Hi.
It is very interesting. I will try this.
Thank you.
Running a server-side UI framework on GAE is just bad practice, you'il be paying through the nose for extra bandwidth/cpu cycle outdated technologies like this use.
Imho if you are going GAE you should really consider GWT/Flex to make it profitable/interesting.
jsf2 outdated?? oh my god...
thanks good article!
I would like to see CDI/Weld working on GAE as well...
