User Registration Form in JSP

     

In this example we are going to work with a user registration page and saving the data into the database.

To store the data in the database table, create a table in which  the values will be inserted.
Now make one user registration jsp page. 

In this example we will create a simple registration form which will insert  the entered  data into the database successfully with the help of a servlet.

When submit button is clicked the data will be inserted  into the database. Firstly the registration form data will go to the controller servlet and search for the variables submitted in the form using the method getParameter() method at the request object. 

Subsequently it passes a query statement to the database to insert the data retrieved from the registration form. To stored the data into the database it uses setString() method and to retrieve the data from the database it uses the getString() method of  PreparedStatement object.

The code of the program is given below:

<body bgcolor="#999966">


<form action="/userregister/Registration " method=post>
<table cellpadding=4 cellspacing=2 border=0>
