Yes. ListaNoticias is a linkedlist that link all the news
("noticias"), and the the news class is also serializable and work
well.
What I need to know is how can the other servlet know the first
servlet's linkedList without reading it from de HardDisk.
Thanks Again

Ups, here is the rigth source:
package burrano;
import javax.servlet.*;
.
.
ListaNoticias miLista= leer();
public void init() throws ServletException
{
if (miLista == null)
{
getServletContext().setAttribute("burrano.EnviaNoticia.ListaNoticias",
leer())
}
}
public void service(HttpServletRequest req, HttpServletResponse res)
throws IOException ,ServletException
{
try
{
ObjectInputStream in = new ObjectInputStream(new
FileInputStream ("myObject"));
ListaNoticias ln = (ListaNoticias)in.readObject();
in.close();
return ln;
}
catch (IOException e13) {return new ListaNoticias();}
catch (ClassNotFoundException eg){return new ListaNoticias();}
}
