Guice and Wicket: using SessionScoped injections
I have a working Wicket [v6] application with Guice [v3] - I have used
dependency injection for repository operations right now and I want to
expend it into using services that are session scoped (one per user's
session). I have read through official documentation, various blog posts and
questions here, but I am not sure if I am using the correct approach.
I have two questions: 1. Do I use the correct way? 2. Do I need anything
special to run TestNG tests on classes that rely on SessionScoped
injections?
My setup: web.xml:
filter
filter-nameguiceFilter/filter-name
filter-classcom.google.inject.servlet.GuiceFilter/filter-class
/filter
filter-mapping
filter-nameguiceFilter/filter-name
url-pattern/*/url-pattern
/filter-mapping
listener
listener-classcom.xxx.CustomServletConfig/listener-class
MyApplication init:
@Override
protected void init()
{
super.init();
getResourceSettings().setResourcePollFrequency(null);
getMarkupSettings().setStripWicketTags(true);
getDebugSettings().setDevelopmentUtilitiesEnabled(true);
GuiceComponentInjector injector = new GuiceComponentInjector(this, new
WebModule(), new GuiceModule());;
}
CustomServletConfig:
public class CustomServletConfig extends GuiceServletContextListener {
@Override
protected Injector getInjector() {
return Guice.createInjector(new GuiceModule(), new WebModule());
}
WebModule:
public static class WebModule extends ServletModule {
@Override
protected void configureServlets() {
bind(WebApplication.class).toProvider(WicketGuiceAppProvider.class).asEagerSingleton();
bind(IUserService.class).to(UserService.class).in(ServletScopes.SESSION);
MapString, String params = new HashMapString, String();
params.put(WicketFilter.FILTER_MAPPING_PARAM, /*);
filter(/*).through(WicketGuiceFilter.class, params);
}
}
In an example page I have:
@Inject
IUserService userService
...
userService.doSomething
At userService.doSomething during unit test I am getting Guice
OutOfScopeException, pointing to my bindings in ServletModule: Error in
custom provider, com.google.inject.OutOfScopeException?: Cannot access
scoped object. Either we are not currently inside an HTTP Servlet request,
or you may have forgotten to apply com.google.inject.servlet.GuiceFilter? as
a servlet filter for this request.
Is my configuration ok and I need to run unit tests differently (I am simply
launching my application with WicketTester), or is my design faulty?

