java httpclient HttpRequestRetryHandler dosn't work , how to implement retry's

[Meir Yanovich]

im trying to implement request re try's after response doesn't received i
was reading about it in the httpclient tutorial , the
HttpRequestRetryHandler does invoked only once and then it throw exception .
what i do wrong here ?

here is the code im using:
private void setRetry(int executionCount)
    {
        myRetryHandler = new HttpRequestRetryHandler() {

            public boolean retryRequest(IOException exception,int
executionCount,HttpContext context) {

                if (executionCount >= 4) {
                    // Do not retry if over max retry count
                    System.out.println("retry count");
                    return false;
                }
                if (exception instanceof NoHttpResponseException) {
                    System.out.println("NoHttpResponseException
exception");// Retry if the server dropped connection on us
                    return true;
                }
                if (exception instanceof SSLHandshakeException) {
                    // Do not retry on SSL handshake exception
                    System.out.println("SSLHandshakeException exception");
                    return false;
                }
                HttpRequest request = (HttpRequest)
context.getAttribute( ExecutionContext.HTTP_REQUEST);
                boolean idempotent = !(request instanceof
HttpEntityEnclosingRequest);
                if (idempotent) {
                    System.out.println("idempotent exception");
                    // Retry if the request is considered idempotent
                    return true;
                }
                return false;
            }

        };
    }
public  String postHttpReqest(int retries,
                                  int socketTimeoutMillis,
                                  int isSSL,
                                  String target,
                                  String url,
                                  String base_url,
                                  int port,
                                  LinkedHashMap<String, String>
lHashMapParams) throws Exception
    {


        HttpParams httpParams = new BasicHttpParams();
        HttpConnectionParams.setConnectionTimeout(httpParams, 50000);
        HttpConnectionParams.setSoTimeout(httpParams,
socketTimeoutMillis);
        defaulthttpclient = new DefaultHttpClient(httpParams);


        setRetry(retries);  // here i set the handler
        defaulthttpclient.setHttpRequestRetryHandler(myRetryHandler);

        String line = "";


        List<BasicNameValuePair> params = new ArrayList<BasicNameValuePair>();
        for (String key : lHashMapParams.keySet()) {
            String val = lHashMapParams.get(key);
            params.add(new BasicNameValuePair(key,val));

        }



        UrlEncodedFormEntity query = new UrlEncodedFormEntity(params);
        HttpPost httppost = new
HttpPost(url+":"+Integer.toString(port)+"//"+base_url);
        httppost.setEntity(query);
        HttpResponse response_ = defaulthttpclient.execute(httppost);
        HttpEntity entity = response_.getEntity();

        if (entity != null) {
            line = EntityUtils.toString(entity);
            System.out.println(line);

        }

        return line;
    }

in the server i set break point so it will hold the connection and not
return response the error im getting in the httpclient :
