Hide BAT file window when invoking it from Java

Question

I'm invoking the execution of a BAT file from Java with the Runtime object.

Is it possible to hide the BAT window during the execution of the script? How is it possible?

Answer 1

Try using javaw rather than java to run the script.

Update: Sorry, I think I read the question wrong. I know I've suppressed a .bat window doing something along these lines before:

Answer 2

Invoke start as the first command in your process builder, with the /b option:

ProcessBuilder builder = new ProcessBuilder("start", "/b", "<mybatchcommand>");
// .. set environment, handle streams
builder.start();

The /b options suppresses the command window.
