This Code is working fine with simple application so the drivers are fine. so why the connection object is not able to initialise with drivers.

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.SQLException;

import java.sql.Statement;

import com.opensymphony.xwork2.ActionSupport;

public class Insert extends ActionSupport {

public String execute() throws Exception, SQLException {

	String sql = "";

	String url = "jdbc:mysql://localhost:3306/test";

	//String dbName = "test";

	String driverName = "org.gjt.mm.mysql.Driver";

	String userName = "root";

	String password = "root";

	Connection con=null;

	Statement stmt=null;

	try {

		Class.forName(driverName).newInstance();

		con = DriverManager.getConnection(url, userName, password);

		stmt = con.createStatement();

	} catch (Exception e) {

		System.out.println(e.getMessage());

	}

}
