I have a script which runs a Java GUI application using "java -jar app.jar". I have added the script to the crontab to run every minute, check the processlist if the application is up. If it isn't it should start the application.
However, it only starts the process, but not the GUI. I have added "export DISPLAY=:0" to the top of the script, but that didn't help.
How do I make cron run the program as if I am starting it myself?
Thanks

This page explains how to run a GUI app using cron:
To run GUI application using cron in the command section replace the command name part the following way
env DISPLAY=:0 gui_appnameThe
env DISPLAY=:0portion will tell cron to use the current display (desktop) for the program "gui_appname".For example to run the rtorrent client(A terminal based popular torrent client in Linux) the crontab looks like this
# m h dom mon dow command 47 09 18 11 * env DISPLAY=:0 gnome-terminal -e rtorrent

1I have found that example, but couldn't figure out what the gui_appname is for an application run via "java -jar app.jar". – nanoman – 2012-04-23T12:41:06.257
