Am I correct about this?
There is nothing special about the serialization in Wicket. Wicket uses the
default Java serialization. So every field not marked as transient will be
serialized. As Martin said: watch out for non static inner classes or anon
classes because you can not see the field which is created for any reference to
something from the outer scope.
To put your stuff behind a model has a benefit: if wicket is done with your
page (response is written to the client) it will throw away anything changeable
from your models. In your case the list of the entries from your database is
flushed from memory.
I would not recommend to put long living data into your components (which then
must be serialize-able). You should put something like this into a cache.
You can put everything needed to load you date from somewhere into an model.
public class Customers extends LoadableDetachableModelListCustomer {
@SpringBean
CustomersDao dao;
public Customers() {
Injector.get().inject(this);
}
public ListCustomer load() {
return dao.allCustomers();
}
}
This way your component must not deal with anything else .. it will use model
which provides the data:)

Wicket serialization concerns
I could use some input from some of the more experienced Wicket users out there. I'm having a hard time fully understanding when to worry about Wicket attempting to serialize domain model objects, resulting in serialization warnings/errors in the logs. I had been under the impression that if I had an object as a field in a Wicket component, I needed to be on alert for serialization issues. So, if I have an object as a field, I make it a LoadableDetachableModel. In cases where I need to load in a wired object, I make use of the handy @SpringBean annotation. Otherwise, I assumed I was in the clear but I'm seeing now that's not the case. In a method within a webpage component, I'm creating a List collection of domain objects for use in a form's DropDownChoice component. Unless I put that list in a LoadableDetachableModel, I will get a serialization error. I'm led to believe that creating a reference to any of my domain classes within a Wicket component (as a field or in a method implementation) will expose me to a serialization error unless I put it in a Wicket model. Am I correct about this? Thanks! Mike Chandler
Wicket with Apache Shiro
Has anyone on this list had experience integrating Apache Shiro with their Wicket project? I've had a good deal of luck implementing the basics of Shiro security in my Wicket app, but I'm struggling with their provided caching implementation with EhCache. The cacheManager is defined as a bean in my Spring applicationContext.xml per the documentation, but I keep getting this message: Another CacheManager with same name 'cacheManager' already exists in the same VM. Please provide unique names for each CacheManager in the config or do one of following: 1. Use one of the CacheManager.create() static factory methods to reuse same CacheManager with same name or create one if necessary 2. Shutdown the earlier cacheManager before creating new one with same name. The source of the existing CacheManager is: DefaultConfigurationSource [ ehcache.xml or ehcache-failsafe.xml ] I suspect this has to do with the way Wicket behaves with my application context in general and I'm unsure what the work around is. I was wondering if anyone on this list has used Apache Shiro Security with Spring on their Wicket apps.

JUnit Tests failing after config change
In order to support the use of the @SpringBean annotation, I've made some adjustments to my Wicket application that work beautifully right out of the gate. The documentation and assistance from this list helped get me up to speed and working quickly. HOWEVER, my JUnit tests are now failing when attempting to create my Wicket application bean, as follows: Error creating bean with name 'wicketApplication' defined in class path resource [applicationContext.xml]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: javax/servlet/ServletContext Since these tests aren't Wicket specific, I can comment out the bean definition in applicationContext.xml and the tests run flawlessly, but that's certainly not an acceptable fix. The error indicates that I'm missing some dependencies (I'm guessing) but as a Maven project with Eclipse properly configured, I would think I would bomb when running the app normally and not just when running tests. Anyone have any ideas on what's going wrong here? To sum up, here are the modifications I made to make use of @SpringBean Included the following in web.xml: listener listener-classorg.springframework.web.context.ContextLoaderListener/listener-class /listener filter filter-namewicket.wicketFilter/filter-name filter-classorg.apache.wicket.protocol.http.WicketFilter/filter-class init-param param-nameapplicationFactoryClassName/param-name param-valueorg.apache.wicket.spring.SpringWebApplicationFactory/param-value /init-param /filter Referenced my primary WicketApplication class as a bean in applicationContext.xml: bean id=wicketApplication class=com.oa.frontoffice.FrontOfficeApp / And in my WicketApplication, I included the following in my init() method: getComponentInstantiationListeners().add(new SpringComponentInjector(this)); The results were great and I've been trucking along... but then I ran my unit tests and found that exception.

