I have the following warning in Tomcat 8.5 I'm not sure I can ignore WARNING [localhost-startStop-2] org.apache.catalina.loader.WebappClassLoaderBase.clearReferencesThreads The web application [AppName] appears to have started a thread named [pool-20-thread-1] but has failed to stop it. This is very likely to create a memory leak.

我们经常在程序中发送Web请求，但是也经常在请求中出现乱码问题。下面的代码是发送请求的通用方法，但是在某些环境下中文会乱码，如何解决乱码问题呢？一开始的时候，我只想到对传入的参数进行 URLEncoder.encode(params.get("title"),"UTF-8")； 然后在服务端发现接收的数据还是乱码，根本不用解码已经乱了，后面高人指点如下： URLEncoder.encode(URLEncoder.encode(params.get("title"),"UTF-8"),"UTF-8")； 然后在服务器端如下： URLDecoder.decode(jsonvalue.get("title").toString(),"UTF-8")； 终于得到了想要的中文。 总结：网络传输时，数据会被解析两次，第一次是在网络中，第二次是在服务器。如果我们在传输网络数据的时候没有加码，那么会解析为乱码，所以我们避免中文乱码，需要加码两次，第一次是让网络解析，解析过后还是加码的所有不会乱码，到服务器在解码问题就解决了。 /** * 客户端发送HTTP请求通用POST方法 * @param url * @param params * @return * @throws Exception */ public static String postHttpRequest(String url ,

this is my first question, so please, bear with me. I have a Swing application, which gets data in a for of XML from a server through HttpURLConnection. Now I'm trying to create a constant request-respond connection with the server, to check if there are any updates for the application (as the checking has to be done regularly and often (every second or so)). In some question's comment I read that it would be better to use Apache HttpClient instead of HttpURLConnection to maintain a live connection, but I can't find any good example how to go from my current code to the one with HttpClient.

I've run into a bit of a deadend and need a bit of help (please)! I'm very new to Android Dev (and to coding in general). Basically I need to POST XML data to a URL using HttpURLConnection but can't get it to work. I've got my app reading and pasrsing XML data from a GET request but finding the POST part difficult. I've looked at creating a NameValuePair array but not sure how to do this with the XML structure I am needing to post. The XML data will look like this: <Sheet> <Job>jobNumber</Job> <Task>taskNumber</Task> <UserID>3</UserID> <Date>systemDateFormatted</Date> <Minutes>timeToLog<

I have spent half Sunday on this now I need help: I want to send a String including special chars UTF-8 encoded to a server using Java HttpURLConnection. The correct encoding of the chars fails. Example: strToSend: ä ù € strUrlEncoded: %C3%A4+%C3%B9+%E2%82%AC strReceived:ä ù ⬠My code: urlConnection = (HttpURLConnection) new URL("http://localhost:8080/NetworkingServer/ServerServlet").openConnection(); urlConnection.setUseCaches(false); urlConnection.setDoOutput(true); // Triggers POST. urlConnection.setRequestProperty("accept-charset", "UTF-8"); urlConnection.setRequestProperty("content

I have some typical codes which used HttpURLConnection to get a file with an URL. They worked fine in android 1.x and 2.x. But failed in Android 4.1! I searched on the web but found little similar information. Would anybody please help to investigate this issue? private String mURLStr; private HttpURLConnection mHttpConnection; ... url = new URL(mURLStr); ... mHttpConnection = (HttpURLConnection) url.openConnection(); mHttpConnection.setDoOutput(true); mHttpConnection.setRequestMethod("GET"); ... InputStream is = mHttpConnection.getInputStream(); The getInputStream method throws an exception:

I'm using in my android application the HttpURLConnection through a proxy where an authentication is needed. Here is my code and I will explain you after my problem. HttpURLConnection connection = null; int responseCode = -1; try { connection = (HttpURLConnection) myUrl.openConnection(); connection.setInstanceFollowRedirects(false); connection.setConnectTimeout(DEFAULT_TIMEOUT); connection.setReadTimeout(DEFAULT_TIMEOUT); responseCode = connection.getResponseCode(); System.out.println("ResponseCode = " + responseCode); } catch (IOException e) { System.out.println("Exception : " + e.getMessage(
