Enter
    3. 結果を確認します:
      • If a line is displayed such as /opt/jdk1.6.0_12 or /usr/lib/jvm/java-6-sun, then your JDK is installed and properly configured.
      • If nothing is displayed, then you either need to install the JDK or set the $JAVA_HOME environment variable. You can set this environment variable in your user account's 'profile' file. Alternatively, you can set this after installing Confluence (in step 4 below) by defining this path in your Confluence installation's setenv.sh file, usually located in the Confluence bin directory.
      • If you have installed an unsupported JDK and you want to use SSL then you need to install the Sun JSSE package.
  2. 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 download page.
    • Download the version entitled 'JDK 6 Update XX', where 'XX' stands for some number. (The latest version is available on that page.)
    • When the download has finished, run the Java installer. Detailed installation instructions are provided on Oracle's website.
