Hi Captain,

I'm not sure if this error is related to your framework, but I think you can give me some input

. Seems like during a very long processing like 30mins, it invalidates my session automatically.

I am using mysql db..

Help would be much appreciated, Thanks!

Regards, Vincent

This is the normal J2EE-servlet session timeout, that you can configure in web.xml. (Also take a look into Developer's Guide.) The default is 60 minutes as far as I know...

There are two tactics:

1. define a long session timeout, e.g. 2 hours

or

2. define a short one (30 minutes) and same time embed a TIMER into the outest page that polls the server e.g. every 20 minutes, so that the session is contacted periodically

AND: please use the SESSIONCLOSER in the outest page of your application, so that the session typically is closed when the user closes the page.

Thanks, now i know

Life Saver!

Hi Captain,

I tried putting the timer on the outest page, and while heavy processing it does executes some output (system.out), but still my session is timedout on 30th minute.

Any thoughts ?

..."not possible!"... ;-)

I just checked - no problems.

Open up the Tomcat-Manager and you can observe the "inactive time" which is the relevant one for session timeout-ing. See attached screenshot.

Please note: web.xml in minutes...
Code:

   <session-config>
       <session-timeout>5</session-timeout>
       ...
   </session-config>

and duration in TIMER in milliseconds.

Do NOT use TIMER-DURATIONTYPE "lastactivity", but either use no DURATIONTYPE "lastroundtrip" of DURATIONTYPE "" (no definition).

I didn't use some long polling component, because I have some session variables that i need to get during the processing.. What happens, is the page freezes then even though I outputted some text on the server using the TIMER component, the session invalidated.

Thanks for the response Captain!
