To avoid situations when a user targets directly to view page I see
three strategies:
1. Take all your view pages under WEB-INF.
2. Use container managed security and disable access to directories
where your view pages reside (thes will be available only for
servlet dispather's forwarding/including).
3. Place a logic at the start of your view pages which checks the
calling URL and redirects/forwards to the appropriate controler
action.
Each of them has their odds but couldn't find a better solution so far.
