Re: Dynamic resources and ajax calls
Hello, thanks for the response, what do you mean exactly by delegate to the mounted resource? I'm thinking I can mount the images resource, and simply reference them using their URI (is this what you mean by delating the call to the mounted resource?), so even if users replace the panel, image loading won't be cancelled, since it will still be waiting for an existing resource (instead of the problem I'm having now, where the resource vanishes before being transfered to the user). I believe this should avoid 3. in your response, what do you think?

Re: AbstractDefaultAjaxBehavior and getCallbackScript
Thank you Martin, we ended up doing the ajax call in a semi-manual way: we are still using PackageTextTemplate but this time we are only passing the AjaxRequestAttributes and declaring them as an object in js, that way we can add extra paremeters that are dynamically generated right from javascript.

You can add: - extra parameters - their values are know when the callback script is being generated - dynamic extra parameters - their values are dynamically calculated just before the Ajax call is done But as you may see at other places you can also use the JavaScript APIs to make a call to the server ad-hoc.

Re: Syncing files with designers
Thanks again for the response. For the first part I had it already
figured out, but having a concrete example is always helpful.
We thought the same - but this not manageable with more than 50 files
in one folder. So we decide to use folders - as already mentioned.
Perhaps I'll write a tutorial...
How did you manage relative links in markup? With css resources it won't
be a problem, the designers can add their resources using link
href=../css/style.css/link and any relative url in it will
translate to the right path, however this is not true for relative paths
inside the html document: img src=../img/img.png / for example, will
be a problem since wicket always resolves relatives paths from the web
root (or webapp folder).
Do you include the resources you need inside all of your folders so
relative paths resolve correctly outside and inside the wicket application?
Thanks in advance,
Edgar Merino

Hello Edgar,
I think I'm missing something: since every WebPage in wicket has
straight access to resources located in the web root (that is, every
path reference in the page's markup is relative to the web root)
Wicket is able to locate resources outside of the web application:
This could be done by implementing an own IResourceFinder:
public final class FileSystemResourceFinder implements IResourceFinder {
private final Resource resource;
public FileSystemResourceFinder(Resource resource) {
this.resource = resource;
}
@Override
public IResourceStream find(Class? clazz, String pathname) {
try {
final File file = new File(resource.getFile(), pathname);
if (file.exists()) {
return new FileResourceStream(file);
}
} catch (final IOException e) {
// ignore, file couldn't be found
}
return null;
}
}
At least you've to add the resource finder to the resource finders
list with getResourceSettings().setResourceFinders(resourceFinderList)
in your applications init method. Alternatively, implement a custom
ResourceStreamLocator. At first the Locator should use the
FileSystemResourceFinder - if there's no match the locator should
fallback to wicket's default resource finder. So far, your application
is able to locate resources from the local file system.
I would like to avoid using folders to organise html files so the
designers can put all the resources they need in their root folder.
The mechanism you describe, seems to use folders, how are you managing
this for the designers?

resources outside of the web application (Think about a complete
physical separation).
We've made a good experience to break-off with wicket's given
package structure - wicket’s resource localization does not fit with
a separation of the responsibilities: the web designer has no
knowledge about the internal package structure and it's not
resistant against refactoring. Therefore, we use a more technical
mechanism based on style, variation locale and the filename.
1. prefix/style/variation/locale/filename.extension
2. prefix/style/variation/filename.extension
3. prefix/style/filename.extension
4. prefix/filename.extension
5. filename.extension

Re: Syncing files with designers
Hello Jan, that seems like a good approach. However, I think I'm missing something: since every WebPage in wicket has straight access to resources located in the web root (that is, every path reference in the page's markup is relative to the web root), I would like to avoid using folders to organize html files so the designers can put all the resources they need in their root folder. The mechanism you describe, seems to use folders, how are you managing this for the designers? Edgar Merino On 04/12/12 04:15, Jan Riehn wrote: Hello Edgar, Yes, this is how it works.

can retro-fit the logic into a wicket page cleanly, without too much

I can't be as flexible as far as throwing in a new row while looping and
outputting table cells.

