When deploying Confluence using .exe installer, it will come with a bundled JRE (JAVA). Sometimes, in order to upgrade the JAVA version, Confluence needs to switch from bundled JRE to user installed JAVA.

Step-by-step guide

  1. Install JAVA in your machine (see Installing Java for Confluence)
  2. Stop Confluence

  3. Identify the name of the service that Confluence is installed as in Windows (Go to Control Panel > Administrative Tools > Services):

    (info) In the above example, the service name is Confluence121213135538
  4. Open the command window (Choose Start > cmd.exe
  5. cd to the bin directory of your Confluence instance (or the bin directory of your Tomcat installation if you are running Confluence EAR/WAR).
  6. Run the following command for Confluence 5.8:

     

    tomcat8w  //ES//<SERVICENAME>

     

    (info) In the above example, it would be tomcat8w //ES//Confluence121213135538
    The Tomcat version number may be different if you are using an earlier version of Confluence. 

  7. Click on the Java tab to see the list of current start-up options:
  8. Uncheck the 'Use default'
  9. Modify the 'Java Virtual Machine' to point at the jvm.dll of the installed JAVA in Step 1
    (e.g. Java Virtual Machine: C:\Program Files (x86)\Java\jdk1.8.0_66\jre\bin\server\jvm.dll or C:\Program Files (x86)\Java\jre1.8.0_66\bin\client\jvm.dll)
  10. Click 'OK'
  11. Start Confluence
