Java - URL connection does not seem to work

Question

public void enviarCadena(String s){
    s="http://192.168.1.7:36000/"+s;

    try {
        url = new URL(s);
        conexion = url.openConnection();
    } catch (MalformedURLException e) {
        e.printStackTrace();
    }catch (IOException e){

    }

}

I wrote this code. If I go to the URL in the browser, the browser sends the data to the server, but not when I execute my method in Java. The program does not throw an exception, all goes fine, but the server does not receive anything. Why?

openConnection() will not perform the call to the server. To do this, you need the connect() method:

conexion.connect();

*Sí* - what do you mean by 'not found'? – Glorfindel Jul 21 '15 at 18:25
I need this to send params to a server, but doesn't arrive to server. The conexion is OK, but not write into the server – Kevin Lopez Jul 21 '15 at 18:44

I discovered that the maximun size to POST is aprox 8MG, so not can send a big chain in one time, but i cuted and send in diferents times and it worked. I resolved with a read petition to open and comprove the send in the server. Thanks Glorfindel for your atempt for help me