Static injection not working (wicket-guice)

I've tried ((GuiceInjectorHolder) (RequestCycle.get().getApplication().getMetaData(GuiceInjectorHolder.INJECTOR_KEY))).getInjector().injectMembers(this); however that gives me serialization problems, since wicket is not creating a proxy for my service.

Salve and Guice
I've been searching for information on how to use guice to lookup dependencies with salve, the wiki only mentions how to add the guice locator but I believe that is not working (at least not by it self). I've got a class in a wicket application that is not a component, but I need a service injected, so I'm using salve for this, instead of using @Inject to inject the service I use @Dependency, but I'm getting nullpointerexceptions, any hint?

Re: Salve and Guice
As far as I know, salve will only modify bytecode, it should do that
only once, after the JIT compiler comes in there should be no more
overhead. Correct me if I'm wrong, regards.

Re: Domain Model as interfaces
hello daniel,
well yeah, maybe that can work, but still I'll have to override
every method in the base class in order to add annotations:
...
@Id
@GeneratedStrategy(..)
public Integer getId() {
return super.getId();
}
...
same thing for every getter/setter methods of the entity. I would
like to be able to switch easily between persistence providers because
right now I'm using hibernate but would like to change the provider to
db4o when I've got the time to do so, also this is a project I intend to
release so anyone can add the persistence provider they need easily.

Daniel Frisk escribió:
Hi,
I'm not sure I understand exactly what is your problem but wouldn't
something like this:
Db4oImpl / JpaImpl / WhateverImpl ---extends---
AbstractBaseClassWithYourBusinessLogic ---implements--- YourInterface
Where needed you would delegate to the base class (just adding the
impl specific annotation). Just out of interest: do you really need to
be able to easily switch between different persistence providers?

however I've been thinking and the main problem here lies with db4o,
since it cannot make use of JPA annotations on entities (domain
models). I would like to get rid of those interfaces and use concrete
implementations to handle business code inside the entities, but then
the above problem arises. So what recommendations can you give to
have a fully implemented domain model (using jpa annotations) but
still be able to use any dbms (or orm/dmbs) without having to map
those the domain model at the service layer? I hope I can get some
feedback on this, as it has been the main problem I've been facing

More guice serialization problems
Hello once again, wicket-guice integration has been working good for me, but I needed to get some injected services in classes that were not Components, so I did: Injector injector = ( (GuiceInjectorHolder) RequestCycle.get().getApplication().getMetaData(GuiceInjectorHolder.INJECTOR_KEY)).getInjector(); injector.injectMembers(this); This arises serialization problems with the Guice injector, although I'm not keeping a reference to the injector... this should be because the actual injected service is not handled by a wicket ioc proxy. Igor suggested salve, I've been doing some reading about it but haven't try it yet, but wouldn't it just throw the same exception when using salve since it's not a proxy either? or maybe this won't happen because salve would inject a local dependency (inside a method) when needed? can anyone clarify this for me (and maybe many others with the same doubt)?

Re: GuiceInjectorHolder inside WebApplication
This is happening when using a WebPage, but I'm not using an injector
there... I have a class that receives a service as a parameter, that
service is being fetch by the guice injector and passed to the component
in the WebApplication:
public class MyApp extends WebApplication {
private Injector injector;
...
public ListWidget getWidgets() {
ListWidget widgets = new ArrayListWidget();
//the service needs some resources injected, so is handled by the
injector
Service service = injector.getInstance(Service.class);
widgets.add(new Widget(service));
...
return widgets;
}
}
class Widget {
private Service service;
Widget(Service service) {
this.service = service;
}
public Panel getPanel() {
return SomePanel(service);
}
}
The above is similar to what I'm doing in my real application, below is
the stack trace. Any help is greatly appreciated.

