Trouble running RMI (newbie)

[john]

Hi:

I know this is a Corba group, but I am hopeful that people
with Corba experience will have some RMI experience.
(at least some of the people) If you can help, I would appreciate
it.

I am having trouble starting my rmi application. It is a simple
program designed by our prof to help us learn how to use RMI.
I am getting no where with it. Everything is fine until I start
the client. At least I think everything is fine. I did use
stack trace on the exception to get feed back. I sense what it
is telling me that that paths I am using are not correct.
The exhbibits below give the steps I follow. The second exhibit
is the stack trace. The third is the client and server code. I left
out all the other stuff since it would just add bulk to this already
long request for help.

Thanks
John

----------- exhibit 1---------------------------
the steps I use for setting up and running the rmi application

S:\A2_498_rmi1A2_498_rmi1\RMI_DEMO_1>javac *.java

C:\A2_498_rmi1>rmic RMI_DEMO_1.Worker -d .

C:\A2_498_rmi1>start rmiregistry

C:\A2_498_rmi1>java -Djava.secturity.policy=total.policy RMI_DEMO_1.Server

C:\A2_498_rmi1>java -Djava.security.policy=total.policy RMI_DEMO_1.Client
localhost/w1 7

The stack trace

3a) the code in the client
...
public static void main(String[] args) {
try {
String name = args[0];
WorkerInterface w = (WorkerInterface)Naming.lookup(name);
int number = Integer.parseInt(args[1]);
Foo foo = new Foo();
System.out.println(w.call(foo, number));
} catch(Exception e) {e.printStackTrace(System.out);}
}
...
3b) the code in the server
...
public static void main(String[] args) {

System.setSecurityManager(new RMISecurityManager());

String name = "localhost/";

try {
Worker w1 = new Worker();
Naming.rebind(name + "w1", w1);
} catch(Exception e) {}

Hi John,

from the stacktrace it seems that your server isn't registered in
RMIRegistry under name you are looking for him therefore "NotBoundException"

try to use in server:
Naming.rebind("//localhost:1099/w1",w1);

Then client should bind to name "w1"

I hope it helps.
