javaw

[jignesh soni]

whats "javaw.exe" for ?
Does it get installed automatically with jre ? What is it used for ?

[Ernest Friedman-Hill]

It's the same as java.exe, but it doesn't open stdin/stdout to a console. It's useful for running GUI apps. It's the preferred program for running clickable JAR files.

I'd like to think the "w" stands for "windowed", because as Ernest said it should be used for GUI apps - application with a window.

Hmm... I'm sorry, but in this case, what's the difference between java -jar and javaw?

java -jar will open a DOS window. javaw won't.

So if I want to run a byte code using javaw , I can use "javaw bytecode" instead of "java bytecode" , right ?

In what situation shall I opt to use javaw and what is the advantage of using javaw over java ?

I've explained it twice now. I think the only way you'll understand is to try it yourself. Set up your machine to run jars by double-clicking to use java.exe, then change it to use javaw.exe. You should see the obvious difference: with java.exe, a console window appears, but with javaw.exe, it does not.

Ernest,

Thanks for your answer
