Neither way should work at all. You need to have proper HTML 4.0
structure. JSF is no different. In the first one you have f:view in the
body but it should be AFTER the <Center> opening tag for proper HTML
structure. The second one is a really awful layout because you have f:view
at the top before the opening HTML tag but you end it completely out of order in
the BODY before a closing CENTER (followed by closing HTML tag). That is
really not good HTML structure and like I wrote I am surprised your first one
worked at all.