Re: GuiceInjectorHolder inside WebApplication
Ok, using wicket-guice now, problem solved... I didn't want to depend on
guice inside my wicket components, but integration is perfect, so I
guess I'll just leave it like that, thank you Igor.

right. you are not keeping a reference to the injector itself, but you are

i suggest using wicket-guice, it has provisions to make serialization work
seamlessly when you pass instances of guice services into components/pages,
even if they are not serializable.
you can read the spring page on our wiki which explains serialization
issues. wicket-guice uses an identical way of fixing this as the spring
integration.

Guice: injection outside Component
Hello again,
using guice's @Inject inside any component works perfect, however
I've got some objects (not components) that reside inside a component
and need an injected service, since wicket-guice handles only injection
inside components, I'm getting null services:
public class Instantiator {
@Inject Service service;
public Panel getPanel(String id) {
Author author = service.findAuthor(me);
return new SomePanel(id, author);
}
}
I need to fetch the Author outside the panel, the panel is not able to
fetch it. One approach might be to get the service from the Application,
but I do not want to do this since I don't want the application to know
about my Instantiator class, is there a better approach to accomplish
what I need? thanks in advance.

Domain Model as interfaces
Hello, I couldn't find any other place to post this, so I'm doing it here, (it's related to java web development anyway). I've been working on a project where wicket has access to the domain layer through interfaces because I didn't want my project to depend on any dbms, however I've been thinking and the main problem here lies with db4o, since it cannot make use of JPA annotations on entities (domain models). I would like to get rid of those interfaces and use concrete implementations to handle business code inside the entities, but then the above problem arises. So what recommendations can you give to have a fully implemented domain model (using jpa annotations) but still be able to use any dbms (or orm/dmbs) without having to map those the domain model at the service layer? I hope I can get some feedback on this, as it has been the main problem I've been facing when coding scalable web applications.

Reusable DateColumn component
Hello, a few days ago someone requested some advice on how to format the
date within an IColumn, I suggested DateColumn that depended on his
code, but I've been having this necessity in several ocassions too, so
I've come up with a true reusable DateColumn component that inherits
from PropertyColumn, so using it is as simple as:
(DateColumn class shown below)
ListIColumn cols = new ArrayListIColumn();
cols.add(new DateColumn(new Model(header title), propertyExpression));
No extra code needed, regards.

Re: DefaultDataTable with date column
Or simply use an AbstractColumn for that, you can even create a reusable
DateColumn:
public class DateColumn extends AbstractColumn {
private String datePattern; //you can have a Pattern instead
//You can overload the constructor, to have default date patterns
for example
public DateColumn(IModel columnName, String datePattern) {
super(columnName);
this.datePattern = datePattern;
}
public void populateItem(Item cellItem, String componentId, IModel
model) {
Document doc = (Document) model.getModelObject();
SimpleDateFormat df = (SimpleDateFormat) DateFormat.getInstance();
df.applyPattern(datePattern);
cellItem.add(new Label(componentId,
df.format(doc.getDeliveryDate(;
}
}
Then just use this class as you would with any other column, along with
a pattern to apply to the format:
ListIColumn columns = new ArrayListIColumn();
columns.add(new DateColumn(new Model(Delivery date), dd MMM '@'
hh:mm a));

Edgar Merino

Set it to 10 hours, then nobody will get a PageExpired in a normal use Edgar Merino a écrit : Hello, I've got a Panel that contains some AjaxLinks, when clicked they should refresh the data in a DataView, but if the Session expires, I get a PageExpired exception, is there any way to avoid this without adding a TimerBehavior to poll the server every N minutes? (an example of this can be seeing by going to the wicket examples page in the linkomatic application, after the session expires you can no longer click the ajax link counter without receiving a PageExpired exception). Thanks in advance.

Re: Create permanent sessions (or the like)
Thank you again, no sensitive information is to be used. Edgar Merino Piller Sébastien escribió: afaik, there isn't much... if your manage normal data, no problem. But with financial, banking, etc. when you have to manage cash, or sensible data, I'd discourage you to do so... if a user forget to logout or to close his browser and go out, then anybody can continue his session. There is probably some others potential issues, but you'll have to ask other ;) Edgar Merino a écrit : Would do, I think there are not many security implications in doing this, am I correct?
