Question

I Use BufferedInputStream For HTTP POST/GET

But I Get Some Error the Below

1. java.io.FileNotFoundException: http://XX.XX.XX.XX/WebWS/data.aspx
2. Transport endpoint is not connected

Why Get This Error. My Code is Below

URL url = new URL(glob.postUrl);

    HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();

    try {

        httpConn.setDoInput(true);
        httpConn.setDoOutput(true);
        httpConn.setRequestMethod("GET");
        httpConn.setRequestProperty("Content-Type",
                "application/x-www-form-urlencoded");
        httpConn.setRequestProperty("Content-Language", "TR");      
        httpConn.setConnectTimeout(12000);


        Iterator<String> reqProps = hMap.keySet().iterator();
        while (reqProps.hasNext()) {
            String key = reqProps.next();
            String value = hMap.get(key);
            httpConn.addRequestProperty(key, value);
        }

        InputStream in = new BufferedInputStream(httpConn.getInputStream());

        StringBuilder builder = new StringBuilder();
        String line;
        try {
            BufferedReader reader = new BufferedReader(
                    new InputStreamReader(in, "UTF-8"));
            while ((line = reader.readLine()) != null) {
                builder.append(line);
            }
        } finally {
            in.close();
        }
        httpConn.disconnect();

Thanks.

Is there any reason you’re not using HttpClient?

You can replace your code with something like:

HttpContext httpContext = new BasicHttpContext();
HttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
HttpResponse response = httpClient.execute(httpGet, httpContext);
int statusCode = response.getStatusLine().getStatusCode();
HttpEntity entity = response.getEntity();
String page = EntityUtils.toString(entity);

You can setup the HttpClient with ClientConnectionManager and HttpParams for security and various http parameters for the client at initialisation (plenty of examples around if you search on class names).
