"RapidMinerGUI java error"
Contributor I
Hello,
I have just installed the Community Edition of RM Server on Ubuntu 14.04. I am getting the below error when trying to run RM from the cmd line. When I double click the RapidMinerGUI icon, nothing happens. Help is appreciated. Thanks.

Answers
judging by the log extract you did not install RapidMiner Server but rather RapidMiner Studio. Furthermore the log extract says you're trying to start the GUI of Studio on a headless server which cannot display GUI. So either please download the actual RapidMiner Server and use that or use the /scripts/rapidminer start script instead of the RapidMinerGUI script.
