[appengine-java] i can't understand why this simple code doens't work on local and app engine.

[배현규]

package test06;

import java.io.IOException;

import javax.servlet.http.*;

import com.google.appengine.api.users.User;
import com.google.appengine.api.users.UserService;
import com.google.appengine.api.users.UserServiceFactory;

//-XX:-UseSplitVerifier

@SuppressWarnings("serial")
public class TEST06Servlet extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws IOException {
UserService userService = UserServiceFactory.getUserService();
User user = userService.getCurrentUser();
if (user != null) {
resp.setContentType("text/html");
resp.getWriter().println("Hello, " + user.getNickname());
resp.getWriter().println("logout");
} else {

resp.sendRedirect(userService.createLoginURL(req.getRequestURI()));
}

} // doGet
} // class






code is simple. but when run this on local, app engine
both occured error. error messages are here.
