Registration Form in JSP
For creating registration form, you must have a table in the database. You can write the database logic in JSP file, but separating it from the JSP page is better approach. Here, we are going to use DAO, Factory Method, DTO and Singletion design patterns. There are many files:
Example of Registration Form in JSP
We have created the table named user432 here.
We are having only three fields here, to make the concept clear and simplify the flow of the application. You can have other fields also like country, hobby etc. according to your requirement.
This jsp file contains all the incoming values to an object of bean class which is passed as an argument in the register method of the RegisterDao class.
This interface contains four constants that can vary from database to database.
This class is responsible to return the object of Connection. Here, driver class is loaded only once and connection object gets memory only once.
This class inserts the values of the bean component into the database.
