When I want to modify a table it does not work. I do this through checkboxes.



It does not generate any errors, but the tables are not updated.



form



<label class="form-check-label">
<input type="checkbox" class="form-check-input" value="${e.idEquipo}" name="idEquipo">
</label>


Servlet



String ids = request.getParameterValues("idEquipo");
DAOEquipo dEquipo = new DAOEquipo();
Date fecha = new Date();
int ids_int = new int[ids.length];

for (int i = 0; i < ids.length; i++) {
ids_int[i] = Integer.parseInt(ids[i]);
}

dEquipo.entregarEquipo(ids_int, fecha);
response.sendRedirect("/SoporteDeDispositivos/pages/equipos/entregar.jsp");


method



public boolean entregarEquipo(int equipos, java.util.Date fecha){
for (int i = 0; i < equipos.length; i++) {
String query = "UPDATE EQUIPO SET ESTADO = ?, FECHA_SALIDA = ? WHERE IDEQUIPO = ?;";
try {
PreparedStatement ps = objConn.getConn().prepareStatement(query);
ps.setString(1, "ENTREGADO");
ps.setDate(2, new Date(fecha.getTime()));
ps.setInt(3, i);

if(ps.executeUpdate() > 0){
return true;
}
} catch (SQLException ex) {
Logger.getLogger(DAOEquipo.class.getName()).log(Level.SEVERE, null, ex);
}
}
return false;
}
