You have to first change the permissions on run.sh to make it executable. Try this (from the bin directory): chmod a+x *.sh Then try running it again: ./run.sh By the way, su is the 'switch user' command used to switch to any user. In your case, you asked to switch to the user whose name is "./run.sh" and the system asked you for the password for that user. Not what you intended. To run something as 'root', you could enter: su (enter the password for root) ./run.sh or do the following: sudo ./run/sh (enter your password) Of course, to use sudo you have to first configure it (Ubuntu does this automatically, not sure if OS/X does) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4122764#...
