[Wicket-user] Spring integration using AspectJ
Hi all, I'm very new to Wicket (with no more than a few hours of fly). I would like to integrate it with the spring AplicationContext/BeanFactory so I've been reading the solutions described in http://www.wicket-wiki.org.uk/wiki/index.php/Spring. I've nothing to object to them but I think it would be possible to get the integration by means of the @Configurable annotation that spring 2 offers too. This annotation injects dependencies upon bean instantiation (ie. with new) based on a prototype scope bean definition. Also from version 2.0.3 onwards this annotation would inject dependencies after deserialization as described in this jira: http://opensource.atlassian.com/projects/spring/browse/SPR-2896. So you can declare your dependencies as transient and expect them to be injected at instantiation-time and at deserialization-time. Weaving can be done at compile-time and at loading-time. If you are already using aspectj with spring, for example for domain object dependency injection, you won't need extra stuff to make it inject Wicket pages' properties. I have written a toy example of this approach and it seems to work fine. What do you think? Maybe I'm missing something. Cheers, Carlos - Take Surveys. Earn Cash.

[Wicket-user] ajax errors handling
Is there any way to control ajax errors handling? For example, if the session is expired wicket returns empty response for ajax requests (WebRequestCycleProcessor.resolve() returns an EmptyRequestTarget instance). -- Andrew Klochkov - Take Surveys.

Re: [Wicket-user] Spring integration using AspectJ
I think Igor and the others who have been working on Spring integration can answer this better, but Wicket's special sauce is that it provides proxies in order to make serialization for clustering and backbutton support as cheap as possible.

Re: [Wicket-user] Hibernate/Spring and Wicket architecture request for validation (was Wicket's questions)
My favorite way is to use the domain objects directly, but let updates (to the database) always go through services/ daos and *not* have transactions per request. I'll still use value objects every now and then because sometimes it's just easier to work with a 'flat' object that is focussed on a particular case. A small question in between.

[Wicket-user] Problem with ajax tree and listView
Hi,
This is my first time asking questions here.
Hope I can make my question clear.
I'v tried to extend the ajax tree in the wicket extension. The only
modification I made is the output value, which is a customized panel
instead of a label. Following are my html and source.
MyTree.html :
span wicket:id=indent/spana wicket:id=linkspan
wicket:id=image//a
a wicket:id=nodeLinkspan class=icon
wicket:id=icon/spanspan wicket:id=myPanel /
To simplify the problem, I strip most markups of MyPanel.html to
what I think causing the problem.
MyPanel.html :
span wicket:id=outputListspan
wicket:id=outputNamename/span/span
MyPanel.java :
public MyPanel extends Panel
{
public MyPanel(String id)
{
super(id);
ArrayListString list = new ArrayListString();
list.add(name1);
add(new ListView(outputList, list)
{
public void populateItem(final ListItem item)
{
final String name = (String) item.getModelObject();
item.add(new Label(outputName, name));
}
});
}
}
The problem is while I click the junction link,
ListView.renderItem() throws a NullPointerException. After some digging,
I found that the ListItem is null. Then I use getList(), and it
successfully return the list I passed in and the values in that list are
also correct, however the ListItem is null which I don't know why.
Thanks for reading my question. I will appreciate any suggestions.

[Wicket-user] Inner classes question
I was wondering if it is unwise to prevent the use of inner classes for models. For example a page creates a model for CheckBox that depends on a list stored in the page. In Wicket examples the list is accessed from the inner model class directly. I do not like having many inner classes in a class. What if I create a seperate model class and pass the list with it in the constructor. The final modifiers will ensure that the reference to the list cannot be changed. Will this cause the list to be serialized twice? Or will it be noticed that it is the same list. Will it cause any other problems, and if so isn't there another way to prevent the use of inner classes? Robert - Take Surveys. Earn Cash.

Re: [Wicket-user] Hibernate/Spring and Wicket architecture request for validation (was Wicket's questions)
the answer is simple: do not reattach objects. do not keep them across requests unless you have a session that is open across requests. use a detachable model that loads the objects at the beginning of the request and discards them at the end. most times these are load-by-id operations which are very well cached by hibernate so there is no performance hit on loading them every request. if you use the detached object as a formbean then use merge() to apply the changes. -igor On 3/23/07, Ivo van Dongen [EMAIL PROTECTED] wrote: My favorite way is to use the domain objects directly, but let updates (to the database) always go through services/ daos and *not* have transactions per request.

