Hai Shall we check input validations in ActionServlet instead of ActionForm using validate(). If yes/No please give me explanation. and also give me explation about difference between MVC and Struts.
I am not quite sure what you are getting at with your validation question. The ActionServlet class will call the RequestProcessor class which will call the validate method on your form.
MVC is a pattern...a concept...Struts is an MVC implementation. Your question is like asking what is the difference between a car and a Honda Accord.
