solve error in connection between sql server 2008

I am trying to connect SQL server 2008 r2 with my java application using microsoft JDBC sqljdbc_4.0 driver in eclipse IDE, I goggled several time with JDBC connection between java and sql server 2008 and I have tried some of but getting same error message, So lastly am decided to put the question here with error message what am getting than, i can get know what wrong am doing?

I followed a link! link for connectivity with SQL Server and Java.

My java program:

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class Connect
{
    public static void main(String[] args) throws Exception
    {
        String userName = "Abhishek";
        String password = "abhishek-nayak";
        String url = "jdbc:sqlserver://Abhishek-VAIO\\MSSQLSERVER;databaseName=master;integratedSecurity=true";
        try
        {
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
            Connection conn = DriverManager.getConnection(url,userName,password);
            System.out.println("Connected");
        }
        catch(SQLException e)
        {
            e.printStackTrace();
        }
    }
}

my error message is:

You're using a JDBC driver that is dependent on a native SQL Server driver and need to add a path to the DLL it's dependent on (sqljdbc_auth.dll) to your library path in java.

To add this to settings of your Eclipse project (assuming you already have a SQL Server driver installed) do:

right click the project in Project Explorer -> Properties -> Java Build Path -> select sqljdbc4.jar, so it expands -> select Native library location -> Edit... -> enter <location of SQL server driver on your machine>/sqljdbc_2.0/enu/auth/x64-> OK.

Result should look like:
