java.net.UnknownServiceException: protocol doesn't support output
  at java.net.URLConnection.getOutputStream(Unknown Source)

程序代码如下:
URL servletURL=new URL(this.getDocumentBase(),"queryServlet");
  URLConnection connection=servletURL.openConnection();
// System.out.println(connection.getAllowUserInteraction());
  System.out.print(connection.getAllowUserInteraction());
      connection.setUseCaches(false);
      connection.setDoOutput(true);
ByteArrayOutputStream byteStream=new ByteArrayOutputStream(1024);
  PrintWriter outf=new PrintWriter(byteStream,true);
  String postData="timeStr="+URLEncoder.encode(timeStr);
  postData+="Airtimes="+URLEncoder.encode(Airtimes);
      outf.print(postData);
      outf.flush();
      String lengthString=String.valueOf(byteStream.size());
      connection.setRequestProperty("Content-length",lengthString);
      connection.setRequestProperty("Content-Type","application/x-www-form-rulencoded");
      
      
      //这句报的错误!!!
      byteStream.writeTo(connection.getOutputStream());
      BufferedReader br=new BufferedReader(new InputStreamReader(connection.getInputStream()));
      String resultStr=br.readLine();
