I got a problem here. basically I have an application which, at startup,
will check for update, it will activate an updater and close itself. The
updater will download jars etc to replace the old jars for the application.
However, the application won't close itself unless the updater closes,
therefore hold the jars as resource and won't allow update.
Anyone have similar issues? How do you guys handle the update problem?

WebStart is how we handle "the update problem". 8-)
Well, I guess if you have to do it yourself, try exec the updater as a whole
new process, and exit the application right after the updater is started.

we have some dll and exe files that used by the JDIC so we can't use
webstart.

That's exactly what I did and the application won't exit :(

webstart can handle native libraries. But never mind...
This seems to work for me:
public class Notepad {
____public static void main (String[] args) throws Exception {
________System.out.println("starting notepad");
________Runtime.getRuntime().exec("notepad.exe");
________System.out.println("notepad started");
____}
}
It exists, leaving the notepad running behind.
