Problema em fazer cadastro Simple ultilizando Toncat - Servlet e JSP

Ola pessoal, pessoal estou com problemas com Servlet,JSP, Toncat, pois eu mexia mais com Swing, agora estou aprendendo Web, e bem mais complicado para achar os erros, estou com uma difilculdade em achar os erros, por isso esperem que me ajudem, bom é o seguinte

É um cadastro de forncedor

Tenho a classe CadastroFornecedorS

package Apresentacao;

import java.io.IOException;
import java.util.List;

import javax.servlet.RequestDispatcher;
import javax.servlet.Servlet;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.swing.JOptionPane;

import Negocio.Fornecedor;
import Persistencia.FornecedorDAO;


public class CadastroFornecedorS extends HttpServlet implements Servlet {
   private static final long serialVersionUID = 1L;
    private FornecedorDAO fDAO = new FornecedorDAO();
          
   public CadastroFornecedorS() {
   }

   protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
   
      doService(request, response);
      
   }
   

   protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
      
      doService(request, response);

   }
      
   protected void doService(HttpServletRequest request, HttpServletResponse response){
      String nome  = request.getParameter("nome");
      Fornecedor fornecedor = new Fornecedor(nome);
      fDAO.save(fornecedor);
      List<Fornecedor> lst = fDAO.read();
      request.setAttribute("Lista",lst);
      RequestDispatcher rDispatcher = request.getRequestDispatcher("ListaFornecedor.jsp");
      try {
         rDispatcher.forward(request,response);
      } catch (ServletException e) {
         e.printStackTrace();
         JOptionPane.showConfirmDialog( null,"Erro ao REDIRECIONAR");
      } catch (IOException e) {
         e.printStackTrace();
         JOptionPane.showConfirmDialog( null,"Erro ao REDIRECIONAR");
      }
   
   }

}

import java.util.List;   
  
import Persistencia.FornecedorDAO;   
  
public class Teste {   
  
   public static void main(String[] args) throws Exception {   
      Fornecedor f = new Fornecedor();   
      f.setNome("pedraummmmmm");   
      FornecedorDAO fDAO = new FornecedorDAO();   
      fDAO.save(f);   
      List<Fornecedor> l = fDAO.read();   
      for(Fornecedor f1 : l){   
         System.out.println(f1.getNome());   
            
      }   
         
            
      }
