Tratando exceções e códigos HTTP
Olá pessoal, estou tendo o seguinte problema, eu sou iniciante em java para web utilizando html e estou seguindo a apostila da caelum, meu projeto se chama fj21-agenda, criei duas páginas em html uma se chama adiciona-contato.html e a outra se chama erro.html, eu troquei o usuário ROOT para Toor na classe ConnectionFactory, deveria aparecer a seguinte mensagem: "um erro ocorreu!", mas não aparece, mostrarei no código:
adiciona-contato.html
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Cadastro de contatos</title>
</head>
<body>
<h1>Adiciona Contatos</h1>

<form action="adicionaContato">

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
Um erro ocorreu!
</body>
</html>
e a classe ConnectionFactory (lembrando que eu troquei o usuário root de propósito)
package br.com.caelum.jdbc;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class ConnectionFactory {
public Connection getConnection() throws ClassNotFoundException{
try {
//Class.forName("com.mysql.jdbc.Driver");
DriverManager.registerDriver(new com.mysql.jdbc.Driver()); //Essa linha foi a diferença
return DriverManager.getConnection(
"jdbc:mysql://localhost/fj21", "toor", "admin");
} catch (SQLException e) {
e.printStackTrace();
throw new RuntimeException(e);
}
}
}
Por favor me ajudem

a mensagem de erro deverá aparecer realmente quando vc instanciar (utilizar) de fato essa classe.

Como assim? Eu tenho que instanciar esta classe dentro do HTML?

seu form não chama o servlet adicionaContato?
um servlet é uma classe.. é essa classe que vai processar a requisição do form.
claro, vc pode redirecionar na ConnectionFactory, mas no exemplo não é a ConnectionFactory que está sendo instanciada

oi.. calma.. não é vc, é q java é 1 pouco "diferente".
acho que seria melhor vc dominar um pouco mais as bases de java p/ depois partir p/ web..
mas basicamente, seu form envia dados, até ai ok?.. quem vai tratar esses dados é uma classe java, indicada na "action" do form..
então agora vc deverá criar a classe "adicionaContato", ok? verifique na apostila se não tem esse passo..

Ah tá, agora eu entendi, respondendo a pergunta anterior o adicionaContato é uma classe servlet, e já foi criada, pois segui passo a passo a apostila. Era pra funcionar, eu preciso criar um form no erro.html?

oi.. (achei na apostila.. aos sabados tb fico meio devagar)..
ta.. agora acho que entendi..
a adicionaContato está instanciando a contatoDAO mas é a contatoDAO que instancia a ConnectionFactory (pg 33 da minha apostila) tente inserir o redirecionamento p/ a pg de erro aqui:
foi mal.. faz tempo que n vejo servlets..

Faltou adcionar o urlPartens na anotations do servelet..
Só mais uma dica. Use as tag cod , quando for posta os codigos, pra que possa facilita o entendimento do leitor..

Esse erro e na senha de acesso , esta dando acesso negado ao usuario 'toor'. Verfique se a sua senha esta correta com a do banco e tambem o usuario.

Eu troquei o root por toor, propositalmente, pois eu criei a página erro.html para quando eu tentar gravar para aparecer a mensagem: um erro ocorreu! Eu postei o código HTML lá em cima.

oi.. se o exercicio é o da pg 71 da apostila (baixei uma versão atualizada) se vc estiver usando o Internet explorer não da certo mesmo;
comigo tb deu problema ai mudei p/ o Firefox e ok.
veja explicação aqui:
http://uaihebert.com/tratando-excecoes-em-uma-aplicacao-web/
obs: só verifique se é esse:
https://www.caelum.com.br/apostila-java-web/servlets/#5-14-exercicio-tratando-excecoes-e-codigos-http
obs. mesmo se estiver usando firefox, se estiver usando o tomcat não mexa no web.xml com o tomcat iniciado (aqui deu um "pau" danado..rs.. tive que "reinstalar"..), interrompa-o, altere o web.xml e depois reinicie.

O navegador do eclipse sempre fica dando bug , é sempre bom executa no navegador principalmente no chrome.
Vou começa a ler esta apostila hoje.
