howto redirect to login site after session expiration?
Hallo folks,
I encountered a strange behaviour regarding the population mechanics of my
forms.
Following situation: I have my app running, the browser stays open with a
html form to be filled. The http-session expires and the user submits the
form to the server. The result is a http 500 error resulting from a NPE
caused while accessing the underlying struts form to populate.
What makes me wonder is the fact that although the session expired the
request is passed through the ActionServlet, a population of the
ActionForm is attempted and of course not be completed since the session
including it's objects are already removed.
I would like to see a redirect to an error site that I specify in the
web.xml or struts-config.xml in that case. How do I ensure that
unauthenticated users or users with an expired session are redirected to
such a specified site?
TIA
Frank

Re: howto redirect to login site after session expiration?
Posted by Dakota Jack <da...@gmail.com>.
If you keep a user object in session, just check at the beginning of
the Action whether it is still with you. If not, forward to a log on
page. I assume that will work for you. If you don't have a user
object in session, whether authorized or not, then you can put a
simple String iin session saying "live" to test the session.

I'm not exactly sure what you mean above about the default behavior
creating a Sesion? I use a Filter to test for the Session and it works
fine...
in my doFilter(..) method...
HttpSession session = request.getSession(false);
if (session == null) {
response.sendRedirect(contextPath+"/sessionTimeOut.jsp");
return;
}
Why wouldn't something like the above work?
I also don't test certain paths with this filter so not all paths are
checked for a valid session (ie if they go right to the login page
obviously I don't want to test for a Session yet.)

Posted by Frank Ratzlow <ra...@adesso.de>.
okay, but handling sessions is nothing special for a certain framework. I
tend to place it some where in the container area itself, how to react on
this condition. All the feedback I got so far (thanx ;-)) leads to an own
implementation of session tracking, whatever it looks like. I was
convinced I could rely on some container capabilities.

expiration?
I am of the opinion that this is too specific a situation for a
framework to take over. I really get irritated when frameworks plug
in stuff that should be taken care of at the application level. I do
think that making code available for people that want a prepackaged
solution in a "plugin" or "application" area relating to a framework
makes sense. I have beaten this drum to death on this list, however,
with no positive response. As things are with Struts, many
application specific matters are covered (Struts upload, the
"dispatch" Action subclssses, etc.) but most (shopping cart, etc) are
not. I wish there were a set of policies and procedures on this, but
just get the usual rigamoroles when a discussion on this is attempted.
I sure would not want the framework to put something in on this, like
with file uploads, that we would then have to work around.

Re: Re: Antwort: RE: howto redirect to login site after session expiration?
Posted by Andrew Thorell <dr...@gmail.com>.
In part you are correct. You can try doing this:
in web.xml
<error-page>
<error-code> 404 </error-code>
<location>/pages/error.jsp</location>
</error-page>
This goes after <servlet-mapping> and before any <taglib> declarations.
The 404 can be replaced with any html error code you wish (as far as I know).
I'm getting an NPE error right now and the error code is 500. So you
can probably put that up. I don't use it (currently) because I like to
see the stack traces live instead of using log files to debug, but
when I release the site I put up real error pages and use web.xml.
I'm using Jboss 4.0.1sp1, so I'm making my comments on that premise,
so I can't guarentee any of my hasty generalizations will work on your
web container.
Hope this helps,
Andrew

Hi,
okay, but this leads to a solution where I do have to ensure a manuell
redirect to the appropriate site by tracking session attributes. I thought
that the container is maintaining a list of expired sessions (or at least
valid sessions to figure out invalid sessions), so that I can _configure_
(web.xml sounds like a good place) what to do in the case of an expired
session, means a session id stored in this list.
The problem with the NPE is a general prob that applies to all use cases
where the user leaves some input site open in the browser and tries to
submit it after the session timed out. The Struts framework finds no bean
with bean with the formname specified in <html:form ...> in the newly
created session so it creates a new one. Afterwards it tries to populate
the bean but the new ActionForm isn't initialized yet (object graph) so
all access to nested properties will result in a failure.
However, checking and handling expired session is IMHO very low level
stuff the container should do for me. Isn't it?

Subject: howto redirect to login site after session expiration?
Hallo folks,
I encountered a strange behaviour regarding the population mechanics of
my
forms.
Following situation: I have my app running, the browser stays open with
a
html form to be filled. The http-session expires and the user submits
the
form to the server. The result is a http 500 error resulting from a NPE
caused while accessing the underlying struts form to populate.
What makes me wonder is the fact that although the session expired the
request is passed through the ActionServlet, a population of the
ActionForm is attempted and of course not be completed since the session
including it's objects are already removed.
I would like to see a redirect to an error site that I specify in the
web.xml or struts-config.xml in that case. How do I ensure that
unauthenticated users or users with an expired session are redirected to
such a specified site?
TIA

Antwort: RE: howto redirect to login site after session expiration?
Posted by Frank Ratzlow <ra...@adesso.de>.
Hi,
unfortunately this is not an good option because the application (exactly
some of the actions) serve authorized and unauthorized users the same.
Afaik if a user sends his first request a session will be created for him
(default behaviour). Additionally we invalidate a session when a user
authorizes and store his credentials etc. in a newly created one.
I was quite sure that handling of an expired session could be done
declaratively. I feel some pain doing such a basic thing in proprietary
code. I rather think that this is something that should be handled by the
container. I just want to say, if your session expired, go to page xyz.
BTW: how can I determine via the API if a session expired? Is it possible
at all?
Regards
Frank

caused while accessing the underlying struts form to populate.
What makes me wonder is the fact that although the session expired the
request is passed through the ActionServlet, a population of the
ActionForm is attempted and of course not be completed since the session
including it's objects are already removed.
I would like to see a redirect to an error site that I specify in the
web.xml or struts-config.xml in that case. How do I ensure that
unauthenticated users or users with an expired session are redirected to
such a specified site?
TIA

RE: howto redirect to login site after session expiration?
Posted by Marco Mistroni <mm...@waersystems.com>.
Hello,
Can't you use a ServletFilter that checks if user is in the
session?
If it is not you will redirect the request to your loginpage.

Subject: howto redirect to login site after session expiration?
Hallo folks,
I encountered a strange behaviour regarding the population mechanics of
my
forms.
Following situation: I have my app running, the browser stays open with
a
html form to be filled. The http-session expires and the user submits
the
form to the server. The result is a http 500 error resulting from a NPE
caused while accessing the underlying struts form to populate.
What makes me wonder is the fact that although the session expired the
request is passed through the ActionServlet, a population of the
ActionForm is attempted and of course not be completed since the session
including it's objects are already removed.
I would like to see a redirect to an error site that I specify in the
web.xml or struts-config.xml in that case. How do I ensure that
unauthenticated users or users with an expired session are redirected to
such a specified site?
TIA
