jdbc to my sql connectivity

This is my java code for jdbc connectivity:

import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class dbtest
{
    public static void main(String args[])throws ClassNotFoundException,SQLException
    {
        String host = "127.0.0.1.mysql.com";
        String dbName = "emp";
        int port = 3306;
        String URL = "jdbc:mysql://127.0.0.1/emp";


        try
        {
            Class.forName("jdbc:mysql://127.0.0.1/emp");           
        }
        catch (ClassNotFoundException cnfe) {
            System.out.println("Error loading driver: ");
        }


        String password = "pavilion";
        Connection connection =DriverManager.getConnection(URL,username,password);
        DatabaseMetaData dbMetaData =connection.getMetaData();
        String productName =dbMetaData.getDatabaseProductName();
        System.out.println("Database: " + productName);

        productVersion =dbMetaData.getDatabaseProductVersion();
        System.out.println("Version: " + productVersion);
        Statement statement = connection.createStatement();
        String query ="SELECT * FROM emp";
        ResultSet resultSet = statement.executeQuery(query);

        while(resultSet.next())
        {
            System.out.println(resultSet.getString(1) + " " +resultSet.getString(2));
        }
        connection.close();
    } 
}

Errors:

Error loading driver:  
 Exception in thread "main" java.sql.SQLException: No suitable driver found

instead of this

Class.forName("jdbc:mysql://127.0.0.1/emp");   

do this

Class.forName("com.mysql.jdbc.Driver");
