Mental Java error

JCreator keeps giving me the error below.

My lecturer has no clue how to fix it. Any ideas?

I'm not well up on Java, but it looks like the default output of java.exe when it's called with no arguments (or the help switch). There's probably an option in the IDE where you set the path and arguments to java.exe ... maybe they're not asking for java.exe, but javac.exe and you've got it pointed at the wrong file. Do you have the SDK installed or just the runtime?

I just ran java in command prompt there with no arguments and got the exact same "error". Looks like your ide is not set up correctly.

Have you tried using another IDE like eclipse?

Have you tried compiling manually with the "javac" command on the command line? Forget using IDE's when problems like this occur, as the problem could be the IDE itself and any associated environmental variables.
