But when try install - receive this error:

This program requires DISPLAY environment variable to be set.
Please re-run after assigning an appropriate value to DISPLAY.

But this is server - I cannot install graphic system. What can i do? Thanks.

Answer 1

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.

Answer 2

You can either:

1. 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

2. Unzip installation manually

Answer 3

edit bash profile

vi ~/.bash_profile

set variable

export DISPLAY=<VALUE>

save and close and to test

echo $DISPLAY
