    copied!<p>When I send request from JSP I use this code</p> <pre><code>&lt;%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%&gt; &lt;!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"&gt; &lt;html&gt; &lt;head&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"&gt; &lt;title&gt;Insert title here&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;form method="post" action="http://translate.intelsoft.az" id="tform" name="ftext"&gt; &lt;input class="gogo1" value="a" name="l" id="l1" /&gt; &lt;div class="il"&gt; &lt;p&gt;Rusca&lt;/p&gt; &lt;textarea class="ilkin1" name="t" id="t1" &gt; выыававыавыавыавфыа выыававыавыавыавфыа выыававыавыавыавфыа выыававыавыавыавфыа&lt;/textarea&gt; &lt;div&gt;&lt;input class="gogo" type="submit" value="Tərcümə1" name="b1" /&gt;&lt;/div&gt;&lt;/div&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>and the response is correct, so that I see my parameter's value. But when I send from Java I get no correct response. I think that the parameters are not sent correctly. Here's my Java code:</p> <pre><code>String urlParameters = "t=выыававыавыавыавфыа&amp;l=a"; String request = "http://translate.intelsoft.az"; URL url = null; try { url = new URL(request); } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); } HttpURLConnection connection = null; try { connection = (HttpURLConnection) url.openConnection(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } connection.setDoOutput(true); connection.setDoInput(true); connection.setInstanceFollowRedirects(false); try { connection.setRequestMethod("POST"); } catch (ProtocolException e) { // TODO Auto-generated catch block e.printStackTrace(); } connection.setRequestProperty("Content-Type", "text/html"); connection.setRequestProperty("charset", "utf-8"); connection.setRequestProperty("Content-Length", "" + Integer.toString(urlParameters.getBytes().length)); connection.setUseCaches (false); DataOutputStream wr; try { wr = new DataOutputStream(connection.getOutputStream ()); wr.writeBytes(urlParameters); wr.flush(); BufferedReader rd = new BufferedReader(new InputStreamReader(connection.getInputStream())); String line; while ((line = rd.readLine()) != null) { System.out.println(line); } wr.close(); connection.disconnect(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } </code></pre> <p>What is wrong here?</p>
