Hi i use linux and when i try to import the following packages compilation is giving error.

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;

  //generate setter and getters
}

public class SimpleURL

    {
    String postUrl="www.site.com";// put in your url
    Gson gson= new Gson();
    HttpPost post = new HttpPost(postUrl);
    StringEntity  postingString = new StringEntity(gson.toJson(pojo1));//convert your pojo to   json
    post.setEntity(postingString);
    post.setHeader("Content-type","application/json");
    HttpResponse  response = httpClient.execute(post);
    }
}
