Question

I am trying to run a test app in griffon. I can create the app, but when I go to run it I get the following error(s):

Solution 2

Found it!!! I needed to have the JRE installed and I didn't. It was looking for a dependency that I needed.

OTHER TIPS

As mentionioned in the docs at http://docs.oracle.com/javase/6/docs/api/java/awt/HeadlessException.html , this should be a problem with keyboard, mouse or display.

Assuming you did not force "-Djava.awt.headless=true", this is most likely caused by a missing connection to a X-server.

Type

echo $DISPLAY

in a terminal window. Usually this outputs ":0". Make sure that variable is set (happens automatically for terminal windows), and try starting a very basic X application, such as "xterm". If that works, the griffon app should launch and display.
