JDBC DataSource Configuration in Tomcat

Put a file named context.xml in META-INF folder which contains:

<?xml version="1.0" encoding="UTF-8"?>

<Context>
<Resource name="MySQLDS"
type="javax.sql.DataSource"
driverClassName="com.mysql.jdbc.Driver"
password="root"
maxIdle="2"
maxWait="5000"
username="root"
url="jdbc:mysql://localhost:3306/test"
maxActive="10"/>
</Context>

Getting the DataSource:

Context context = new InitialContext();
DataSource MYSQL_DATASOURCE = (DataSource) context.lookup("java:comp/env/MySQLDS");
