"Daemonizing" a Java program

Is it possible to detach a Java program from its terminal, eg the MSDOS prompt for Win95, or the xterm for Lynix??? I have been banging my head against the wall for quite a while on this. Some process similar to giving a thread daemon status on Unix-based machines. Instantiating a new class inside a thread with setDaemon(true) and then exiting does not work! Any other ideas/options.

Thx,

Use javaw instead of java to run the program.

say you have a test daemon Test.class

run it using


javaw Test

If you want a daemon to start when the user logs in

in nt, you put command javaw classname in the startup panel.
in unix, add this in initialization file.

you can close the input and output streams,

System.in.close();

System.out.close();
System.err.close();

This detaches java program from terminal.

Thx so much, I had never noticed that or used that program in 1-1/2 years of Java programming. Time to look over the docs again I guess.

Thanx for waking me up!
