Starting Swing GUI without extra console window?

Hello,

Perhaps this is a stupid question.
If you use the usual way to start a Swing GUI

public static void main(String[] args) {
invokeLater(new Runnable() {
public void run() { // etc.
}
});
}

then (at least in Windows), if you start this with a .bat file, you
still see an extra console window. If you close that window, then the
Swing GUI goes away, too. How can i start 'just the Swing GUI'?

And use the dos START /B command in the bat file if necessary, you need to
on Win2000, as even with javaw the console window remains.

Isn't that only when you actually use "start javaw SomeClass" ?

I'd expect not to see a console window on Win2000, when you start an
application with "javaw SomeClass". That's the behaviour I'm used to on my
Win2000 machines.

It's not javaw that opens/maintains the console window VisionSet
mentions, but the cmd.exe interpreter. If a shortcut, rather than a
batch file, is used to launch javaw TheClass, then as you suggest, the
console window won't show up at all.

Many thanks to all respondents!
start /b javaw TheClass
That did the trick. And using a shortcut works even nicer.

Use webstart! Is an xml file with extension .jnlp. Then double click on
the file and the application starts. In the same way you can insert a
link to the jnlp file on an html page.
