One of my colleague who is having 10 years experience told me that we cannot use gwt with struts. is that true? what is the difference between these two technologies. i have some knowledge about struts but have no idea as to what gwt is and what can it do for me .
I know there's a GWT Plugin for Struts that allows interaction. It doesn't look like it's been worked on in a while, but it is not impossible for Struts and GWT to play nice.
Struts is an implementation of the Front Controller Pattern for use when developing traditional web sites/applications (by "traditional" I mean that they adhere to the HTTP request/response cycle. Struts 2 supports AJAX through plugins to access other API's like Dojo and JQuery).
