RMI и Servlet

[moon-guest]

Доброго дня форумчане!!!

Решил подружить RMI и Servlet в своем проекте, но не получается!

В RMI идет подключение к dll через native.

Если использовать как десктопное приложение то проблем нет, но Servlet упирается изо всех сил:

Клиент RMI в Servlet

    	response.setContentType("text/html;charset=UTF-8");
    	response.setHeader("Cache-Control", "no-cache");
	response.setContentType("text/html");
	response.setCharacterEncoding("UTF-8");	
    	PrintWriter out = response.getWriter();	
    	out.println("<script>");

    	Registry registry = LocateRegistry.getRegistry("localhost", 1098);
        try {
			hello stub = (hello) registry.lookup("hello");
			int Count = stub.getCount();
			for(int i=0; i < Count; i++){
				out.println("window.document.getElementById('"+
						stub.getName(i)
						+"').innerHTML="+
						stub.getData(i)
					+";");
        	}
		} catch (NotBoundException e) {
			e.printStackTrace();
		}
        
         out.println("</script>");

Сервер RMI

public class Server implements hello {
         private static JNativeMetod NativeMetod = new JNativeMetod();
         public static void main(String[] args) throws AccessException, RemoteException, AlreadyBoundException, InterruptedException {
		Server obj = new Server();
		hello stub = (hello) UnicastRemoteObject.exportObject(obj, 0);
		Registry registry = LocateRegistry.createRegistry(1098);
		registry.bind("hello", stub);
                NativeMetod.Run();
	}
        @Override
	public int getCount() throws RemoteException {
		return NativeMetod.getCount();
	}

	@Override
	public String getName(int id) throws RemoteException {
		return NativeMetod.getName(id);
	}

	@Override
	public String getData(int id) throws RemoteException {
		return NativeMetod.getData(id);
	}
}

А вообще можно ли подружить RMI и Servlet???

[moon-guest]

Всё решилось.
Оказалось что проблема была в расположении интерфейсного файла.
Он должен находиться в одинаковом пакете что на сервере то и на клиенте.
