Bom dia.
Estou enfrentando um problema em relação ao exercício 2 - Capitulo 6.4 - JavaServer Pages da apostila FJ21.
O exercicio solicita que eu formate uma 'Data de Nascimento' para que ela apareça no Scriplet como SimpleDateFormat("dd/MM/yyyy).
Na classe Data Acess Object no metodo getLista(), alterei de forma que a 'Data de Nascimento' seja capturada em uma String, fiz a conversão para SimpleDateFormat, instanciei uma variavel do tipo Calendar e passei como parametro a 'Data de Nascimento' já formatada no metodo setDataNascimento() do JavaBean.
Nas classes utilizadas e no JSP o Eclipse não acusa nenhum erro. Porém quando acesso o JSP no navegador, retorna a exception que declarei no web.xml.
Metodo dentro do Dao para capturar os dados do banco e retornar numa lista:
public List<Contato> getLista() throws ParseException { try { List<Contato> contatos = new ArrayList<Contato>(); PreparedStatement stmt = this.connection.prepareStatement( "SELECT * FROM contatos"); ResultSet rs = stmt.executeQuery(); while(rs.next()) { Contato contato = new Contato(); contato.setId(rs.getLong("id")); contato.setNome(rs.getString("nome")); contato.setEndereco(rs.getString("Endereco")); contato.setEmail(rs.getString("email")); String pegaData = rs.getString("dataNascimento"); Calendar dataNascimento = null; java.util.Date data = new SimpleDateFormat("dd/MM/yyyy") .parse(pegaData); dataNascimento = Calendar.getInstance(); dataNascimento.setTime(data); contato.setDataNascimento(dataNascimento); contatos.add(contato); } rs.close(); stmt.close(); return contatos; } catch(SQLException e) { throw new RuntimeException(e); } }Scriplet JSP
