What is REST?
wiki says representational state transfer is a style of software architecture for distributed hypermedia systems.. The constraints described are :
Comprised of 3 aspects - URI, MIME type supported, operations supported using HTTP methods.
Public implementations : Atom publishing protocol, Suns cloud API etc
Arent all our web applications RESTful then?
So what does it mean for a java developer?
Answers here are quite close

Everything should be treated as a resouce on the web (not a page). The clear advantage of this is that the same URL can serve content in different formats. Currently most of the sites serve html pages, but they dont work on a mobile or a client expecting xml feeds,etc.
Think of REST as a sentence
• HTTP Methods are verbs
• URIs are nouns
• This grammar is currently being abused by existing websites.
Action implied in the URI
• Implied action conflicts with HTTP method
Conflicting
GET http://addressbook/contacts/destroy/1
