Hello Andrew,
org.objectweb.jonas.adm.Adm is a java.rmi.server.UnicastRemoteObject
and implements org.objectweb.jonas.adm.AdmInterface which extends
java.rmi.Remote.
So, you can access to the org.objectweb.jonas.adm.Adm object
by the way of the org.objectweb.jonas.adm.AdmInterface interface
and the Naming Directory.
You can see an example in the org.objectweb.jonas.adm.AdmServer
source code.
It's look like:
--------------------------------------------------
// Gets reference on Adm object
AdmInterface admI = null;
{
String admName = Env.getJonasName() + "_Adm";
try {
admI = (AdmInterface) initialContext.lookup(admName);
} catch (Exception e) {
Trace.errln ("Server.initialContext.lookup("+admName+") : " + e);
e.printStackTrace();
return;
}
}
.................
.................
////// Stops Server
if(sOption){
try{
admI.stopServer();
}catch (RemoteException ex) {
System.exit(0);
}
}
---------------------------------------------------
Best regards.
H�l�ne.
