Did you start it from command-line? If so, try running 'xhost +' as the logged in user first.
[root@dell pwc]# xhost + access control disabled, clients can connect from any host [root@dell pwc]#
What happens if you try to run system-switch-java after running the xhost + command? Same error?
xhost +dell dell being added to access control list Fixed : Close User Error ( I wondered why I was getting this error in other situations too. I wonder why I have gotten this error in past releases. I do notice that my term prompt often show localhost inspite of maxing ip address static and put the address in /etc/hosts and using hostname dell. For some reason, it seems to revert to localhost after reboot. Something for me to work on. Thank You )
No problem, glad the workaround works!
