Servlet and JSP doLogin

Download the entire project here
The file exercise.rar contains JSP and Servlet code. I hope you can try this at home!
You'll see that there is only a little differencies using JSP or Servlet. I actually use the same logic for the project! If you use JSP , then the logic code will be placed in a file .jsp or if you use Servlet, your logic code will be placed in a file .class.
Sorry, I don't have enough time to explain it by detail now.
Any question? Just post a comment here or chat with me!
