Hi,
If a browser window is left open for a some time while the user is logged in and the session expires, tomcat shows an ugly error message to the user. Is there a way to prevent this? Like automatically displaying a login page when the session has timed out? Please help...
Many thanks

I believe you can edit the default timeout period for a session. From BEGINNING JSP (Wrox):
"The developer can also change this timout using the setMaxInactiveInterval() method; the timeout period used by these methods is defined in seconds. If the timeout period for a session is set to -1, the session will never expire."
You can also edit your web.xml like this:
[CODE]
<webapp>
<session-config>
<session-timeout>-1</session-timeout>
</session-config>
</webapp>
[CODE]
I believe another option would be to use Tomcats built in form based log in mechanism. Then if your session times out, your are automatically sent to the login page in which you must reenter your username and password.
Hope this helps
