Re: RMI Problem

[Michael hawes <mihawes@xxxxxxxxx>]

Hi,

Does the server program register itself with the RMI
registry? Does the client program request this
registered class?

An example might be. On the server AddServerImpl
class, main method:

try {
        
System.setSecurityManager(new RMISecurityManager() );
                
AddServerImpl server = new AddServerImpl();

Naming.rebind("//Myserver":1099" + "/myserver",
server);

}

On the client side:

theServer =
(AddServerIntf)Naming.lookup("rmi://Myserver:1099" +
"/myserver");

where Myserver is the name of your server system and
1099 is the port number (1099 happend to be the
default).

When you start the RMI registry, the registry program
must be able to find the server class in it's
classpath. It took me a while to figure that one out.
