What i have learned is from listening in this list.
Model 2 is setting a single entrance servlet to all your JSPs. that servlet
performs common tasks like ID user and secuity tests and then forwards the
request to the appropriate JSP/servlet, that JSP/Servlet jenerates the
HTML/content that the user sees
Model 3 adds another layer of XML. There are two variations:
JSP/Servlet generates XML, that XML gows through XSLT (usually in the
server) to what the user sees.
The other approach (and the one we are testing in our company) is XML that
are trasformed through XSLT to JSP pages, those JSP pages generate the
HTML/content that the user sees.
Both variations added a level of seperation between the UI design and the
java code.
The 1st variation has the added advantage of being more client responsive.
This means you can generate using the same JSP and XML different views
according to the user platform: browser, WAP device...
The 2nd variation has the advantage of removing the XSLT overhead from the
runtime. (and to my opinion it can also provide what the 1st variation
provides, but with more jenerated JSPs)