Re: [Wicket-user] Spring integration using AspectJ
there are a couple of things i personally dont like about it
1) @Configurable is a type-level annotation. so if you want any control over
what is injected you have to declare it in the applicationcontext. i have a
ton of pages and components that get injected and i would really hate to
have to maintain that in xml if i dont have to. relying on autowiring doesnt
always work because you often have two things of the same type in the
context or the fieldname doesnt match the bean name for readability
purposes.
2) you have to make the deps transient. the nice thing about wicket-spring
proxies is that you can pass injected services as if they were regular java
objects, so other components/objects can safely keep a reference to them in
any way possible. eg you can have constructs like this:
class UsersDataProvider extends SortableDataProvider {
private UserService us;
public UsersDataProvider(UserService us) { this.us=us;}
public int count() { return us.countusers(); }
...
}
just my 2c, at the end its whatever works best for you

Hi all,
I'm very new to Wicket (with no more than a few hours of fly). I would
like to integrate it with the spring AplicationContext/BeanFactory so I've
been reading the solutions described in
http://www.wicket-wiki.org.uk/wiki/index.php/Spring. I've nothing to
object to them but I think it would be possible to get the integration by
means of the @Configurable annotation that spring 2 offers too. This
annotation injects dependencies upon bean instantiation (ie. with new) based
on a prototype scope bean definition. Also from version 2.0.3 onwards this
annotation would inject dependencies after deserialization as described in
this jira: http://opensource.atlassian.com/projects/spring/browse/SPR-2896
. So you can declare your dependencies as transient and expect them to be
injected at instantiation-time and at deserialization-time. Weaving can be
done at compile-time and at loading-time. If you are already using aspectj
with spring, for example for domain object dependency injection, you won't
need extra stuff to make it inject Wicket pages' properties. I have written
a toy example of this approach and it seems to work fine. What do you think?
Maybe I'm missing something.
Cheers,
Carlos

Regarding freely passing references, I recognize I don't understand your point. If your component exposes a property for a dependency it will get it injected at instantiation-time and deserialization-time, so it won't need the dependency to be handled down to it later. And if instead the component get the dependency as an argument, it can safely use it in the context of method execution.

You get all the power of XmlApplicationContext (with which you can do more that vanilla injection) at the expense of dealing with xmls. in my apps i use a lot of panels, not just pages. so that would mean having something like 300 bean defs in xml. that is a big no thank you. I won't argue, yours is an absolutely valid point. Still there is the spring-annotations subproject that allows you to inject dependencies by simply annotating your components, besides a lot of other facilities. i wouldnt be able to do this with @Configurable because since my genericdataprovider is not @Configurable and there is no way to make it so it cannot restore its, what would have to be a transient, reference to the genericfinder.

Re: [Wicket-user] Spring integration using AspectJ
Here is an example of using @Configurable to integrate spring with wicket as some people has asked me for one. To launch it just: 1) set MAVEN_OPTS=-javaagent:path-to-aspectwaver.jar/aspectjweaver.jar in the env. 2) run 'mvn jetty:run' Notice that dependencies are injected *after* constructor execution, so for this simple toy page that just get a text message from its only dependency, it could seem a little contrived to setup a read only Model just for feeding that message. More realistic scenarios generally will put a dao behind a model so the dependency won't be directly needed at construction time but instead when model callbacks are called.

Re: [Wicket-user] Spring integration using AspectJ
heh, the biggest advantage of @SpringBean is that it is done _before_ the
constructor. i use services in the constructor all the time. maybe you can
tweak the aspectj aspect to also do it before as well.
(But do you explicitly invoke these services from inside the constructor or
just delay execution inside populateItem-like callbacks? Sorry if the
question is silly but I'm still making my way into wicket.)
Regarding tweaking the aspect, the off-the-shelf pointcut is an
initialization one and the advice is an after one. Initialization pointcut
will encompass the period from the return from the super constructor call to
the return of the first-called constructor. So the advice will in fact be
called after the constructor returns. But redefining the advice to
before-initialization (or before-call or before-execution) is trivial:
@Aspect
public class ConfigurerAspect extends BeanConfigurerSupport {
public ConfigurerAspect() {
setBeanWiringInfoResolver(new AnnotationBeanWiringInfoResolver());
}
@Before(initialization((@

public void beanCreation(Object bean) {

}
Then you will need to replace aop:spring-configured for bean class=
toy.ConfigurerAspect factory-method=aspectOf/ in your application
context.
The same can be done for matching your generic data providers but using
ClassNameBeanWiringInfoResolver and a different pointcut instead.
I've attached the example modified with the custom aspect.

