Happily, that's what we're here for. What have you done, and what specific question do you hve ? Your question sounds like you posted with no work done and no clue how to do it, that's wrong, right ?

The question was there in the original revision of OP, but the question mark was missing. Anyhow, question is answered by my solution.

No question here. What answer would you expect? "I'm here for you"?

Solution 1

Using JSP pages is not at all nescessary! It makes building dynamic web pages easier, but you can also do that by using servlets alone. You'll have to do all the HTML rendering yourself via Response.Write etc. , but it's doable nevertheless.

Solution 2

Create a class library - BusinessLogic
Create a class library - DataAccess

Now, from your UI, use the object model and pass on to BusinessLogic project class. This class is a Business logic class. Do the changes as per your need here.
Now, pass on the changed data from business logic class to dataAccess project class.

For getting back data, it will be transferred from DA to BL and then BL to UI layer.

Solution 3

If you search on the internet, you will be able to find at least a few good samples (with code) that do this for you. But honestly. you should try something on your own.
