But what about executing the init() method when the servlet was already
loaded?, why does this happen?
I'm getting printed the session Id, and is the same after and before
this occurs, so I suppose that the session is the same.
And the questios is that if the session was expired, I create a new
object, so is "not possible" that I get a null object, see the code:
///// BEGIN SLICE OF JAVA CODE
HttpSession sesion = request.getSession(true);
System.out.println(sesion.getId());
if (sesion.isNew()) {
control = new ControladorSesion();
sesion.setAttribute("CtlSesion",control);
}
else {
control = (ControladorSesion)sesion.getAttribute("CtlSesion");
}
..... and it fails ....:
boolean repetir = (control.getSecuencia() >= secuencia);
///// END SLICE OF JAVA CODE
thanks a lot for your time.
Bye, Dani
