ModalWindow to ModalDialog // closedCallback

[Korbinian Bachl]

Hi,

when I try to migrate a ModalWindow to ModalDialog i came accross this:

 add(new AjaxLink("edit") {
@Override
public void onClick(AjaxRequestTarget target) {
getModalWindow().setModel(ReferenceEditorPanel.this.getModel());
getModalWindow().setWindowClosedCallback(new 
ModalWindow.WindowClosedCallback() {
public void onClose(AjaxRequestTarget target) {
target.add(ReferenceEditorPanel.this);
ReferenceEditorPanel.this.onUpdate(target);
}
});
getModalWindow().show(target);
}
});

-> What would a correct way be for the setWindowClosedCallback? Have only see 
some onOk(AjaxRequestTarget) and onCancel(AjaxRequestTarget)?

Re: Wicket 10 Release Plans

[Korbinian Bachl]

+1 for M2 or maybe even a RC1 if no big changes are outstanding?

Usually I dont care for latest wicket versions (we stayed on 6 way too long 
:D), 
but since the JavaEE -> JakartaEE this is a showstopper for us as you even 
cant access anything HTTPSession related as you include the jakarta-api on 
jakarta.* 
namespace but wicket 9 only delivers javax.* results

Or if this really takes a year to release maybe a wicket-9-jakarta version?

Re: Wicket 10 Release Plans

Hi Fellow Wicket-Devs!

I'd like to also ask this question as wicket is the only part that holds us 
back from jumping up to JakartaEE (currently JavaEE 8). 

Any eta on final release?

Re: migration from wicket 8 to 9 -> PageManagerProvider

[Korbinian Bachl]

Hi Sven,

thanks a lot!

I've looked into that GaePageManagerProvider and adapted it myself. However, 
during test I somehow observed that the reason why I did use the HTTPSession 
store some long time ago (wicket 1.5/6?) doesn't seem to be existing anymore. 
Reason was that the underlying storage of our prod server has the typical small 
cloud latency. Now with wicket 9 all doing async I didnt see any benefit after 
all with having or not having the custom provider. I even suspect the 
HTTPSession solution to be a tad slower (1 to 10ms) from observation, but cant 
really pinpoint it down.

Its really nice to see how good wicket got here so that speed is quite well 
without the need for custom optimisation.

If you have any idea how to even speed things more up I'm always happy to hear 
;)

Best,

migration from wicket 8 to 9 -> PageManagerProvider

[Korbinian Bachl]

Hi,

Im currently migrating our applications from wicket 8 to wicket 9.6 and so far 
it was a real breeze. I'm very impressed!

One thing however that puzzles me is the following code I had in the 
application init();


setPageManagerProvider(new DefaultPageManagerProvider(this) {
protected IDataStore newDataStore() {
return new HttpSessionDataStore(getPageManagerContext(),
new MemorySizeEvictionStrategy(Bytes.megabytes(24)));
}
});
getStoreSettings().setInmemoryCacheSize(0);



I honestly dont know from when this originated but I had to disable it as it 
doesnt seem to exist anymore accorting to the migration guide.

So I just let de default settings now apply. The original solution was aimed at 
maximum page delivery speed and didnt care much about RAM as we got plenty of 
it. Any idea if I should let the default or can I squeeze out some milliseconds 
by going pure in memory again?

Wicket 8 + 9 on jdk17?

[Korbinian Bachl]

Hi,

has anyone any details about using of wicket 8.x or 9.x under jdk 17?
We currently just migrated from jdk8 to jdk11 as runtime in production and 
wicket 8.x was fine under all things (still had some problems with third party 
libs however). 
Next we want to go to wicket 9.x but since there are some nice bits added to 
the track from 11 to 17 I wonder if anyone has some experience with higher 
version of java and wicket 8 or 9 running under it...

Re: RedirectRequestHandler and HttpHeader?

[Korbinian Bachl]

Hi Martin,

I digged through the past and I now went to make a custom 
Redirect301ToUrlException class that handles it the way I need. 