PropertyModel not refreshing
Hi, I have a form with labels that use PropertyModel. They work fine when I test them locally - when I click on submit button I get proper refreshed values in labels. But when I deploy my app it does not work, I still get old values. Where can be the problem? I am using Wicket 1.4.17 and deploying on Google AppEngine. My code: FormString buildHousesForm = new FormString(buildHousesForm, new ModelString()) ... ... add(new Label(houses_amount, new PropertyModel(MySession.get().getUser(), village))); ... ... -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/PropertyModel-not-refreshing-tp3877389p3877389.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Authentication and sessions - the right way?
Hi, I have a problem with designing authentication and session properly. I asked for help some time ago, but I was not able to fix the problem. I have a standard situation - I have an app that has bunch of pages and only main page with login form should be accessible for everyone. Everything else should be available after you log in. And some technical pages that should be accessible for admins only. So I want AuthenticatedApplication and AuthenticatedWebSession. I set main page with login form in Application as the page that does not need authentication. Then someone enters proper credentials and I set in Session username [key] and whole User entity (transient) with proper role. It all works fine on my computer, but when I deploy it, it stops working. Session gets detached on the way and I cannot fetche the data to my models. Yes, I keep user data in my session, I could do it with datastore queries, but session is better solution on AppEngine. And problem would still be the same pretty much. There are 2 problems, which I don't really understand: 1. Session gets detached - where is it explained when and why it happens? How should I properly initialise it? I thought that making MySession.get().(...) would be enough... When user logs in, I do MySession.get().setUser(...). Then user gets redirected to main app page, where there are labels to display data (MySession.get().getUser().getValueX(). Where is my mistake? 2. How to fetch data from Guice in Session? I have a RepositoryUser Inject, but when it is used in Session it throws nullpointer exception. Should I have it in session at all? I guess repopulating user data like that is not the best idea, I should probably just redirect him to login page again, if session somehow losses data. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Authentication-and-sessions-the-right-way-tp3866840p3866840.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Authentication and sessions - the right way?
But would it be possible to store User data in the session without having to fetch it from datastore on every request? My users don't interact with each other and they operate only on their own data. So it'd be most efficient to store User data in the session and interact with db only when some data is changed. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Authentication-and-sessions-the-right-way-tp3866840p3866866.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Authentication and sessions - the right way?
So it's normal that I lose User data when I move from login to main page and I will have to fetch it from db quite often. When will it happen? I have users browsing around my app, doing most often nothing. Plenty of labels with gets. Will browsing like that trigger fetching user data from db? Or will that data be served from cache? Whenever anything changes data will be stored in db and page will reload. Will it fetch data from db again or serve them from cache? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Authentication-and-sessions-the-right-way-tp3866840p3866875.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Authentication and sessions - the right way?
Marco: And it works without problems? There is no issue with user trying to log from 2 browser on same time, trying to cheat the system? I am just wondering if there is any risk of that. How does your code look then in session and how do you fetch your data? Martin: I was trying to save on costs, where on AppEngine you are billed for every DB query, while memcache is pretty much free. Is it really hard to keep session data in sync? Only that user can modify his data. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Authentication-and-sessions-the-right-way-tp3866840p3866906.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Users, sessions, data...
Well, my app is a game which you could call Excel, but in fantasy settings :) Modifying lots of tables and simple calculations, lots of them. Some people call that building, attacking, spellcasting... I have most of stuff atm in User entity, over 100 variables, some of them ArrayLists and HashMaps. Persistence with JDO and Guice to make things nicer. Right now I am putting whole User into session, then retrieving data from it. When user modified smth with a form, it would persist whole User to the db. Most of the time there is not much interaction - user walks around the app and looks at numbers, getting them every time from db and not from session seems ineffective. Of course consistency and workability are more important :) Smooth experience for users and no chance for bugs [ISE, blank pages, other user's data, out of order persists] is the most important thing here. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Users-sessions-data-tp3598626p3602085.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Users, sessions, data...
Hi, My last attempts to fix my session and advices here made me thinking if my approach is good. So I'm curious - how do you handle users and their data? In my case I have session, when user logs in entire entity gets loaded into session. Later I get user data from that session and when he changes anything it gets persisted to db. There is no direct interaction between user and only that user can access his data. What is your approach? :) -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Users-sessions-data-tp3598626p3598626.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Users, sessions, data...

Re: Users, sessions, data...
Well, I'm hosting it on GAE and with new pricing model I have to worry about instances, not memcache or things like that. And I don't have to do load balancing. To be sure that data does not get lost between instances [which could happen probably with big traffic and longer inactivity from user] I can just have a check in getUser() method which could reload data from db if needed. I wonder if enabling multithreading could cause problems... Loading user every time from db would be probably too slow and could spin up too many instances due to that. Right now it looks like I can get data fast from session and do a persist in 15-30ms. Add time for all calculations of course. Numbers may be different with more users though. Anyway, I'm fairly new to programming and Wicket, so I don't know what's fast or reasonable. Just trying to figure if I'm going in good direction before it's too late to change it. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Users-sessions-data-tp3598626p3599401.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Major session problem [GAE]
Hi,
I have really serious problems with my sessions - or rather getting and
displaying data with it. It works great when tested locally, but when
deployed to GAE it acts weird. In bad way. I have no idea if it's wicket or
GAE issue, but maybe I can get some hints here.
Problem is that:
- it quite often fails to load data, so when user logs it it shows blank
pages, without any data, that should com from session
[MySession.loggedInUser.get...]
- on very rare occasions it can show old values, that were changed long time
ago, some residue must be left over somewhere and is not cleaned and somehow
it can switch between
- and there was a case when one user could see data from other user [so
sessions switched?]
Of course situations 23 can never happen. Situation 1 neither - but maybe
it can be solved by some check and reload of data?
Some code to illustrate:
MySession:
public class MySession extends WebSession {
public MySession(Request request) {
super(request);
}
public boolean isAuthenticated() {
return (loggedInUser != null);
}
public static User loggedInUser;
public User getLoggedInUser() {
return loggedInUser;
}
public void setLoggedInUser(User loggedInUser) {
this.loggedInUser = loggedInUser;
}
}
In Login:
((MySession) MySession.get()).setLoggedInUser(user);
Later data is accessed by MySession.loggedInUser.[getters/setters here] and
persisted to datastore when anything changes.

