You list a bunch of technologies, each of which you plan to use for the
sample app. However, the list is not consistent because some things
listed are entire platforms, while others are simple web frameworks. If
you'rec going to do this kind of comaparison exercise, you must work
hard to compare like to like. A better list would be a table with three
columns. Something like


View Framework Middleware Persistence

JSF2 EJB JPA
Ruby on Rails ActiveRecord MySQL
Grails ? JPA?
SpringMVC Spring MySQL
Wicket ? ?
Django/Pylons ? ?
Struts2 ? ?

Please don't propagate the myths that compare "Spring" directly to
"JSF". Doing so is like comparing "Ford" with "Charger".
