Well, I did not have RMISecurityManager, so I added it but it did not
changed anything. Also, I've found one small RMI example and it didn't had
RMISecurityManager too, but it is working fine on my PC. So, my question is:
in which cases I need RMISecurityManager? This is how I installes securitiy
manager according to the Sun's RMI tutorial:

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

The only static method or variable in my project is main() method in my app.

I've added entry to the java.policy file as stated in Sun's RMI tutorial but
it didn't changed anything:
grant {
    permission java.net.SocketPermission "*:1024-65535",
        "connect,accept";
    permission java.net.SocketPermission "*:80", "connect";
};Here is source code of my class, I've removed everything irrelevant for
RMI and same exception still occurs:package dory2;import
java.security.*;import java.security.cert.*;import java.rmi.*;import
java.rmi.server.*;public class DoryMain {  private boolean doExecute = true;
//This method below should be called as remote procedure  public void

return;  }  public DoryMain() {    if (System.getSecurityManager() == null)
{      System.setSecurityManager(new RMISecurityManager());    }    String
name = "rmi://localhost:1099/StopDory";    try {        StopDoryIntf rmi =
new StopDoryEngine(this);        Naming.rebind(name, rmi);
System.out.println("StopDoryEngine bound");    } catch (Exception e)
{        System.err.println("StopDoryEngine exception: " +
e.getMessage());        e.printStackTrace();    }    while (doExecute) {
