Philippe,
The problem Murad is working on is that we take Jonas, we embed it with
Jetty and several other processes which runs in separate threads inside of
the same JVM as a part of our very lightweight J2EE like server
When we want to stop this server we want to stop all these processes so they
can clean up and end gracefully and then when everything is done, shutdown
the JVM so in this case we are responsible for System.exit(0) and not Jonas.
Do you think the best solution for this would be to change stopServer() to
do not call System.exit(0) and add new method
public void killServer() throws RemoteException {
stopServer()
System.exit(0);
}
Thanks,
Miro Halas

Hi,
the semantic of JonasAdmin -s is
stops all the JOnAS services running and
kill the server.
I am not sure to understand when it is interesting to stops
all services without killing server, and it your case who will
be take the decision to do the System.exit(0);
By the way, may be we can provide a new command in JOnASAdmin
JonasAdmin -k = stops services+kill server
JonasAdmin -s = stops services without killing server
I wonder to know what the jonas users think of this.
For the moment a solution for you, may be to modify your version
of JOnASAdmin by removing System.exit(0) in
objectweb/jonas/src/org/objectweb/jonas/adm/adm.java and rebuilt it
by making make in this directory.
regards,
