But it is not good for further modifications of that project.First project i have done using jsp and mysql. i did not use servlets and MVC architecture. So i faced lot of problems to update or modify that project.after that one of my friend told me that is not good way to do project.he told me that better to use MVC. Using MVC we can know where we have to modify code. since we are using MVC we can know easily by following MVC pattern.
