Is DWR a MVC ??

Question

I started reading about DWR few days back. Its strikingly different from the usual web-app technologies I have worked on till date (read as huge amount of Struts). One question that invariably comes to mind is can DWR really replace MVC ? One may argue about the usability of MVC but the more mature frameworks like Struts and JSF give lots of tools in the MVC. Validation, interpretors(struts2) etc..

From whatever I have understood about DWR from my little reading and if I can put it down in few words is that its nothing but say 'RPC over HTTP'. so, Can we really replace a MVC architecture with DWR ?

Answer 1

Like you say, DWR is basically "RPC over HTTP". It is a library that makes it easy to call (server-side) Java code from (browser-side) JavaScript. It does not replace a MVC architecture (it also does not require one), any more than a logging framework or JDBC replaces (or requires) a MVC architecture.
