Sending data from node.js to Java using sockets

Question

I\'m trying to send data from node.js to Java through sockets. I searched around but nothing was really useful. I\'m used to socket.io but in this case it doesn\'t seem rea

You can use the build in socket in node.js to do something like that (very easy both in java and node.js, but you'll get the point) :

Java :

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

public class Test {

    public static void main(String[] args) {
        ServerSocket server;
        Socket client;
        InputStream input;

        try {
            server = new ServerSocket(1010);
            client = server.accept();

            input = client.getInputStream();
            String inputString = Test.inputStreamAsString(input);

            System.out.println(inputString);

            client.close();
            server.close();
        }
        catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static String inputStreamAsString(InputStream stream) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(stream));
        StringBuilder sb = new StringBuilder();
        String line = null;

        while ((line = br.readLine()) != null) {
            sb.append(line + "\n");
        }

        br.close();
        return sb.toString();
    }

}

Node.js :

var net = require('net');

var client = net.connect(1010, 'localhost');

client.write('Hello from node.js');

client.end();
