passing an object using sessions - STRANGE???

[David Treves]

Hi there, first allow me to apologize for the complexed description...   :o)

I am trying to pass an object using the HttpSession interface. my object is:

class test
{
    int num = 5;
    String str = "this is the string";
}

I added the instance I created in the first JSP page to the session (
session.setattribute("atr") ), I made sure that session does exist when I
enter the first JSP page. I linked this page to a servlet, created an
instance of the HttpSession and tried to get the str/num of that class:

HttpSession session = request.getSession();
test foo = (test)session.getAttribute("atr");
String lala = foo.str;
out.println("sessionVar: " + lala);

I get an error ("The page cannot be displayed") because of the third line
(when I comment it, the servlet IS found and executed...).

what is wrong???

Thanks in advance!
David Treves.
