title: Approaches for creating REST Web services?
body: <p>i am new to REST Service development. I compared the development mechanism for both REST and WS web services and i found that you can create a WS web service using WSDL file that is the top down appraoch (Correct me if i am wrong) and using bottom up approach also, that is generating the classes manually. 
  But when it comes to REST web service development you have to follow bottom up approach only that is generating the classes manually. NetBeans IDE provides certain wizards for creating REST web service quickly from databases, entity classes and patterns. 
  I had also seen when you are developing web service in eclipse and you are using wizard in eclipse IDE, you can create a REST web service from WSDL file. I found this very strange. My question here is what are the approaches we can have for creating REST web services. Can we create REST web services using top-down and bottom up approached. If yes then please provide me details.</p>
  
  <p>Thanks. </p>
