Howdy, The servlet specification is the only authority on this, misleading books should be tossed aside. SRV.7.5 is clear, session timeout is for inactivity, not total duration, as Senor Curwen opined.
The first part of his message, using $CATALINA_HOME/conf/web.xml, I would discourage, as it's non-standard. Stick to WEB-INF/web.xml, which is standard and therefore portable across containers.