Re: ArrayList, Label and Model
Ha! Good suggestion, I should have looked at this earlier. I guess I need
better understanding of how things work. this in my situation referred

Re: ArrayList, Label and Model
It's a table with lots of data to display, with a mixture of plain text,
data from session and from arrays, so it'd be rather hard to solve it with
ListView.
So my only problem is how to point the Label to data that is outside Form.

It's simple, but it gives you the idea. You'll probably need to
figure out how to do your own custom column, unless you use a list of
more complex objects (think DTOs) containing the properties you want
to display. This might be the easiest way to do what you want.

Changing it to :
private TextFieldLong hire_worker_1 = new TextFieldLong(hire_worker_1,
new ModelLong());
{
hire_worker_1.setType(Long.class);
}
Does not change anything. And is it normal that Eclipse does not let me add
anything without enclosing in { }?
BTW, is there any easy way to convert nulls to 0 when you submit empty
TextFields?

My code looks like that:
public Work() {

FormString workForm = new FormString(workForm, new
ModelString())
{
private TextFieldLong hire_worker_1 = new
TextFieldLong(hire_worker_1, new ModelLong());

}
@Override

hire_worker_1.getModelObject();
...
}
};
add(workForm);
}
Eclipse does like new MinimumValidatorLong(0), so what's the solution
for my problem?

Re: MinimumValidator and Long problem
I have nothing else really, just same more of same stuff, only a Form with
Labels, TextFields and submit method.
Anyway, deprecated NumberValidator.minimum(0) method works without any
problems, are there any disadvantages of using that?

So maybe someone could just show me working RadioChoice code with OnSubmit part? Just how to properly display it and grab data from it :) That should solve the problem, as I would compare and see what I'm doing wrong. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/RadioChoice-what-s-wrong-tp2967576p2970217.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: RadioChoice - what's wrong?
It does! Thanks a lot! I knew it was something stupid and trivial. Huh, but
it should not cause that still - I was defining TextFields in same way and
then again to add parameters and it went fine.

Hello Zeldor,
I've red your code and it seems that you define variable rc two times:
the first time as form private field and the second time just below
between braces. When onSubmit method calls rc.getModelObject() it uses
private field rc which was not initialized and so triggers a
NullPointerException. Try to remove the second type definition
RadioChoiceString and it should work.
public class Registration extends WebPage {

Re: RadioChoice - what's wrong?
Sure, but I posted pretty much everything related to radiochoice :) So I am
just not doing some obvious important steps for making RadioChoice work :)
Code, with all non-related parts removed, looks like that:
public class Registration extends WebPage {
public Registration() {
add(new FeedbackPanel(errorMsg));
//New user registration form
FormString regForm = new FormString(registrationForm,
new ModelString()) {
static final ListString NUMBERS =
Arrays.asList(new String[] { 1, 2, 3 });
private RadioChoiceString rc;
{
RadioChoiceString rc = new
RadioChoiceString(numberRadioChoice, new ModelString(),
NUMBERS).setSuffix();
add(rc.setRequired(true));
}
@Override
public void onSubmit() {
String _numbers = rc.getModelObject();
System.out.println(_numbers);
}
};
add(regForm);
}
}

RadioChoice - what's wrong?
Hi,
I am trying to get through with the very basics of Wicket - radiochoice. But
somehow I got stuck and all solutions I tried made my problems even worse...
So, what am I doing wrong?
I have this code:
static final ListString NUMBERS = Arrays.asList(new String[] { 1, 2,
3 });
private RadioChoiceString rc;
{
RadioChoiceString rc = new
RadioChoiceString(numberRadioChoice, new
ModelString(), NUMBERS).setSuffix();
add(rc.setRequired(true));
}
String _numbers = rc.getModelObject();
System.out.println(_numbers);
When I submit the form I get:
NullPointerException
What am I doing wrong then?

Best practice for DropDownChoice?
Hi, I was looking at many threads here about that matter and even more google links, after not really being able to properly use examples from Wicket in Action and few others. So I wonder - what's the best and most common way to implement DropDownChoice and map the value at the same time [well, option that'd easily work with radio buttons too]. I have seen many suggestions that were creating even few classes, then extended them, added other stuff. There must be easier solution, right? :) All I want is some displayed value [easy to localis too of course] + mapping it to int value [I am fine with creating new variable and then changing real one, instead of trying to map it to some class at once]. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Best-practice-for-DropDownChoice-tp2937257p2937257.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
