Pessoal pesquisei nos tópicos sobre essa apostila mas meu erro persiste, segue as informações qualquer ajuda é bem vinda.
Boa tarde pessoal,
Começando estou estudando a apostila de Java WEB da caelum mas o seguinte erro está aparecendo. Já importei o driver do mysql, alternei entre a linha comentada e comentei a de cima, mas não está dando certo oo erro do navegador é HTTP Status 500 - java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost/fj21
package br.com.caelum.jdbc;
import java.sql.Connection;
import java.sql.DriverManager;
//class conexão com o banco de dados
public class ConnectionFactory {
public Connection getConnection(){
try {
Class.forName("com.mysql.jdbc.Driver");
//DriverManager.registerDriver(new com.mysql.jdbc.Driver());
return DriverManager.getConnection("jdbc:mysql://localhost/fj21", "root", "822674");
} catch (Exception e) {
throw new RuntimeException(e);
}
}
}
