Thread: Problem sending POST request with Java..

Hey there, for some reason my post request meaning to be: http://myurl.net/index.php?nmb=random_chars_etc wont work, here's my code:

import java.util.UUID;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.URL;
import java.net.URLConnection;
import java.net.URLEncoder;
 
 
public class Main{
 
    private static String uuid = UUID.randomUUID().toString().replaceAll("-", "");
 
    public static void main(String[] args)throws Exception{
        String data = URLEncoder.encode("nmb", "UTF-8") + "=" + URLEncoder.encode("test", "UTF-8");
        URL url = new URL("http://myurl.net");
        URLConnection conn = url.openConnection();
        conn.setDoOutput(true);
        OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
        wr.write(data);
        wr.flush();
        BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
        String line;
        while ((line = rd.readLine()) != null) {
          System.out.println(line);
        }
        wr.close();
        rd.close();
    }
}

It definatlely reaches my page where I process the POST with php, however the UUID isnt sent over the url for some reason, a bit stuck..