Unusual Serialization issue
I'm getting a serialization error when I shutdown Tomcat that has me confused.
java.io.NotSerializableException:
com.oa.frontoffice.service.AuthenticationService
I experienced quite a bit of this at first before learning that Wicket
serializes quite heavily, but gained a more thorough understanding of models
and wrap my business objects in a LoadableDetachableModel like this:
private boolean authenticate() {
LoadableDetachableModelAuthenticationService service = new
LoadableDetachableModelAuthenticationService() {
private static final long serialVersionUID = 1L;
@Override
protected AuthenticationService load() {
return new
AuthenticationService();
}
};
authMessage = service.getObject().authenticate(username,
password);
if (authMessage != SUCCESS) {
return false;
}
return true;
}
Nevertheless, invoking my custom authenticate() method above seems to trigger
this serialization exception upon shut down and I'm unsure as to why that is.
The AuthenticationService class itself makes no references to any other classes
so I don't know the root cause of this issue. If anyone has any advice on
where I might need to look, I would greatly appreciate the assistance.

I see there is a wicket-spring library and a wicket-ioc library as well. Are there any current tutorials online that you can point me to that might help me get my issues squared away?

Except if you're using converters that need access to Spring beans, e.g., services. Then, newConverterLocator() is a better place for it. 4. Within your Wicket components, tag Spring beans with an annotation: @SpringBean BeanClass beanObject; Wicket will inject the Spring bean. Of course, you need to *declare* your Spring bean in Spring! I.e., you either need to declare an application-level bean in WEB-INF/applicationContext.xml or you need to trigger annotation scanning by Spring. (context:component-scan and friends.) 5. If you need Spring beans in a behavior, resource, or any other non-component class, you need to tell Wicket about it. For that, you call Injector.get().inject(this); in that class' constructor.

Wicket Security examples
Good morning, I'm having a hard time finding some solid example implementations of Wicket Auth/Roles, specifically regarding authentication. I think the documentation on the link below is well spelled out, but it would be nice to see an example of Authentication. http://wicket.apache.org/learn/projects/authroles.html The current authentication example that is linked on that page returns a 404. Also, I'm interested in hearing anyone's insight into using Apache Shiro with Wicket. Our senior management is pretty keen on seeing us implement a security framework that has a more powerful set of features. I've found Shiro to be mostly easy to implement, with the exception of managing multiple authentication realms. I was also curious to know, considering the age of Wicket Shiro, whether or not that plug-in will work with Wicket 6.8 or if it's restricted to 1.5 or earlier. Are there any problems with Wicket Auth/Roles that might be better handled with a security framework like Apache Shiro? https://github.com/wicketstuff/core/tree/core-1.5.x/jdk-1.5-parent/shiro-security Thanks so much for any input you can offer.

RE: Forms do not reset after submit
This means that your freshly created page instance loads data from a source
which caches its data. E.g. your EntityFactory does not always return a
fresh instance.
So the first question is: how do you link to your Add a record page?
Bas,
You are definitely describing the stateful nature of the behavior I'm seeing.
I'm linking to add a record as follows:
LinkString addJobLink = new LinkString(addJobLink){
private static final long serialVersionUID = 1L;
@Override
public void onClick() {
setResponsePage(new JobAddPage());
}

Subject: Re: Forms do not reset after submit
Hi!
What you describe should only happen in certain cases:
- when you link to the page using a stored reference e.g.
in ctor:
myTargetPage = new MyTargetPage()
in click handler:
setResponsePage(myTargetPage);
This results in a single, shared page instance. The page will keep track of
state, and thus the state is shared.
- when you create a new page instance (bookmarkable or not doesn't
matter) for every click, but it's data comes from a static source (page-static,
session-based or other)
This means that your freshly created page instance loads data from a source
which caches its data. E.g. your EntityFactory does not always return a fresh
instance.
So the first question is: how do you link to your Add a record page?

