Hello , I have run the subscription to a data container as explained in https://wiki.eclipse.org/OM2M/one/REST_API. Now I want to implement a subscription to a python web app. Anyone can help me to do develop this? Or an explanation or the monitor.jar source code.

Thanks for your help.

Hello.
I have decoded the monitor.jar file. I have little practice in java, so if anyone can help me with an explanation of the code, it will be appreciated.

I have one question, the subscription is implemented with web sockets?

Here is the code and thanks for your help.

package httpapplication;

import com.sun.net.httpserver.HttpExchange;
import com.sun.net.httpserver.HttpHandler;
import com.sun.net.httpserver.HttpServer;
import java.io.IOException;
import java.io.InputStream;
import java.io.PrintStream;
import java.net.InetSocketAddress;

public class Monitor
{
private static int port = 1400;
private static String context = "/monitor";

public Monitor() {}

public static void main(String[] args) throws Exception { System.out.println("Starting server..");
HttpServer server = HttpServer.create(new InetSocketAddress(port), 0);
server.createContext(context, new MyHandler());
server.start();
System.out.println("The server is now listening on\nPort: " + port + "\nContext: " + context + "\n");
}

static class MyHandler implements HttpHandler {
MyHandler() {}

public void handle(HttpExchange t) throws IOException { String body = "";

try
{
InputStream is = t.getRequestBody();

int i;
while ((i = is.read()) != -1) { int i;
char c = (char)i;
body = body + c;
}
} catch (Exception e) {
e.printStackTrace();
}
System.out.println("Received notification:");
System.out.println(body);

t.sendResponseHeaders(204, -1L);
}
}
}
