I am new to web 2.0 and REST.I have read some articles on REST .I could understand that the REST is a design pattern and in this , every item/thing to be exposed is treated as a URL.The client will hit this URL and get the resource.
So, I am confused that a normal get request on a URL, that is send on a servlet and processed.Is this the REST way.If yes , then we are doing it since the start of coding what's new in this. If no then please explain what extra needs to be done.
Actually, I think you're pretty much correct - REST is a lot like the very first web pages a lot of us built, where a single URL corresponds to a single chunk of information. That resemblance is intentional, as REST was modeled in part on the early web.
One difference arises when you start to look at more complicated applications - instead of a multitude of pages, you get one (or a few) endpoints that you can access, each of which distributes your request to any one of many destinations.
Another difference is the restriction of actions to particular HTTP verbs - GET, in a RESTful system, for instance, is idempotent. POST is used to create a new resource. PUT is used to update an existing resource (or create a new one, in certain cases). DELETE is used to destroy an existing resource.
