How do you adjust session expiration?

[Keith Kwiatek]

Hello,

I hava a JSP application that seems to time out after 10 or 15 minutes.... I
tried to edit the web.xml file with the timeout tag set to a large number,
but it gave me really strange results -the bottom line is that I can't seem
to keep the session open....

Anyone have some wisdom they can part with?
