RMI- client don't work

Question

I wrote application, in it I gather all files in direction tomcat server( c:\xampp\tomcat\webapps ) in direction 'ram'. So all file are in ram direction. Server work, but client don't. In client file I have code:
import java.rmi.*;
import java.rmi.server.*;
public class ProduktKlient {
public static void main(String args[]) {
System.setProperty("java.security.policy","nowy.txt");
System.setSecurityManager(new RMISecurityManager());
String url="rmi://localhost:8080/ram/";
try{
Produkt p1=(Produkt)Naming.lookup(url+"delf");
Produkt p2=(Produkt)Naming.lookup(url+"kar");
System.out.println(p1.getOpis());
System.out.println(p2.getOpis());
}catch(Exception e) {}
}In my file nowy.txt I wrote:
grant {
permission java.net.SocketPermission "localhost:1024-65000","connect";
permission java.net.SocketPermission "localhost:8080","connect";
};I think that client don't connect with server. When I run client programm, nothing answer.
What is wrong in this application? If You want I send all aplication, but server work and objects are registry, because I try it.
Please help me.

Thanks sim085 but it don't work still.
I don't have file registry.bat. I have classpath for java 1.5 in my system Windows.
I sent you two files: ProduktClient.java and nowy.txt so I send you now another files in my direction 'ram'. I have all files in path: c:\xampp\tomcat\webapps\ram.
ProduktServer:
import java.rmi.*;
import java.rmi.server.*;
public class ProduktServer {
public static void main(String arg[]) {
   try{
   ProduktKlas p1=new ProduktKlas("Delfinek");
   ProduktKlas p2=new ProduktKlas("Karp");
   Naming.rebind("delf",p1);
   Naming.rebind("kar",p2);
    }catch (Exception e) {}
} interface Produkt.java:
import java.rmi.*;
public interface Produkt extends Remote {
String getOpis()throws RemoteException;
ProduktKlas.java:
import java.rmi.*;
import java.rmi.server.*;
public class ProduktKlas extends UnicastRemoteObject implements Produkt {
private String nazwaProduktu;
public ProduktKlas(String nazwa)throws RemoteException {
nazwaProduktu=nazwa;
public String getOpis()throws RemoteException {
return "It is name: "+nazwaProduktu;
}Of course I have file ProduktKlas_Stub.class, which I do through rmic tool.
Server work good, because when I run it, the dash char appear so it means that listen to.
Only client don't work. I run client from direction
c:\xampp\tomcat\webapps\ram>java ProduktKlient.
in my console.
Maybe is something wrong in my policy file(nowy.txt). May it file have extension .txt instead of .policy?
