Olá pessoal…
Estou desenvolvendo uma aplicação com CDC utilizando a IDE NetBeans e quando tento criar a classe de conexao com o banco de dados:
classe:
public class Conexao {
private Connection connection = null;
private String serverName = "localhost";
private String mydatabase = "database";
private String url = "jdbc:mysql://" + serverName + "/" + mydatabase; // a JDBC url
private String username = "usuario";
private String password = "senha";
public Conexao() throws ClassNotFoundException, SQLException{
try{
final String driverName = "org.gjt.mm.mysql.Driver"; // MySQL MM JDBC driver
Class.forName(driverName);
connection = (Connection) DriverManager.getConnection(url, username, password);
}catch (Exception e){
e.printStackTrace();
}
}
retorna o seguinte erro:
