Stefano,
You can always store the LastRequestedURL somewhere either in session or
some other application scope object or also in query string. After login
is done the user can be redirected/forwarded to this LastRequestedURL.
For this there is a catch that you have to choose whether u create the
session only after login or after once the first request goes to
controller.
Query string is a best possible idea as you don't have to create
session before login is done. This choice depends upon your
architecture.
e.g. when a request for B is submitted from A, user is redirected to
login page in following,
response.sendRedirect("./login.jsp?lastRequestedURL=B");
and when login is done create a request dispatcher object on request
parameter lastRequestedURL , then forward the request to this page.
Thanx,
Rajeev

You got it. That's exactly the scenario I want to realize.
BTW there was a typo in my message. Actually the question was:
"HOW can I realize this?"
Perhaps a solution could be passing the url of the requested page to the
logon page as a request attribute, so that the logon action would know
who
to forward to.
Anyway I'd like to know if there's a better/standard way to do this or
if
there's an example to refer to.
