Answer 1

Thank you for your responses....
i do run the registry on both machines...
as such
"start rmiregistry 1099"
plus i system.out the variable "server" with your suggestion.... it gives out the correct ip of the machines to be looked up!
e.g.
if i want to connect to 192.168.1.2.... the server variable is gives out the correct ip...
i have been trying to solve this problem for a very long time... but can't seem to find a way around it...
this is how i run my server and client
java -Djava.rmi.server.codebase=file:/C:j2sdk1.4.2_04\bin/ -Djava.rmi.server.hostname=localhost
-Djava.security.policy=java.policy MyServer
java -Djava.rmi.server.codebase=file:/C:j2sdk1.4.2_04\bin/ -Djava.security.policy=java.policy MyClient
my policy file is: just wanted to be very relaxed
grant {
permission java.net.SocketPermission "*:*","connect,accept,resolve";
permission java.net.SocketPermission.AllPermission;
permission java.security.AllPermission;
permission java.io.FilePermission "c:\\j2sdk1.4.2_04/bin\\-","read,write,delete";