[Wicket-user] General Java/OO/Pattern Question
As the subject indicates, this isn't a question specific to Wicket (although
it WILL eventually involve Wicket to display these objects), so if you feel
I should post this elsewhere, feel free to tell me so, however it seemed
like a pretty bright bunch of Java guys hang around here so I'm hoping for
some insight.
I've been tasked with implementing a rather curious (to me anyway)
hierarchical object structure. Most of the objects in this structure serve
no other purpose than to group the objects below them; it's only at the
final leaf levels that there are some significant behavioral difference in
the objects. For lack of a better example, I'll call these objects Grouper1,
Grouper2, Grouper3, and Leaf. So I might have a structure that looks like:
Grouper1
--Grouper2
Grouper3
--Leaf
--Leaf
--Leaf
Grouper3
--Leaf
--Leaf
--Leaf
It can also look like this:
Grouper1
--Grouper3
Leaf
Leaf
Leaf
--Grouper3
Leaf
Leaf
Leaf
Or like this:
Grouper1
--Leaf
--Leaf
--Grouper2
Grouper3
--Leaf
--Leaf
--Leaf
Grouper3
--Leaf
--Leaf
--Leaf
Or even like this:
Grouper3
--Leaf
--Leaf
--Leaf
Although I'm willing to exclude that last example (with something other than
a Grouper1 at the top) if it helps simplify things any.
As you can see almost all objects in the hierarchy can exist at any level.
Only the leaf node has any properties beyond those shared by all of the
other objects. And before you ask, despite the fact that the branch items
are so similar, they do have different labels that are important to the
people using the hierarchy. I'm just trying to determine if those labels are
important to the domain model.
I started to model this using simple inheritance. Something like the
following:
public abstract class MyHierarchyObject{
private String commonAttribute1;
private boolean commonAttribute2 = false;
private ListMyHierarchyObject children = new
ArrayListMyHierarchyObject;
private MyHierarchyObject parent; //the association needs to be
bidirectional for up and down navigation
...
}
public class Grouper1 extends MyHierarchyObject{
}
etc. etc.
Of course, I realized after just a few seconds that this seemed a little
silly since I was going to end up with at least three classes with either no
behavior or properties or only extremely minor changes to the abstract
class's properties like setting commonAttribute2 to true by default.
So does using inheritance like this still make sense or should I do
something like make the MyHierarchyObject not abstract and add a Type
property that can be populated from an enum with elements like Grouper1,
Grouper2, and Grouper3? What about the leaf node. It's not allowed to have
children but because it can be a child of any of the Groupers, it seems like
it needs to extend MyHierarchyObject in order to fit into the child parent
model. Should I put the children related methods into an interface that only
the Grouper classes implement? Of course that only works if I use the
inheritance model; maybe that's a good reason to use it? Or is there a
design pattern I'm missing in all of this that might help me.
I've been thinking about this for so long now that I'm afraid I'm too deep
into it and not thinking clearly about the best approaches. That's why I'm
posting here. Unfortunately, the hierarchy is quite a bit more complex than
this example, but I think if I can solve this level of complexity, I can
apply similar logic to the rest of the hierarchy that I didn't represent
here.
Thanks for reading such a long post.

It's cool that it can be done like that. However, it's still not clear
to me what the advantage (besides giving people more choice if they

Also, forgive me if I missed something, but if those dependencies are

Re: [Wicket-user] Spring integration using AspectJ
thats why you use the aspectj weaver/loader, it weaves a deserialization
handler into the object to reinject the dependencies.

It isn't clear to me either. But as I know of some people (including myself)
that i's using @Configurable to inject their domain objects (this is the
spring 2 recommended way to go with that kind of wizardry), they may prefer
to reutilize the same general technique for their presentation layer.
Also, forgive me if I missed something, but if those dependencies are

Take a look at
http://opensource.atlassian.com/projects/spring/browse/SPR-2896. The toy
aspect I have defined before won't take care of dependency injecting upon
deserialization, but it's a matter of advicing readResolve too as have been
done for the spring 2.0.3 AnnotationBeanConfigurerAspect; it's pretty easy,
I'll post the updated aspect later.

