Working on the design of a web-application and since it will be a large application so can not reply on jsp include feature so have to use some other solution and for that we came up with Tiles and Sitemesh.
We are new to both of them so any insight from the community will be much appreciated.For additional information we will use Struts2.x as our mail MVC framework with Spring for the other layer(Business)
Which option is better since the application have to do with lots of content and frequent UI changes
