Bom primeiramente boa tarde a todos!
Gente estou iniciando meus estudos com servlet e JSP e o livro da caelum está me ajudando muito, mas em um exercicio não consigui passar!

Ele pede para criar um html com formulário e que quando submetidos são capiturados pelo servlet e armazenados no banco de dados no meu caso MYSQL.
Criei a classe DAO o objeto contato que recebe os dados do formulálio tudo direitinho mais quando aperto em gravar no form aparece a seguinte mensagem:

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

o servlet é esse:

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class AdicionaContatoServlet {
	
	protected void service(HttpServletRequest request, HttpServletResponse response)
			throws IOException, ServletException  {
		//busca o writer
		PrintWriter out = response.getWriter();
		
		//busca os parametros no request
		String nome = request.getParameter("nome");
		String endereco = request.getParameter("endereco");
		String email = request.getParameter("email");
		String dataEmTexto = request.getParameter("dataNascimento");
		Calendar dataNascimento = null;
		
		//fazendo a converção da data
		try {
			Date date = new SimpleDateFormat("dd/MM/yyyy").parse(dataEmTexto);
			dataNascimento = Calendar.getInstance();
			dataNascimento.setTime(date);
			
		} catch (ParseException e) {
			// TODO: handle exception
			out.println("Erro de conversão da data!");
			return; // para a execução do método
		}
		
		//Montar um objeto contato
		
		Contato contato = new Contato();
		contato.setNome(nome);
		contato.setEmail(email);
		contato.setEndereco(endereco);
		contato.setDataNascimento(dataNascimento);
		
		//salvar o contato
		ContatoDAO dao = new ContatoDAO();
		dao.Adciona(contato);
		
		//Impreime o nome do contato que foi adcionado
		
		out.println("<html>");
		out.println("<body>");
		out.println("Contato" + contato.getNome() + "adicionando com sucesso!");
		out.println("</body>");
		out.println("</html>");
				
	}//protected

}

Estou com o mesmo problema.

skalinichenko 18 de abr. de 2010

O erro:

javax.servlet.ServletException: Class br.com.caleum.agenda.servlet.AdicionaContatoServlet is not a Servlet

A sua classe não é uma servlet

public class AdicionaContatoServlet

Seria se:

public class AdicionaContatoServlet extends HttpServlet

Flw, abçs!
