Java http file upload and server response

I've been trying to develop a desktop java app which can upload an image from local hard disk to my website and get a URL of a page dynamically created in PHP for that image. I came across HttpClient which can send a POST request, but has a lot of deprecated classes and I haven't seen how to get some information back from server besides HTTP status codes. Second approach which I am not familiar with and would really like to avoid is rebuilding a server side in JAVA.

Which would be the simplest solution for uploading a file via upload form (which is processed in PHP) and getting back some information like new URL of image to the JAVA application?

you can read the response of the POST request pretty easily (Assuming you have already uploaded the file to the server in a POST - if not check out How to upload a file using Java HttpClient library working with PHP, but i copied the critical lines here):

DefaultHttpClient httpclient = new DefaultHttpClient();
HttpPost post = new HttpPost(url);
File file = new File("c:/TRASH/zaba_1.jpg");
FileEntity reqEntity = new FileEntity(file, "binary/octet-stream");
reqEntity.setContentType("binary/octet-stream");
post.setEntity(reqEntity);
HttpResponse response = httpclient.execute(post);
HttpEntity entity = response.getEntity();
Log.d("INFO", "rcode:" + response.getStatusLine().toString());
if (response.getStatusLine().getStatusCode() - 200 >= 100)
     throw new Exception("bad status code: " + response.getStatusLine().getStatusCode());
String responseString = EntityUtils.toString(entity);

oh btw this is using

 import org.apache.http.HttpEntity;
 import org.apache.http.HttpResponse;
 import org.apache.http.client.methods.HttpPost;
 import org.apache.http.entity.StringEntity;
 import org.apache.http.impl.client.DefaultHttpClient;
 import org.apache.http.util.EntityUtils;
