Yes there was an instance running and once i killed it I was able to then complete the "java -jar" installation and close the terminal without any problem. But then what? Sorry for being so obtuse Erel, but I do not see any way to begin using the program. Should there be an icon or is there another command I need to use?

As the attached screenshot shows "B4i Build Server is running", but how do I bring up the IDE?
