Oracle Problem

Hi,
   I have installed Oracle 9i in my machine. I'm using WindowsNT with
SP6. I have put classes111.zip in CLASSPATH variable. The folowing code

  import java.sql.*;


public class TestSQL {
    public static void main (String [] a){
        try {
            Class.forName("oracle.jdbc.driver.OracleDriver");
             System.out.println("Driver loaded");
            Connection con =
DriverManager.getConnection("jdbc:oracle:thin:127.0.0.1@1521:sid","usern
ame","password");
            System.out.println("Connection Created");
            Statement stmt = con.createStatement();
            System.out.println("System created");
            ResultSet rs = stmt.executeQuery("Select * from tab;");
            System.out.println("Query Executed");
            while(rs.next()){
                     System.out.println(rs.getString("TNAME"));
            }
            stmt.close();
            con.close();
        }catch (Exception ex){
              ex.printStackTrace();
         }
    }
}


gives
