Question

my app for college work..

DOC to PDF

==

my server:

one thread per requisition

        server = new ServerSocket(5000);

        while (true) {
            Socket cliente = server.accept();
            Thread thread = new Thread(new Requisitor(cliente));
            thread.start();
        }

my class Requisitor (run method)

@Override
public void run() {
    // receive doc binary
    receive();
    // doc to pdf
    Conversor converson = new Conversor(new File("docs/"+cliente.getInetAddress().getHostAddress()+".doc"),new File("pdfs/"+cliente.getInetAddress().getHostAddress()+".pdf"));
    converson.converter();
    //response pdf binary to client
    response();
}

but the method receive() is not called.. only when i disconect client socket.

my client socket:

    Client cliente = new Client();
    cliente.connect();
    cliente.send(); // send doc binary

    boolean flag = true;

    while (flag) {
        if(!cliente.streamIsEmpty()){ // wait for conversion
            cliente.receive(); // receive pdf
            flag = false;
        }
    }


    cliente.disconect()

my receive method

        InputStream in = cliente.getInputStream();
        BufferedInputStream stream = new BufferedInputStream(in);
        FileOutputStream out = new FileOutputStream("docs/"+cliente.getInetAddress().getHostAddress()+".doc");

        byte[] buffer = new byte[1024];
        int length = 0;

        while((length = stream.read(buffer, 0, 1024)) != -1) {
            out.write(buffer, 0, length);
        }

        out.flush();
        stream.close();

any idea? 🙁

Answer 1

Here you read until -1 is returned by the stream read. This happens when the socket is closed. Try closing the OutputStream within cliente.send() (not the whole socket) after it writes the document.

    while((length = stream.read(buffer, 0, 1024)) != -1) {
        out.write(buffer, 0, length);
    }
