Connection refused (server js/ client c++)

[Matias Hernandez Arellano <ms...@archlinux.cl>]

(sorry for my english) Hi, i trying to build a little implementation where i have a C++ client and a nodejs server.

The server receive information about an image.
The client create an imagen an send to the server.

The client run the creation process in a thread inside a loop, in this loop, when a image is ready i call a thrift method to send the image to the server.

But!!.. in the server side i can't receive the data (just null) and in the client side i see an error (inside a try...catch ):Thrift: Tue May 31 10:42:45 2011 TSocket::open() connect() <Host: localhost Port: 9090>Connection refused
The connection is refused, but in both process (client/server) the same port and host is used. Sometimes (at randome) theres no connection and no error, the client just "stalt" in the thrift thread. any idea?

some code:

Server (nodejs):

    var thrift = require('thrift');
    var ImageService = require('./ImageService.js'),
       ttypes = require('./service_types.js');

    var server = thrift.createServer(ImageService,{
       receiveImage: function(image,success){
          console.log("Height: ", image.height);
          success(true);
       },
    });

    server.listen(9090);

Client (c++):

    //Constructor
    static ImageServiceClient *client;
    shared_ptr<TTransport> tr;
    StreamThread::StreamThread(Utils::CircularBuffer<cv::Mat>**buffer){
         this->bufferProcesado = *buffer;
         shared_ptr<TTransport> socket(new TSocket("localhost", 9090));
         shared_ptr<TTransport> transport(new TFramedTransport(socket));
         shared_ptr<TProtocol> protocol(new TBinaryProtocol(transport));
         client = new ImageServiceClient(protocol);
        tr = transport;
    }

   //run method of the thread
   void StreamThread::run(){
       MyImage imagen;
        while(this->bufferProcesado->actual_size()!=0){
            this->bufferProcesado->pop_back(&imagen);
            try{
                tr->open();
                ImageData data;
                data.data   = imagen.data
                data.height = imagen.height();
                data.width  = imagen.width();
                if(client->receiveImage(data))
                    std::cout << "True" << std::endl;
                else
                    std::cout << "False" << std::endl;
                tr->close();
            }catch(std::exception &e){
                std::cerr << "Error: " << e.what() << std::endl;
            }
        }
    }
