alone applications (centralized/distibuted) interms of usability,
calability, portabilty, maintainability, Secutity etc. Comparision with
J2EE also a welcome thing.

helpful.so please give me useful links.

Look at InfoQ articles for ruby on rails
(Ruby on Rails) they have some pretty good articles.
Couple of articles I like are
