When you declare a bean to be in the session scope, the server sends a piece
of information to the browser that the browser then includes in all
subsequent requests. This is called a "session ID", and it's used by the
server to recognize a set of requests from the same browser as related: in
other words, as part of the same session.
This session can be ended explicitly by the application, or the JSP
container can end it after a period of user inactivity (the default value is
typically 30 minutes after the last request). After that, the session ID is
not more valid.
How can you solve it? I don't use JRun. I use Tomcat, and I don't know, but
I suppose you can change this default value. See your JRun documentation and
how to configure it.