But if i integrate the html in a Wicket page, only the static content of the flash app is displayed, and Wicket generates errors : 2007-03-23 22:24:18,832 [http--Processor24] ERROR wicket.RequestCycle - Unable to load class with name: eu.kwark.main.settings.xml wicket.WicketRuntimeException: Unable to load class with name: eu.kwark.main.settings.xml at wicket.application.DefaultClassResolver.resolveClass(DefaultClassResolver.java:66) at wicket.request.target.coding.PackageRequestTargetUrlCodingStrategy.decode(PackageRequestTargetUrlCodingStrategy.java:82) at wicket.protocol.http.request.WebRequestCodingStrategy.targetForRequest(WebRequestCodingStrategy.java:331) at wicket.request.compound.DefaultRequestTargetResolverStrategy.resolve(DefaultRequestTargetResolverStrategy.java:83) at wicket.request.compound.AbstractCompoundRequestCycleProcessor.resolve(AbstractCompoundRequestCycleProcessor.java:48) at wicket.RequestCycle.step(RequestCycle.java:992) at wicket.RequestCycle.steps(RequestCycle.java:1084) at wicket.RequestCycle.request(RequestCycle.java:454) at wicket.protocol.http.WicketServlet.doGet(WicketServlet.java:219) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:869) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:664) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:80) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684) at java.lang.Thread.run(Thread.java:595) (eu.kwark.main is the package where i stored all the flash related files) Can someone show me the way, please ? - Take Surveys.

Re: [Wicket-user] General Java/OO/Pattern Question
You need an interface like javax.swing.tree.TreeNode that all your
nested objects implement. This is what wicket uses for its tree
implementation (take a look in wicket-extensions for 1.x). The wicket
tree impl rocks, so you can do no better than look there for
inspiration. Also, take a look at DefaultMutableTreeNode for ideas on
how to implement.

--Leaf
--Leaf
--Grouper2
Grouper3
--Leaf
--Leaf
--Leaf
Grouper3
--Leaf
--Leaf
--Leaf
Or even like this:
Grouper3
--Leaf
--Leaf
--Leaf
Although I'm willing to exclude that last example (with something other than
a Grouper1 at the top) if it helps simplify things any.
As you can see almost all objects in the hierarchy can exist at any level.
Only the leaf node has any properties beyond those shared by all of the
other objects. And before you ask, despite the fact that the branch items
are so similar, they do have different labels that are important to the
people using the hierarchy. I'm just trying to determine if those labels are
important to the domain model.
I started to model this using simple inheritance. Something like the
following:
public abstract class MyHierarchyObject{
private String commonAttribute1;
private boolean commonAttribute2 = false;
private ListMyHierarchyObject children = new
ArrayListMyHierarchyObject;
private MyHierarchyObject parent; //the association needs to be
bidirectional for up and down navigation
...
}
public class Grouper1 extends MyHierarchyObject{
}
etc. etc.
Of course, I realized after just a few seconds that this seemed a little
silly since I was going to end up with at least three classes with either no
behavior or properties or only extremely minor changes to the abstract
class's properties like setting commonAttribute2 to true by default.
So does using inheritance like this still make sense or should I do
something like make the MyHierarchyObject not abstract and add a Type
property that can be populated from an enum with elements like Grouper1,
Grouper2, and Grouper3? What about the leaf node. It's not allowed to have
children but because it can be a child of any of the Groupers, it seems like
it needs to extend MyHierarchyObject in order to fit into the child parent
model. Should I put the children related methods into an interface that only
the Grouper classes implement? Of course that only works if I use the
inheritance model; maybe that's a good reason to use it? Or is there a
design pattern I'm missing in all of this that might help me.
I've been thinking about this for so long now that I'm afraid I'm too deep
into it and not thinking clearly about the best approaches. That's why I'm
posting here. Unfortunately, the hierarchy is quite a bit more complex than
this example, but I think if I can solve this level of complexity, I can
apply similar logic to the rest of the hierarchy that I didn't represent
here.
Thanks for reading such a long post.

It's cool that it can be done like that. However, it's still not clear to me what the advantage (besides giving people more choice if they It isn't clear to me either. But as I know of some people (including myself) that i's using @Configurable to inject their domain objects (this is the spring 2 recommended way to go with that kind of wizardry), they may prefer to reutilize the same general technique for their presentation layer. Yeah, that's a good point. Also, forgive me if I missed something, but if those dependencies are defined as transients and the components would be serialized and deserialized, who/ where/ what would be in charge of re-injecting the dependencies? Take a look at http://opensource.atlassian.com/projects/spring/browse/SPR-2896. The toy aspect I have defined before won't take care of dependency injecting upon deserialization, but it's a matter of advicing readResolve too as have been done for the spring 2.0.3 AnnotationBeanConfigurerAspect; it's pretty easy, I'll post the updated aspect later. Cool. It would also be cool if this would work with Terracotta somehow, but I guess that's a bit out of scope for this particular thread. What do you have in mind with this Carlos?

