How to log in to VK in Java without a browser?

Question

Java

Good day, gentlemen.
I use HttpClient 4.5.1, I try to log in to VK by sending a post-request to login.vk.com/?act=login with parameters:
email
pass
ip_h
lg_h
Looks like this:

HttpPost httpPostVk= new HttpPost("http://login.vk.com/?act=login");
        List<NameValuePair> formparamsVk=new ArrayList<NameValuePair>();
        formparamsVk.add(new BasicNameValuePair("email","******"));
        formparamsVk.add(new BasicNameValuePair("pass","*******"));
       formparamsVk.add(new BasicNameValuePair("ip_h",getIp_h()));
        formparamsVk.add(new BasicNameValuePair("lg_h",getLg_h()));
        UrlEncodedFormEntity entity2 = new UrlEncodedFormEntity(formparamsVk, Consts.UTF_8);
        httpPostVk.setEntity(entity2);
        HttpResponse response = httpclient.execute(httpPostVk);
        Header[] headers= response.getAllHeaders();
        for (int i=0;i<headers.length;i++) System.out.print(headers[i]+"\r\n");

At the output I get:

Server: Apache

In theory, a redirect with a hash should be returned, but instead it turns out that the username or password is incorrect.
Apparently, I am not sending some additional parameter. What's wrong?

Answer 1

https://oauth.vk.com/token?grant_type=password&client_id=2274003&client_secret=hHbZxrka2uZ6jB1inYsH&username=LOGIN&password=PASS

And you get an eternal trusted application token with all rights. Only shh..

Answer 2

They don't do that.
To interact with VKontakte there is an API
