I am having a problem opening any port other than 1099 for the RMI registry. I have checked that nothing else is using that port so what else could it be?

I am new to RMI so it is probably something I have done wrong, here is a snipit of my code

public FooServer implements MyServer

The app crashes on the first line. I have not used a RMI Security Manager which I have read about, will this affect which ports I can use?

Matt I am also new to RMI but I have recently finished an assignment on it. I will try my best to answer your problem.

Try making your own policy file. I have pasted my policy file just use this and see if it makes any difference

IF you look closely u can see a line
java.net.SocketPermission "*:1024-65535", "listen,accept,connect";

this will give your program permission to open any port for you. I guess I am not sure.

grant {

// allows anyone to listen on un-privileged ports
permission java.security.AllPermission;
permission java.net.SocketPermission "*:1024-65535", "listen,accept,connect";
permission java.io.FilePermission "d:\Remote\Server\classes\-", "read";
