    No X11 DISPLAY variable

    Hawkeye 11
      Hi ,
      I am trying to start the Admin ACC from dynadmin. But when i click Start ACC in server VM . I am getting following error.

      The ATG Control Center could not be started. Dynamo received the following error message from the JVM: java.awt.HeadlessException: No X11 DISPLAY variable was set, but this program performed an operation which requires it.

      Please help me to fix the issue.

      Thanks ;

          ACC is Java Swing based client UI so it requires a display. Try setting this on the shell where you are starting your server if you are on the same host:

          export DISPLAY=:0.0

          You might want to restart your server after setting this if you want to start ACC in server VM.

          In case you are using PuTTY to tunnel through the UNIX machine then check if "Enable X11 Forwarding" is selected in PuTTY settings. You can find that option under Connection -> SSH -> Tunnels
