Re: please help....session timeout problem!!

Fri, 23 Jun 2006 13:34:35 -0700 

Jim,
The session timeout is managed by the servlet container, i.e. Tomcat in my case. 


1) For Tomcat the session timeout is configured in web.xml.  The example 
below set the timeout to 1 hours (60 minutes).

  <session-config>
    <session-timeout>60</session-timeout>
  </session-config>


2) Can a session be renewed?  Check with the container.  This is not a 
JSF question.


3) I do not know the the problem was cause by a timed out session.

Hi,


We believe we are experiencing session timeout problems.  The project we 
are
working on consists of a Tree displaying inside of a gridsphere 
portlet.  It

works fine for about 15 minutes, and then we will be seeing a stack dump.

1.  So it there a way to make the timeout period configurable?

2.  Also, is there a way to renew a session?, and

3.  Most importantly, is our assessment of the issue correct? That is, is
the problem indeed caused by session time out?  Below is the stack dump:

An error occured!
