Debugging output (Newbie question)

I am testing a few of the tutorial java programs in JME 1.0. I've renamed one of them and put some

debugging output with System.out.println. It compiles and runs okay but i don't see the

output from println. Since i've renamed the java program, I couldn't pick up the old version,

so I'm puzzled as to why I am not seeing the output from println. :?
