No suitable driver found (Mas o driver esta la !)

Question

Guys, I made a first application through the Caelum site in Java EE, a calendar, and all right, all right, fine, I added contacts to MYSQL quietly in the Java part of the workbook, the JDBC driver worked all right and so on... But when I went to Java EE, the program works perfectly, except when I click on "record", it says that no driver was found, however, I added the driver in the same way as in the Java application, by the Build path-add to build path, I don’t know what the problem is, here are the links of the lessons:

http://www.caelum.com.br/apostila-java-web/servlets/ http://www.caelum.com.br/apostila-java-web/bancos-de-dados-e-jdbc/

and my code... is updated now that the problem has been solved. Simply add the Try/catch method to the Add-On class after Class.forname which was added to the Connectionfactory class !

package minha.agenda.ozzy;

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");
            return DriverManager.getConnection(
                        "jdbc:mysql://localhost/bDados", "gabrielDados", "25120107");
        } catch(SQLException e){
            throw new RuntimeException(e);
        }
    }
}

package minha.agenda.ozzy;

import java.util.Calendar;

public class Contato {
    private Long id;
    private String nome;
    private String email;
    private String end;
    private Calendar dataNascimento;

    public Long getId(){
        return id;
    }
    public void setId(Long id){
        this.id = id;
    }

    public String getNome(){
        return nome;
    }
    public void setNome(String nome){
        this.nome = nome;
    }

    public String getEmail(){
        return email;
    }
    public void setEmail(String email){
        this.email = email;
    }

    public String getEndereco(){
        return end;
    }
    public void setEndereco(String end){
        this.end = end;
    }

    public Calendar getDataNascimento(){
        return dataNascimento;
    }
    public void setDataNascimento(Calendar dataNascimento){
        this.dataNascimento = dataNascimento;
    }
}

package minha.agenda.ozzy;

    private Connection connection;

    public ContatoDao() throws ClassNotFoundException{
        this.connection = new ConnectionFactory().getConnection();
    }
    public void adiciona(Contato contato){
        String sql = "insert into contatos"+
                    "(nome, email, endereco, dataNascimento)"+
                    "values (?,?,?,?)";

        try{
            PreparedStatement stmt = connection.prepareStatement(sql);

            stmt.setString(1,contato.getNome());
            stmt.setString(2,contato.getEmail());
            stmt.setString(3,contato.getEndereco());
            stmt.setDate(4, new Date(
                        contato.getDataNascimento().getTimeInMillis()));

            stmt.execute();
            stmt.close();
        } catch (SQLException e){
            throw new RuntimeException(e);