The problem for me is that wicket has various ways to do a 301 and sometimes it 
sends Cache headers, sometimes it doesnt. 
(e.g.: throw new RedirectToUrlException -> it has no Cache headers, 
getRequestCycle().scheduleRequestHandlerAfterCurrent(new RedirectRequestHandler 
-> it has Cache haders for "no-cache" )
Now, 301 had the idea for "permanent" but in reality, what is now permanent 
isn't permanent in some future time... and now deleted/not anymore existing 
URLs might go back into service. 


An uncached 301 or a short cached one helps to solve problems that arise when 
you delete a resource and let it then point to a new resource just to have the 
original resouce to be resurrected some time later when someone finds out that 
his deletion wasnt a bright idea ;)

Thats also the reason browsers nowadays dont handle 301s that strict way they 
did some years ago. 
Domains get sold, content changes and once 301-URLs get 201s. If you put too 
long a cache on it you face real problems. 
(and I dont mention now the SEO guys :X)


Thanks for your help!

Best,

Re: RedirectRequestHandler and HttpHeader?

[Korbinian Bachl]

Hi Jon, 
Hi Martin,

thanks for pointing me there. It would work that way:

getRequestCycle().scheduleRequestHandlerAfterCurrent((requestCycle -> {
WebResponse response = (WebResponse) 
requestCycle.getResponse();
response.setHeader("test", "1");
response.setHeader("Location", targetUrl);
response.setStatus(301);
// response.sendRedirect(targetUrl); -> is only 302!
}));


the sendRedirect ist always 302, 301 only works with the location header. Feels 
bit "un"wicket to do all this. 
The main goal is to just redirect with 301 to an URL and have some headers set 
- is there any easier/ faster way to do this?

In times before wicket 8 I had a custom RedirectTarget301 extends 
RedirectRequestTarget for this.

I've seen the RedirectToUrlException in wicket 8 but that basically just wraps 
the above logic into a super(new RedirectRequestHandler()) of 
ReplaceHandlerException.

Would that be the best way to have this solved? A custom 
Redirect301ToUrlException(String targetUrl, Headers... header) ?

Re: best way to get wysiwyg with wicket

[Korbinian Bachl]

Hello Maxim,

thank you for the list. However, beside that tinymce3 + 4 are quite outdated 
isn't there anything non html-wysiwyg existing so far? 
My problem is that, after we use tinymce in another part of the project we made 
the experience that letting non-tech people write HTML (even in WYSIWYG) mode 
just doesnt work. They end up copy n pasting from all over the web and 
inserting things they neither see nor understand - thats why we need some 
simplification like markdown (e.g.: https://ui.toast.com/) or even pure 
block-based editors (https://editorjs.io/)...

I've stumbled over toast UI (https://ui.toast.com/), but I'm not sure if wicket 
would be able to execute some kind of JS function (editor.getMarkdown()) on 
before sending the form and catching it into a model...? 

Best,

Hi,

I need to be able to let complete novices edit and write nicely formatted texts 
in an backend thats powered by wicket (required e.g.: H1-H4, normal text, bold 
text, images - only simple stuff mostly).
In the past I used the ckeditor but that outputs html and Im not sure that 
cluttering font sizes and stuff like that into anything that needs later be to 
transformed to be used on either desktop or mobile in the year 2020 is still as 
sufficent as it was 10 years ago. So I stumbled over markdown that might be a 
way to avoid this, but not sure If I missed somthing better?

Beside, has any of you an idea where to look at to put this together with 
wicket, especially as I need to be able to have them insert images from some 
gallery picker that gets its image-resources from some kind of dataprovider.

Any idea or solution is greatly appreciated. I know this is not pure wicket 
related stuff but I hope its still ok to ask here.

Hi Sven,

yes, I am sure. I can give you the url to an example live app if you like. 
Wicket logs this error at the console level, yet the browser detects no error 
in execution at all... 

I mean if you look at the code below, you see the reference error to the 
etCommerce variable, but i got an if(etCommerce) check beforehand?

Wicket.Ajax.Call.processEvaluation // how to not get reference errors in case one has to check for a var?