Kind regards,

Good morning all! I thought I had a good handle on an issue I was having,
but it appears as though that problem is persisting. When I present a form
to the user to collect information that saves on a domain object, the form
does not reset after the form has been submitted. At first, I thought it was
related to how I link to pages, then I became convinced it was my use of a
LoadableDetachableModel. Now, after refactoring the code several times, I'm
convinced that I have over-looked something simple but I cannot figure out
what it is.
To summarize, I have a form that binds to an object as follows:
CompoundPropertyModelJob jobModel = new
CompoundPropertyModelJob((Job)
EntityFactory.getInstance().getBean(job));
jobForm.setModel(jobModel);
When the form fields are all completed and the form is submitted, the form's
onSubmit() successfully handles the submission and my implementation persists
the data to my domain object (Job) and the data is confirmed in the database.
The last line conducts a redirect to the main screen with a
setResponsePage() call.
When I click the link to add a new record to the database using the same
form, the form fields are populated with all of the same data I just entered,
suggesting to me that the previous domain object is still bound to that page
instead of refreshing and binding a clean, new instance of the Job class.
Can anyone offer any tips or suggestions on what I am doing wrong?
Best,

Fundamental forms/models issue
Good morning/afternoon everyone.
I'm having a basic problem fully deciphering how to best manage my forms,
specifically related to Models that are attached to forms. Since a Wicket
WebPage has it's constructor invoked only one time in the application
lifecycle, I'm failing to fully understand how to present a form that has a
model bound to it without inadvertently sharing that instance of the Model with
every user of the application. It seems like a fundamental issue that I'm
failing to fully grasp and could use some input.
As an example, I have the following in my constructor:
LoadableDetachableModelJob jobModel = new LoadableDetachableModelJob() {
private static final long serialVersionUID = 1L;
@Override
protected Job load() {
Job job = (Job) EntityFactory.getInstance().getBean(job);
// if we're editing an existing job, load the object
if (jobId = 1) {
job.load(jobId);
}
return job;
}
};
I later create a form and after adding it in my constructor, bind the model to
it as follows:
jobForm.setModel(new CompoundPropertyModelJob(jobModel));
As you can imagine, every user session from this point on now has that instance
of a Job object bound to that form due to these declarations being in the page
constructor. I have come a long way on my own, but I'm at a point where I
clearly do not have a full grasp of how to best approach this. I suspect I can
potentially override an instance of a Model's getObject() method for more
dynamic behavior, but I'm concerned about writing code that becomes too verbose
when perhaps there's a better/tighter way to handle this. Can anyone advise me?
Many thanks!

RE: Fundamental forms/models issue
Oh my gosh, Paul. You just nailed my problem I think.
I'm doing this:
setResponsePage(MyPage.class);
Instead of this:
setResponsePage(new MyPage());
Thanks for the link. Clearly, I have more reading to do!
Thanks all!

I think you're on the right path only one thing I would mention, the page
constructor is not called only once per application life cycle. Same page can
be constructed multiple times if you have a link going to that page and you
calll setResponsePage(new MyPage()).

RE: Fundamental forms/models issue
To conclude, my issues stemmed from not properly linking from page to page. I
did a lot of this:
BookmarkablePageLinkString(link, MyClass.class);
Instead of this:
LinkString(link) {
public void onClick() {
setResponsePage(new MyClass());
}
}
Oopsy!
I can see how the former might benefit me down the road, but not for general
use.
Thanks again everyone.

