RAP, browser widget, cookies and "session timed out"? [message #658924] Thu, 10 March 2011 13:01 Go to next message

Folks;

using a RAP application and (partially) a legacy JSP/servlet based
application which is supposed to run inside a Browser widget, so far.
At the moment, the JSP/servlet application tends to keep some
information in cookies. Right now, I can launch the RAP application,
open the Browser widget (and the application in it) and do things
inside the Browser widget, by then. However, as soon as I want to do
anything else in the RAP ui by then, I end up with the infamous "server
session timed out" screen, so far lacking a real understanding why this
does happen. Can anyone enlighten me here on (a) what is happening
and/or (b) how to track it down?

TIA and all the best,
Kristian

Hi Kristian,

The "infamous server session timed out screen" is shown when the client
receives the initial HTML page for RAP as a response to an Ajax request.
This in turn happens when the server receives a request without a session
id (or some request parameters missing).

I'd suggest to track all request sent by the browser (e.g. using the
FireBug addon) and see what happens to the session id. Maybe the other
servlet changes or invalidates the session for this domain?

Hope this helps, Ralf

Hi Ralf;

and, first off, thanks a bunch for your message. Finally got some time
to peek into this again...

How does RAP on the client side keep track of the session? Using
JSESSIONID all along with jetty? If so, I have a modestly clear idea
what the problem is (RAP session id and "inner" session id overwriting
each other), but have no real idea how to change things.

Well, yes, played with Firebug and mainly saw a few cookies and session
store ids flying around, but in the end I wasn't really sure what I am
looking for to be honest. Gonna dive deeper into that the next couple
of days...

Meanwhile, thanks a bunch for your time, best regards,
Kristian
