Re: [appengine-java] JSP code debug: Compiled JSP location in local environment
thanks, seleron! It's really help. I don't know why App docs does not point out it. Developer really needs this information. Or is there any other way to debug .jsp code efficiently? I tried to use Eclipse Debug perspective and could not find out useful information about bug in compiled code.

Re: [appengine-java] Using DataNucleus JPA - Online Quizzes Database Design
My second thought after posting previous message is to modify schema of ScoreBoar and make it a real scoreboard. Old: ScoreBoard(scoreboard_id as primary key, quizz_id as foreign key to Quizzes, 100, 90, 80, 70,60,50,40,30,20,10,0). New: ScoreBoard( identity id, quizz_id, foreign key to quizzes, user_id, foreign key to User user_score ) Table ScoreBoard has one-to-one to both table User and Quizzes. New schema would allow to post absolute value for each user and also it's easy to calculate percentage of other user's result below or above the current user's with sorting on user_score. right?

Thank you for explanation, Chau. Checking .xsd file is really a good

I have been working on this issue for hours and finally I made it worked but
I have to delete the servlet guestbook from entries in and
in web.xml. But in tutorial, it didn't mention the
deletion. It also works if I moved up the servlet sign to the first entry.
I don't understand why it behaves like this. It looks to me that doGet
method in GuestbookServet other than doPost method in SignGuestbookServlet
gets invoked immediately after a user clicks Post Greetings, which posts
data in the form. Is there a order requirement in element? Or

invocation make on servlets in section of and

Re: [appengine-java] Re: HTTP ERROR 405 with Guestbook Tutorial
Hi Chau,
I used the code in the tutorial with a slightly change. Data is posted by
POST method in the form so SignGuestbookServlet should use doPost to handle
it.
Anothe thing I am confused is that I can't see log message in Eclipse
console if I added custom message like log.info or system.out.printlin
alough I givie guestbook.level = INFO in logging.properties.
Code below is SignGuestbookServlet.java:
import com.google.appengine.api.users.UserService;
import com.google.appengine.api.users.UserServiceFactory;
public class SignGuestbookServlet {
private static final Logger log =
Logger.getLogger(SignGuestbookServlet.class.getName());
public void doPost(HttpServletRequest req, HttpServletResponse resp)
throws IOException {
UserService userService = UserServiceFactory.getUserService();
User user = userService.getCurrentUser();
String content = req.getParameter("content");
if (content == null) {
content = "(No greeting)";
}
if (user != null) {
log.info("Greeting posted by user " + user.getNickname() + ": "
+ content);
} else {
log.info("Greeting posted anonymously: " + content);
}
resp.sendRedirect("/guestbook.jsp");
}
}
Code below is guestbook.jsp:
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ page import="com.google.appengine.api.users.User" %>
<%@ page import="com.google.appengine.api.users.UserService" %>
<%@ page import="com.google.appengine.api.users.UserServiceFactory" %>
<%
UserService userService = UserServiceFactory.getUserService();
User user = userService.getCurrentUser();
if (user != null) {
%>
Hi, <%= user.getNickname() %>! (You can
sign
out.)
<%
} else {
%>
Hello!
Sign
in
to include your name with greetings you post.
<%
}
%>
