I would like to get returned value from my webservice.

I have my class which Manages the HTTPRequest:

public class RatePromotions 
{
    public RatePromotions() {}
    
    public String executeHttpGet(String url) throws Exception 
    {
        BufferedReader in = null;
        try 
        {
            HttpClient client = new DefaultHttpClient();
            HttpGet request = new HttpGet();
            request.setURI(new URI(url));
            HttpResponse response = client.execute(request);
            in = new BufferedReader
            (new InputStreamReader(response.getEntity().getContent()));
            StringBuffer sb = new StringBuffer("");
            String line = "";
            String NL = System.getProperty("line.separator");
            while ((line = in.readLine()) != null) 
            {
                sb.append(line + NL);
            }
            in.close();
            
            String returnedRate = sb.toString();
            System.out.println(returnedRate);
            
            return returnedRate;
        }
        finally 
        {
            if (in != null) 
            {
                try 
                {
                    in.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}

It look likes very basic.

Then my WebService should return me : YES or NO.

I’m using it like that:

RatePromotions rating = new RatePromotions();
                String uid = Secure.getString(getContentResolver(),Secure.ANDROID_ID);
                String url = "http://developer.prixo.fr/API/RatePromo?promo="+promofrombdd.getIdentifier()+"&uid="+uid+"&rate="+"1";
                
                try {
                    if (rating.executeHttpGet(url).equals("YES"))
                    {
                        dialog.cancel();
                        Toast.makeText(TabPromotionsSingleItemActivity.this, "Promotion notee.", Toast.LENGTH_SHORT).show();
                    }
                    else
                    {
                        dialog.cancel();
                        Toast.makeText(TabPromotionsSingleItemActivity.this, "Impossible de prendre en comptre votre vote. " +
                            "Merci de réessayer.", Toast.LENGTH_LONG).show();
                    }
                } catch (Exception e) {
                    dialog.cancel();
                    Toast.makeText(TabPromotionsSingleItemActivity.this, "Impossible de prendre en comptre votre vote. " +
                        "Merci de réessayer.", Toast.LENGTH_LONG).show();
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

But it returns me just the catching thing..
