Mac users can ignore these instructions, because OS X comes with a Java Development Kit.

Confluence requires Java 5 (JDK 1.5) or later

Confluence needs JDK 1.5 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 1.5 is fine.
  • JDK 1.4 is not supported in Confluence 2.9 or later.
  1. If you are not sure whether you have JDK installed correctly, please confirm by doing the following:
    • 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:
      • On Windows: echo %JAVA_HOME%
      • On Unix: echo $JAVA_HOME
    • View the result:
      • 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. If you need to install the 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.
  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.
