Vidur,
I used to run orion from my own launcher class for the same reasons. I have
since then removed the cumbersome code. Also orion provides methods for
launching programs/application clients automatically. If possible I suggest
moving down that route instead.
Check out the <client-module> tag in orion-application.xml.
If you still want to use your own launcher class, I have included my old
source, however I haven't used it since version .9 so it may not solve your
problems. Also I never specified the -userThreads flag as you have, but I
was able to spawn new threads outside of orion without a problem. From
reading through the documentation, the userThreads switch is mainly there
for cases where new threads are spawned from within Servlets or EJBs.
I hope you find this at least somewhat useful.

Sorry for reposting this, but it has become absolutely critical and I
would appreciate any help.

Hello,
Could someone please point out what I'm doing wrong. I'm sure I'm
missing something really simple here. I can't get an Orion server
to
run under program control and do some application specific
initialization. I'm inlining some simplified code and output.
Thanks,
Vidur
import javax.naming.*;
import com.evermind.server.*;
public class Server {
public static void main(String[] args) {
try {
ApplicationServer.main(new String[] {"-userThreads"});
Context ctx = new InitialContext();
ctx.lookup ("foo");
}
catch (Exception ex) {
ex.printStackTrace();
System.err.println("Exiting ...");
System.exit (0);
}
}
}
The output is:
Orion/1.1.37 initialized
javax.naming.NamingException: Not in an application scope - start
Orion
with the -userThreads switch if using user-created threads
at com.evermind.server.f9.bh(JAX)
