Which serverside Java technology to use with ExtJS

Question

We are plannnig to upgrade the UI framework for our 6-8 year old application written using Struts/JSP/EJB to ExtJS. Just curious as to what is the most popular Java technology on the server people have been using. We were looking into several alternatives like

1. DWR
2. RestEasy
3. Restlet
4. Struts-Json

We are diving more towards using DWR but just wanted to know if the programming community has some food for thought on this.

For backward compatiblity reasons the migration will happen incrementally and during that period we will try to make ExtJS coexist with the old Web1.0 style pages. We are not changing anything on the business tier but just the web tier will change from JSP to ExtJs pages.

Answer 1

If you're going to use ExtJS anyway, have you considered using ExtGWT instead? That'll give you much better Java integration.
