Actually, it's 16 lines of code in Java (ignoring whitespace):

iimport java.io.*;
import java.net.*;

public class NetEcho {

  public static void main(String[] args) throws Exception {
    ServerSocket serverSocket = new ServerSocket(8081);

    while (true) {
      byte[] data = new byte[1024];
      int actualRead = 0;
      Socket clientSocket = serverSocket.accept();
      InputStream is = clientSocket.getInputStream();

      while ((actualRead = is.read(data)) > -1)
        System.out.print(new String(data, 0, actualRead));

      clientSocket.close();
    }
  }

}
