Session timeout [message #124056] Mon, 09 March 2009 16:43 Go to next message

Hello,

I want my application works without any session timeouts. So I supposed
that if I create a service handler and implement some code in javascript,
that will request the service handler via ajax, the session will never be
terminated. But It seems this is not working.

I can suppose that I have to add some extra-code to my service function in
my service handler. Is it right? And could you please provide this code if
it possible?

Thank you,
Igor

Hi,

you should be able to use setMaxInactivateInterval on the HTTPSession .A
negative value indicates that the session should never timeout (see
javadoc).

Cheers
Benny

This is the right approach, probably just a problem in your
implementation. I am almost certain that I read on this group that
someone managed to get this working.

I think you just have to call
RWT.getRequest().getSession().setMaxInactiveInterval(-1); In your createUI
method of you EntryPoint:)

I have a simular problem:

I want to restart the application when the sessions timeout is reached.

I need some kind of session timeout event to call the workbench restart
method.

But is this method gona restart the rap session or just the workbench
inside the the rap-session. So I suppose I have to restart the complete
RAP-Session.

Do somebody know how I can do it?
The steps to solve it are:
1. Setting a Session time out (optional, I can keep the default time out)
2. Get a session time out event
3. Restart the rap-session

I dont know how to solve the steps 2 and 3.

best regards,

p-lex

Hi,


regarding step 2: you can attach a listener to the current session, try RWT.getSessionStore().addSessionStoreListener(...).
In this listener you must implement the method beforeDestroy(...). This method is called immediately before the session
is destroyed. Maybe this is what you are looking for?! I had some serious headache about the whole session thingy because
the session management is done by the underlying servlet container which makes it quite hard to cope with it sometimes...


greetings,
ben

thx for your help. The SessionStoreListener works fine. So now only the
step 3 is left to solve.

I see there is no IWorkbench#restart() method to restart the workbench.
There must be an other way to restart the session or maybe just to tell
the browser to reload the page or something like that.

I'm gonna search for a solution and post it, if not somebody else will do
it before.

Thank you,

I fix the problem. The problem was in my javascript file with ajax request
functions.

Cheers,
Igor
