I am new to JSP/Servlets/MVC and am writing a JSP page (using Servlets and MVC pattern) that displays information about recipies, and want the ability for users to "comment" on it too.

So for the Servlet, on doGet(), it grabs all the required info into a Model POJO and forwards the request on to a JSP View for rendering. That is working just fine.

I'd like the "comment" part to be a separate JSP, so on the RecipeView.jsp I can use to separate these views out. So I've made that, but am now a little stuck. The form in the CommentOnRecipe.jsp posts to a CommentAction servlet that handles the recording of the comment just fine. So when I reload the Recipe page, I can see the comment I just made.

I'd like to:

• Reload the page automatically after commenting (no AJAX for now)
• Block the user from making more than one comment on each Recipe over a 1 day timeframe (via a Cookie). So I store a cookie indicating the product ID whenever the user makes a comment, so we can check this later? How would it work in a MVC context?
• Show a message to the user that they have already commented on the Recipe when they visit one which they have commented on

I'm confused about using beans/including JSPs etc on how to achieve this.

I know in ASP.NET land, it would be a UseControl that I would place on a page, or in ASP.NET MVC, it would be a PartialView of some sort. I'm just confused with the way this works in a JSP/Servlets/MVC context.
