Connect JSP with mysql

In this section, you will learn how to connect mysql with jsp.

Connect JSP with mysql


Create a database : First create a database named 'usermaster' in mysql. To create this database we need to run the following query in sql prompt.

mysql> create database usermaster;

This query creates database 'usermaster' in Mysql.

Connect JSP with mysql :

Now in the following jsp code, you will see how to connect with the database. First you need to copy my sql connector jar file in lib directory of your application. Name of mysql driver is passed to the forName() method of 'Class' class which loads the driver. To get the connection with the database, getConnection() method of DriverManager class is used which takes three parameters connection url, username and password.

Here is the full jsp code.

<title>Connection with mysql database</title> 
<h1>Connection status </h1>
try {
/* Create string of connection url within specified format with machine name, 
port number and database name. Here machine name id localhost and database name 
is usermaster. */ 
String connectionURL = "jdbc:mysql://localhost:3306/usermaster"; 
// declare a connection by using Connection interface 
Connection connection = null; 
// Load JBBC driver "com.mysql.jdbc.Driver". 
/* Create a connection by using getConnection() method that takes parameters of 
string type connection url, user name and password to connect to database. */ 
connection = DriverManager.getConnection(connectionURL, "root", "root");
// check weather connection is established or not by isClosed() method
