This page contains instructions for installing the Sun Java Development Kit (JDK) for Windows and Linux/UNIX.

Please refer to our Supported Platforms topic for details on the Sun JDK versions which are supported for Confluence.

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

Installing the Sun JDK on Windows

  1. If you are not sure whether you have Sun's 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, jdk1.5.0_06), then your Sun 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 Sun 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 your Sun JDK has not been installed.
  2. To install the Sun JDK, follow these instructions:
    • 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.)
    • When the download has finished, run the Java installer. At one point, you will be asked to choose a directory to install to. Copy or write this directory down for use later.
  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 the 'OK' button.
    • In the command prompt window, type echo %JAVA_HOME% and then press Enter.
    • View the result:
      • If a directory path is display 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 Sun JDK in step 2, then your Sun 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.
