OK, I'm new but trying to learn this stuff... As I understand it: T4 exists within servlet lifespan / T5 utilizes Filter and therefore is outside the servlet lifespan.
Therefore I believe various things in T4 such as getting to the session will have to be handled differently. Is that correct? I have a fair understanding of servlet work, but very little about the context a filter has. Is there any summary of the contextual differences anywhere? Not so much the simple syntax changes in the html, but an overview of the contextual and architectural changes. A nice overview of the differences/similarities might be very helpful right now. If some of this exists please let me know. But to ask a more-simple basic question - how in T5 do we create and access a session specific Visit object? Is it simply defining something like this in the start page: @ApplicationState private Visit thisVisit; And then defining the same @ApplicationState variable in each page needing it? Thanks for any answers you can spare!
