Java: a simple HTTP server sample

In JDK 6, it is very easy to create a HTTP server. Here is a sample in SDK 6.

===================================================
import java.io.IOException;
import java.io.OutputStream;
import java.net.InetSocketAddress;
import com.sun.net.httpserver.spi.HttpServerProvider;
import com.sun.net.httpserver.HttpExchange;
import com.sun.net.httpserver.HttpHandler;
import com.sun.net.httpserver.HttpServer;


public class SimpleHttpServer {

public static void main(String[] args) throws Exception{

HttpServerProvider httpServerProvider = HttpServerProvider.provider();
InetSocketAddress addr = new InetSocketAddress(8888);
HttpServer httpServer = (HttpServer)httpServerProvider.createHttpServer(addr, 1);
httpServer.createContext("/mydemo/", new MyHttpHandler());
httpServer.setExecutor(null);
httpServer.start();
System.out.println("started");

}

static class MyHttpHandler implements HttpHandler{

public void handle(HttpExchange httpExchange) throws IOException {

String response = "Hello world!";
httpExchange.sendResponseHeaders(200, response.length());
OutputStream out = httpExchange.getResponseBody();
out.write(response.getBytes());
out.close();

}

}

}
