Connection Class.forName

Hi list

I nedd your help I'm newbie in JDBC and my first problem is:
When I try to connect To DataBAse I have this problem:
   java.lang.ClassNotFoundException: postgresql.Driver
maybe I try with org.postgresql.Driver and error in ClassNotFoundException
I work with Linux Suse 7.2
I have installed:
    postgresql-jdbc-7.0.3-70
and I define my CLASSPATH, maybe in:
/usr/lib/pgsql/jdbc7.0-1.2.jar

my small program is:

import java.sql.*;

public class db {

   public static void main (Strings[] args){
       try{
            Class.forName("org.postgresql.Driver");
            //Class.forName("postgresql.Driver");
        }catch (Exception e){
            e.printStackTrace();
        }
   }

}

If somebody can help i will thankfull
