Pessoal,
Instalei o MySQL (5.1.38 ) aqui no meu Windows Vista 64bits, adicionei o Connector do MySQL (mysql-connector-java-5.1.8-bin.jar) ao buildpath do meu projeto e estou enfrentando o seguinte problema quando tento utilizar qualquer conexão com o MySQL ocorrendo o seguinte erro:
Conectando ao banco

Minhas classes que estou utilizando para realizar o teste de conexão:
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class ConnectionFactory {
public static Connection getConnection() throws SQLException {
try {
Class.forName("com.mysql.jdbc.Driver");
System.out.println("Conectando ao banco");
return DriverManager.getConnection ("jdbc:mysql://localhost/teste", "root", "admin");
} catch (ClassNotFoundException e) {
throw new SQLException (e.getMessage());
}
}
}
import java.sql.Connection;
import java.sql.SQLException;
public class TestaConexao {
public static void main(String[] args) throws SQLException {
Connection con = ConnectionFactory.getConnection();
con.close();
}
}
Meu JDK é o 1.6.0_02.
A porta liberada no Firewall para o MySQL é a 3306 e a senha do usuário root é admin mesmo como coloquei na String de configuração da classe ConnectionFactory.
Será que comi bola ao configurar o MySQL ou o Connector está errado? Eu me lembro de ter feito esse procedimento no meu Windows Vista de 32bits à algum tempo e ele funcionou normalmente, há diferença na configuração e ou algum JDK especifico para SOs de 32bits e 64bits?
Desde já agradeço a todos!
