[Simpleweb-Support] [newbie]Why is it error??

[bagas <ba...@in...>]

Hi,
 
I have followed SIMPLE instruction making a HttpServer but how com it
doent work .
Look at what I have done ..
 
 
package demo;
 
import simple.http.load.MapperEngine;
import simple.http.serve.HandlerFactory;
import simple.http.connect.Connection;
import simple.http.connect.ConnectionFactory;
 
import java.io.IOException;
import java.net.ServerSocket;
 
public class DemoServer {
 
      public static void main(String[] list) throws IOException {
         MapperEngine engine = new MapperEngine();
         DemoHandler handler =
(DemoHandler)HandlerFactory.getInstance(engine);
         Connection connection =
ConnectionFactory.getConnection(handler);
         connection.connect(new ServerSocket(80));
      }
   }
 
 
package demo;
 
import simple.http.ProtocolHandler;
import simple.http.Response;
import simple.http.Request;
 
public class DemoHandler implements ProtocolHandler {
 
   private ProtocolHandler handler;
 
   public DemoHandler(ProtocolHandler handler) {
      this.handler = handler;
   }
 
   public void handle(Request req, Response resp) {
      resp.set("Server", "DemoServer/1.0 (Simple)");
      resp.setDate("Date", System.currentTimeMillis());
      resp.setDate("Last-Modified", System.currentTimeMillis());
      handler.handle(req, resp);
   }
}
Then I run it ...
 
javaw.exe -classpath

demo.DemoServer
 
 
java.lang.NullPointerException
            at simple.http.load.MapperEngine.<init>(Unknown Source)

How come I get this message do I have to set Context or Path .. I am
going to use Simple to make HTTPtoSMPP gateway. so I just use
ProtocolHandler.handle() to receive a HTTP request and pass a SMPP Msg
.. I do not need any Directory or Files to for this web server to work
on ...
 
 
Thank you.
