[SOLVED] Error Message when using Eclipse for small graphics

[chr]

hello,

i'm on an academic course learning java. the lecturer said we should use eclipse for the programming.

when i started to program small apps, which were just runing on the console, everything was ok.

bus as soon as i start to work with graphical apllications i get an error mesage when i want to run it:
