Help On Technologies To Be Used

I want to develope a project in opensource using struts,Ajax and other latest technologies.
Can any one tell me what all should i use to develope a good web based project using struts.
Which technology should i use for frontend validations,reporting,dynamically adding HTML row etc.

Struts is bundled with Validator framework so you don't need any special utility for front end validations.

Never did reporting, I heard something called as Jasper Reposts, Google it.

JavaScript OR any JS library, like JQuery.
