I was thinking of creating a
service MBean for monitoring certain parts of the server side of my
application. Is it valid behavior of such an MBean to launch a Swing
interface, say, in its startService() method (supposing it extends
ServiceMBeanSupport)?
To find out, I created a simple
MBean (see below) but unfortunately it makes JBoss hang when I try to shut
down JBoss. I have added and removed the JFrame related code several times,
and the result is always the same: With the JFrame code, JBoss hangs when
shutting down.
Showing the JFrame is no problem –
it pops up just like I wanted it.

public class Server extends
ServiceMBeanSupport implements ServerMBean {
JFrame serverFrame;
public void startService() {
serverFrame = new JFrame("Server");
serverFrame.show();
System.out.println("Server is started");
}
public void stopService() {
serverFrame.hide();
System.out.println("Server is
stopped");
}
}
