ClassCastException - problem with session timeout?

jxerxes Jul 20, 2006 8:35 AM

hello everybody and thanks for the great job you have done!

i have an application running on jboss 4.0.4.GA with seam 1.0.0.GA and myfaces 1.1.3. i've been working on this application for a while,
i'm in the test phase now. i use many converation scoped session beans
as actions for the pages and some session scoped sesson beans to encapsulate business logic which are used by the action beans. now i noticed a problem:
when a action component and the business component
it uses get invoked and the app is not used for a while i get strange errors. when i try to use a component after about 10 minutes idle time an error occurs.
after 30 minutes of idle time the same error happens when the container tries to destroy the components.

here are the exceptions (boconfirmation is the business component, loaddata is the action component):

30 minutes idle:

2. Re: ClassCastException - problem with session timeout?

hi gavin, thanks for the quick answer!

i've tried that using the JBoss annotation @CacheConfig and it works.
the default timeout of the http session is 30 minutes, thats when one error occurs so i set the idleTimeoutSeconds to above 1800 and everything was well.
but it also works with a smaller number, something above 1200 or so, i'm still testing.
is it a bug in the EJB RC8 and it is just a workaround using this long timeout for seam apps or is it usual to do so? i also posted it in the ejb forum
and another user posted a link to a jira issue.

The timeout lengths are not a bug, but I agree that they could be "optimized" ;-)

4. Re: ClassCastException - problem with session timeout?

but now when i optimize my SFSB timeouts i have a new problem.
the classcastexception occurs no more because the http session is over and the JAAS login screen appears again. when the user now logs in again the app shows not the main screen but the screen that would have been next if the session hadn't been over. this becomes a real problem when another user logs in, because he now sees the screen and data of the user that was previously logged out because of session timeout...

now it seems that the SFSBs still don't get destroyed when the session is over. but they're both annotated with @Scope(SESSION), this annotation means the http session right? if thats not the problem its maybe something with the jaas login. i've set up the security for URL like i found it here
http://www.jboss.com/index.html?module=bb&op=viewtopic&t=74300
but without logged in interceptor.
(i don't think jaas is the cause but that the SFSBs live after the http session is destroyed, so here is one of my SFSBs)

do you have an idea what i could have missed?