Re: [Wicket-user] Spring integration using AspectJ
Well, to be precise, there is this minor complication of redefining the advice to configure the bean before constructor execution. And you can take advantage of spring-annotations to avoid cluttering your xml app context (that's if you are reluctant to autowiring). What I can do is to update the example project so anyone who is interested could use it as reference. And after that I will take a time to learn what wicket is about :). That'll be nice, thanks for the effort. Eelco - Take Surveys. Earn Cash.

Hi Guys,
Thanks for all your Wicket work.

RenderedDynamicImageResource objects in a GridView no longer works

Is anything amiss? I can't get to the root of the cause.

Re: [Wicket-user] How to catch the error in custome error page?
* tooy li(Gmail):
I want to create a custom page to catch all error , log these
into db and only show some clear infomation into user. i know
set something in the application, but how can i catch these
error in my page?
So you want to handle the exception yourself? Try this in your
Application:
@Override
protected IRequestCycleProcessor newRequestCycleProcessor() {
return new WebRequestCycleProcessor() {
@Override
protected Page onRuntimeException(Page page, RuntimeException
e) {
logErrorInDataBase(e);
return new MyExceptionPage();
}
};
}
You don't indicate which version of Wicket you're using, I assume
the latest in this code snippet.

Re: [Wicket-user] How to catch the error in custome error page?
Yes. For others who don't want to log the exception, you can show
error pages for different categories of exceptions by setting these
methods on ApplicationSettings:
- getAccessDeniedPage()
- getInternalErrorPage()
- getPageExpiredPage()
Unfortunately, you don't get the exception object there.
Perhaps in some near-future version, we can have an error
page factory. I think that would be good because then you
don't need to get involved in the guts of Wicket to do something
pretty simple. How about this:
public interface IErrorPageFactory
{
Page newAccessDeniedPage(AuthorizationException e);
Page newPageExpiredPage(PageExpiredException e);
Page newExceptionErrorPage(RuntimeException e);
Page newInternalErrorPage(RuntimeException e);
}
then make a default implementation so people can override just the
pages they want to customize:
public class AbstractErrorPageFactory implements IErrorPageFactory { ...
}
This would give users the ability to customize without the need to know
details like what's in
AbstractRequestCycleProcessor.respond(RuntimeException e, RequestCycle
requestCycle)
most of which really is necessary to do handle exceptions right.
Maybe some developer on the core team would like to handle this?
If so, we could remove a number of annoyingly non-general settings
from ApplicationSettings in favor of just getErrorPageFactory()

Re: [Wicket-user] Problem with ajax tree and listView
Sorry, don't know why my message didn't send, probably because gmail and
attachement.
I've made a quick start files for the problem. The problem is
If using a ListView to display the tree node value, after I collapse the
node,
I can never expand it again, and the ListItem becomes null. No problem
with a Label.
Could you give me some directions ? Thanks.
Sincerely,
Isaac

Hi,
This is my first time asking questions here.
Hope I can make my question clear.
I'v tried to extend the ajax tree in the wicket extension. The only
modification I made is the output value, which is a customized panel
instead of a label. Following are my html and source.
MyTree.html :
span wicket:id=indent/spana wicket:id=linkspan
wicket:id=image//a
a wicket:id=nodeLinkspan class=icon
wicket:id=icon/spanspan wicket:id=myPanel /
To simplify the problem, I strip most markups of MyPanel.html to
what I think causing the problem.
MyPanel.html :
span wicket:id=outputListspan
wicket:id=outputNamename/span/span
MyPanel.java :
public MyPanel extends Panel
{
public MyPanel(String id)
{
super(id);
ArrayListString list = new ArrayListString();
list.add(name1);
add(new ListView(outputList, list)
{
public void populateItem(final ListItem item)
{
final String name = (String) item.getModelObject();
item.add(new Label(outputName, name));
}
});
}
}
The problem is while I click the junction link,
ListView.renderItem() throws a NullPointerException. After some digging,
I found that the ListItem is null. Then I use getList(), and it
successfully return the list I passed in and the values in that list are
also correct, however the ListItem is null which I don't know why.
Thanks for reading my question. I will appreciate any suggestions.
