I've been a big of DWR (www.directwebremoting.org) in the past and have used it on a few projects. It makes AJAX easy by creating javascript proxy / stubs to java classes on the server. While DWR has been around for years it seems to have slowed down ever since the main developer moved on - it's also quite large compared to it's early d...

My current task is to migrate a J2EE application (JDK5) that is using DWR for its AJAX capability, into WebSphere Commerce platform (J2EE 1.4, JDK1.4).

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 lot...
