I want to start a Java EE program. please help me to find the best framework to add Ajax features to my app.I want to use pure JSP and Servlet or just Struts framework and Hibernate ORM.
Use struts and check http://ajaxtags.sourceforge.net/screenshots.htmlUse eclipse - myEclipse for hibernate mapping generation.
I am using DOJO and I am happy with it.http://dojotoolkit.org/it is pure java script and you can use it any java frameworkI am using it with JSF, under apache MyFaces but it works fine with old struts.
DWR is a Java open source library which allows you to write ajax applicationyou can use it in any framework you desire.Since DWR 2.0 that support revers ajax is in milestone 2.0 I suggest use dwr 1.1.3 now until 2.0 is released.