RE: Anyone using Wicket-Stuff Facebook
I also plan to use Scribe and spent a little time with it this weekend. My
particular example uses LinkedIn, but the implementations would probably be
near identical. In this particular example, I'm trying to retrieve the
Authorize URL that a user would use to authenticate with LinkedIn. The
following method returns the API hyperlink that I would use for a Login with
LinkedIn button:
private String getLinkedInAuth() {
OAuthService service = new ServiceBuilder()
.provider(LinkedInApi.class)
.apiKey(your_api_key).apiSecret(your_api_secret_hash).build();
Token requestToken = service.getRequestToken();
String link = service.getAuthorizationUrl(requestToken);
return link;
}
I haven't done much from there, but I believe you should be able to define a
return URL when a user successfully authenticates that you host (check your
Facebook app config on Facebook.com). That URL should be prepared to accept a
response that will include the user's access token which you will use to sign
any of your graph api requests.
I haven't completed my integration so hopefully I am not over simplifying.

I'm also using Scribe, Martin. I'm following up with the developer to figure
out how to use it. He has a copy and paste in his example which obviously
won't work for an actual user.

Anyone using this that can point me in the right direction on how to
use the behaviors?
I followed the example on getting a login button and it seems like
that works well, but I have no idea to tell if the user has
validated and how
to
capture that validation. Clearly it's in the behaviors section of
the

but I'm not quite sure how to use it.
Thanks.

RE: Anyone using Wicket-Stuff Facebook
Hi Stephen you should be able to define a return URL when a user successfully authenticates that you host This is the part that I don't understand. I guess I create a separate OAuth class page that launches when the user authenticates, but how I get the code out of the URL? I need the code to send back to Facebook so I can get an access token. Right. In the Scribe example, you are working in the console so a code is provided that you punch in to your console which gets consumed by a Verifier. I don't believe it will work that way in an actual seemless integration. Instead, you should be able to define a OAuth Accept Redirect URL which effectively informs Facebook to post back the credentials to that URL you specify. Here is where I am assuming since I haven't completed the integration... instead of getting an access token by sending the Verifer instance back to Facebook with the request token, Facebook should post the access token to your OAuth Accept Redirect URL which you can consume and set to a Token instance. Again, I'm assuming at this point. It's possible that your OAuth Accept Redirect URL consumes that code and then you're expected to request the access token at that point... Go to your Facebook App in the Developers console and define a URL for the OAuth Redirect URI. Put something together and try it. I believe it will send back an access token in the query string if memory serves. When I have something working, I'll gladly share it with you to provide clarification.

The other part that is confusing to me is that I had an identical JUnit test set up to do what you did above, but I'm getting an error: java.lang.UnsupportedOperationException: Unsupported operation, please use 'getAuthorizationUrl' and redirect your users there on this line Token requestToken = service.getRequestToken(); I'd be really interested to see how you implement with LinkedIn as I assume it will be very similar for my implementation.

RE: Anyone using Wicket-Stuff Facebook
The browser gets a token back that makes perfect sense and the example is
completed.
How do I consume the token? I'll play around with it a bit and let you
know what
I come up with. Thanks for the help.
Based on the path I was taking, the redirect URI is the key. Facebook
redirects as such:
YOUR_REDIRECT_URI?
access_token=USER_ACCESS_TOKEN
expires_in=NUMBER_OF_SECONDS_UNTIL_TOKEN_EXPIRES
state=YOUR_STATE_VALUE
Of course, if the request fails authentication, they redirect as follows:
YOUR_REDIRECT_URI?
error_reason=user_denied
error=access_denied
error_description=The+user+denied+your+request.
state=YOUR_STATE_VALUE
So your redirect page could start out like this:
public class FacebookResponseListener extends WebPage {
private static final long serialVersionUID = 1L;
public FacebookResponseListener(PageParameters params) {
// if there is an error, handle it
if (params.get(error_reason) != null) {
// handle the error here!
} else {
String accessToken =
params.get(access_token).toString();
int expiresIn = params.get(expires_in).toInt();
// etc... etc...
}
}
}
