what is a "client"? browser?
if the webapp has stopped, or is stopping, that means that the .war file
or WEB-INF/web.xml timestamp changed, and the webapp might be reloading.
more info would be needed for further analysis

Hi, I have a web application that uses Tomcat 5.5.15, MySQL, Torque and
ZK (a XUL/Ajax library).
If I use this application with one client all works well, but when I try
to use another client I got this exception:

I've already asked around but nobody seems to know what causes it.
Any idea?
Thanks.
