Subject RE: Problem with session
Date Mon, 08 Oct 2007 17:53:09 GMT

Java version:
Java(TM) SE Runtime Environment (build 1.6.0_01-b06)
Java HotSpot(TM) Client VM (build 1.6.0_01-b06, mixed mode)

I modified the file to receive all logs from INFO. When the
problem occurs, I see a WARN level message that says that there is no header
(custom info stored by the webapp) in session (managed by tomcat I guess)
for session id XXXX and that this is a normal condition after a server
reboot and that it will occur until the client refreshes (that is, until the
client send another type of request that initializes the header in the
session). This message comes from the webapp (I have the source code and saw
the message in it). That's why it makes me think that it has something to do
with tomcat (or the webapp) restarting alone for some reason. I'll try to
look further in the source code and try to see if the sessionid comes from
tomcat, maybe I got that wrong and that it does come from tomcat.

Where can I find the exact tomcat version?

Thank you,
