Try this, before executing:

export DISPLAY=:0

If you're connecting through Putty to a headless system, don't forget to have X11 client on your local machine.

You can either:

Generate an answer file on any machine wich has GUI (run setup in dry run mode)

./java_ee_sdk-6u2-unix-ml.sh -n template

and then use that template on server machine with silent mode option

./java_ee_sdk-6u2-unix-ml.sh -a template -s
Unzip installation manually

What value does display usually contain? Can you provide an example of what you have on your system?

jstarek Over a year ago

Just assigning some value to $DISPLAY is not helpful -- the J2EE installer tries to connect to an X server, and if there is none, it will not work. The error message usually is "Entering setup... java.lang.InternalError: Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable."
