我试图从桌面应用程序连接到一个URL,我得到我的问题的标题中指示的错误,但当我尝试从servlet连接到相同的URL时,一切正常.当我从浏览器加载URL时,一切正常.我在servlet中使用相同的代码.代码在库中,当它不起作用时,我将代码拉出到当前项目中的一个类,但它没有用.

代码片段.

public static String post(String urlSpec, String data) throws Exception {
    URL url = new URL(urlSpec);
    URLConnection connection = url.openConnection();
    connection.setDoOutput(true);
    OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream());
    writer.write(data);
    writer.flush();

    BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
    String line = "";
    StringBuilder builder = new StringBuilder();
    while((line = reader.readLine()) != null) {
        builder.append(line);
    }
    return builder.toString();
}   

我在这里有点困惑,是否存在一些不是普通桌面应用程序的servlet？

谢谢.

完全堆积的痕迹

我有这个方法

  private def getAddresses(data: List[Int], count: Int, len: Int): Tuple2[List[Address], List[Int]] = {
    if (count == len) {
      (List.empty, List.empty)
    } else {
      val byteAddress = data.takeWhile(_ != 0)
      val newData = data.dropWhile(_ != 0).tail
      val newCount = count + 1
      val newPosition = byteAddress.length + 1
      val destFlag = byteAddress.head
      if (destFlag == SMEAddressFlag) {
        (SMEAddress().fromBytes(byteAddress) :: getAddresses(newData, newCount, len)._1, newPosition :: getAddresses(newData, newCount, len)._2)
      } else {
        (DistributionList().fromBytes(byteAddress) :: getAddresses(newData, newCount, len)._1, newPosition :: getAddresses(newData, newCount, len)._2)
      } …
