Java RMI java.security.AccessControlException：访问被拒绝

Question

I'm writing a client-server program with Java RMI and I'm getting an error:

java.security.AccessControlException: access denied ("java.net.SocketPermission" "127.0.0.1:1099" "connect,resolve")

My code looks like this:

package xxx;

import java.rmi.Naming;
import java.rmi.RemoteException;

public class Server extends Engine implements RemoteInterface {

public Server() {
    super();

    if(System.getSecurityManager() == null) {
        System.setSecurityManager(new SecurityManager());
    }

    try {
        Naming.rebind("Test", this);

        System.out.println("Bound in registry!");
    } catch(Exception ex) {
        System.out.println(ex);
    }
}

@Override
public void test() throws RemoteException {
    System.out.println("test() invoked");
}
}

What's wrong?

Answer 1

I had forgot to add the registry and to implement Serializable. Problem solved. I also removed the SecurityManager.

Answer 2

You have installed a SecurityManager but you haven't granted yourself enough permissions to execute this code.

Why do you think you need a SecurityManager at all? Unless you are planning to run uploaded code I would just get rid of it
