我认为您可能需要在JNLP文件中请求权限。尝试添加

//==Server side==
//Thread{ 
Socket mClientSocket = cServSock.accept();
new DssServant(mClientSocket).start();
//}

DssServant(Socket socket) throws DssException {
  try {
    OutputStream mOutputStream = new BufferedOutputStream( socket.getOutputStream() );
    cObjectOutputStream = new ObjectOutputStream(mOutputStream);
    cObjectOutputStream.flush(); //publish streamHeader
    InputStream mInputStream = new BufferedInputStream( socket.getInputStream() );
    cObjectInputStream = new ObjectInputStream(mInputStream);
    ..
  } catch (IOException e) {
    ..
  }
  ..
}

//==Client side==
public RemoteSocketChannel(String host, int port, IEventDispatcher eventSubscriptionHandler) throws DssException {
  cHost = host;
  port = (port == 0 ? DssServer.PORT : port);
  try {
    cSocket = new Socket(cHost, port);

    OutputStream mOutputStream = new BufferedOutputStream( cSocket.getOutputStream() );
    cObjectOut = new ObjectOutputStream(mOutputStream);
    cObjectOut.flush(); //publish streamHeader
    InputStream mInputStream = new BufferedInputStream( cSocket.getInputStream() );
    cObjectIn = new ObjectInputStream(mInputStream);

  } catch (IOException e) {

噢,天哪

我发现了问题所在。。 从现有程序复制的servlet生成的JNLP文件提供了端口nr参数。但是端口号没有被更正。。 提供的端口是一个(现有)安全套接字。。我的应用程序使用了不安全的套接字


多么严重的错误

对不起,我没有发布Jnlp文件。。它已经包含了该设置。您可能还需要对其进行签名。
