Security.policy issue when running javarmi server.

Question

hi guys,
i am trying to run a sample javarmi applications.
the code as follows:
file name : myRMIInterface.java
//package my_rmi_classes;
public interface myRMIInterface extends java.rmi.Remote {
public java.util.Date getDate() throws java.rmi.RemoteException;
//implementation program
// package my_rmi_classes;
import java.rmi.*;
import java.rmi.server.UnicastRemoteObject;
public class myRMIImpl extends UnicastRemoteObject implements myRMIInterface
public myRMIImpl(String name) throws RemoteException
     super();
     try
          Naming.rebind(name,this);
     catch(Exception e)
          System.out.println("Exception occured:"+e);
public java.util.Date getDate()
     return new java.util.Date();
application : myRMIServer.java
//package my_rmi_classes;
import java.rmi.*;
import java.rmi.server.UnicastRemoteObject;
public class myRMIServer {
* @param args the command line arguments
public static void main(String[] argv)
// TODO code application logic here
System.setSecurityManager(new RMISecurityManager());
try
     myRMIImpl implementation = new myRMIImpl("myRMIimplInstance");
catch(Exception e)
     System.out.println("satish exception occured :" +e);
steps which i follow to run this applicatons:
step 1: complie all the applications.
step 2: create myRMIImpl_Stub.class file by running RMIC
step 3: start rmiregistry
step 4: i download a policy file from sun website and i place that file in my source code folder.
i use 3 types of policy files which are as follows,,,
type 1:
grant{
permission java.net.SocketPermission "localhost:1099", "connect, resolve";
permission java.net.SocketPermission "localhost:1024-", "connect, resolve";
permission java.net.SocketPermission "localhost:1024-", "accept, resolve";
type 2:
grant codeBase "C:/week_project/rmi server files/" {
permission java.security.AllPermission;
note: all my java files(source code) files are in the folder (rmi server files). i copy all policy files in the same folder.
type 3:
grant {
     // Allow everything for now
     permission java.security.AllPermission;
step 5:
a:) C:\week_project\rmi server files\java -Djava.security.policy=(policy name).policy myRMIServer
b:) C:\week_project\rmi server files\java -Djava.security.policy=C:\........\(policy name).policy myRMIServer
when i work with type-1 policy file i got error message as follows
ERROR:
Exception occured:java.security.AccessControlException: access denied (java.net.SocketPermission 127.0.0.1:1099 connect,resolve)
type -2 policy file
ERROR
java.security.policy: error adding Entry:
java.net.MalformedURLException.AccessControlException : access denied(java.net.SocketPermission 127.0.0.1:1099 connect,resolve)
type-3 policy file
ERROR
exception occured; java.rmi.connectexception : connection refused to host :127.0.0.1; nested exception is :
java.net.connectexception : connection refused : connect
i am trying to solve this from last week but i can't
so, please help me
