TCP networking with Max and Java

Hello!

I'm writing a Java application that will receive images processed through Jitter. I was planning to use [jit.net.send] to send the images (https://cycling74.com/sdk/MaxSDK-5.1.1/html/chapter_jit_networking.html).

Prior to getting into the serious stuff, I wanted to test the TCP connection between Max and a simple Java program. I am unable to get Max and Java to communicate using the Max object [mxj net.tcp.send] and a Java Socket. I've tried using UDP and it's working fine so the problem is not a network setting on my computer.

I don't know what I'm doing wrong, so any help would be welcome. Thanks!

Attached is my simple tcp test patch and here is the Java application I used to test:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;

import java.net.InetAddress;
import java.net.Socket;

public class tcpTester {

    public static void main(String args[]) {

        Socket tcpSocket = null;
        String host = "localhost";
        int port = 1234;

        System.out.println("tcpTester");

        while (tcpSocket == null) {

            try {
                tcpSocket = new Socket(host, port);
                System.out.println("Connected!");            

                if (tcpSocket.getInputStream()==null)
                    System.out.println("input stream is null");

                InputStream inputStream = tcpSocket.getInputStream();
                InputStreamReader streamReader = new InputStreamReader(inputStream);
                BufferedReader instream = new BufferedReader(streamReader);

                String message = instream.readLine();
                System.out.println("Got message: " + message);

                tcpSocket.close();    

            } catch (IOException ioe) {
                System.out.println("ioe: Unable to connect to host '" + host + "' on port " + port + ".");
                //ioe.printStackTrace();
            }
        }
    }
}
