was successful or produced an error?

I want to u

Answer 1

I don't know if javaw will write to the %errorlevel% variable, but it might.

echo %errorlevel% after you run it directly to see.

Other than that, you can pipe the output of javaw to a file, then use find to see what the results were. Without knowing the output of it, I can't really help you with that.