[Korbinian Bachl]

Hi,

i've added some JS to be exectued after AJAX but wicket always sees an error 
where none is:

Wicket.Ajax:  Wicket.Ajax.Call.processEvaluation: Exception evaluating 
javascript: ReferenceError: etCommerce is not defined, text: (function(){var p= 
{
   ...
}
if(etCommerce) { etCommerce.sendEvent('insertToBasket', product, 1); }})();

Here we get an error that etCommerce is not defined - thats right but it is 
checked for it with "if(etCommerce)", so its perfectly valid JS?

Also if I user if(etCommerce !== 'undefined') nothing changes as well, error 
stays?!?

How can I get rid of these console alarms? And why is this also done in 
production mode?

Re: AttributeModifier values gets escaped

[Korbinian Bachl]

Hi Sven,

im using this in regards to the picture element's and the values then are going 
through JS :/

I coded now around this for the JS part, but it would be nice to have a 
.setNoEscape(boolean ) option on the AttributeModifiert 

Browsers get the ampersand in URLs but JS is a nightmare with it; Funnywise, 
even if I go on the onComponentTag and try to do it there it gets escaped... 
not sure why though;

Best & Thanks for the feedback!

AttributeModifier values gets escaped

[Korbinian Bachl]

Hi,

I try to manipulate some tags on an WebMarkupContainer called image. If I do:

image.add(AttributeModifier.replace("src", imgUrl + "?a=1b=2"));

the src is not as expected: "...?a=1b=2" 
but its escaped as "...?a=1amp;b=2"

I tried setEscapeModelStrings false on the image itself, wont work and 
AttributeModifier has no way to escape

Any idea what to do now?

Re: multiple AjaxFileDropBehaviour on single page

[Korbinian Bachl]

Hi Sven,

so to get this right: all wicket ajax is basically a queue where only 1 
instance is worked on at a time and nothing is possible in parallel? 
(but browsers and ajax in parallel is working since at least 2011? e.g.: 
jQuery.when() )

You mention the upload to a resource - how would this change it in that in 
could be parallel and could you point me an example?

multiple AjaxFileDropBehaviour on single page

[Korbinian Bachl]

Hi,

wicket 8 has this neat AjaxFileDropBehaviour and it works like charm. However, 
if I have multiple components on one page with a AjaxFileDropBehaviour each and 
the upload of 1 drop is running, i cant upload a 2nd one at the same time; Any 
idea how to solve this? 

E.g.: File 1 with 100MB gets dropped onto component A, File B wiht 50MB gets 
dropped onto Component B about 10 secs later - upload of a is not working and 
page somehow goes stale. It might be noteworthy that during the upload an 
IAjaxIndicatorAware spinner is shown on Component A (and expected on B);

Re: Demo Page with User Related Data

[Korbinian Bachl]

Hi,

in case of a regular session you can use a HttpSessionListener and use the 
public void sessionDestroyed(HttpSessionEvent event), similar to that one here:
https://stackoverflow.com/questions/7756054/how-to-call-a-method-before-the-session-object-is-destroyed
(wicket is still a java framework, meaning all underlying java web things 
usually just work)

Also AFAIK the page should not get detached as long as the page is still 
active, meaning it has AJAX panels on it that are still doing things, maybe 
MartinG can shed some light on this;

As far as I understood all pages go after creation und usage to the page store 
and get removed from that depending on the configuration?

Re: Demo Page with User Related Data

[Korbinian Bachl]

Hi,

take a look at 
https://ci.apache.org/projects/wicket/guide/8.x/single.html#_components_lifecycle

You might want to move the code from constructor to 
onInitialize()
and you can use 
onRemove()
to free it up as this is called when the component gets removed from the page / 
the page itself gets removed;
Keep in mind that wicket stores old pages by default. In your case you might 
also want to have a look at LoadableDetachableModel, so that the model can 
react with "activation"/"passivation" of its data;

The goal should usually be to not store any data at all that can be retrieved, 
so to not waste memory - said, it might be necessary in your case to store it 
with the page as it might be very expensive to (re)create the data, then the 
above onInitialize/ onRemove on the page level would be good to use;

Best,

KB

Re: ListenerRequestHandler / urls from the past... - component not found

[Korbinian Bachl]

Yeah - no;

the problem is here the amount of pages and the crawl-budget of a crawler per 
domain; 
If you waste 1000's of urls you get not indexed well enough and even penalized; 
I know this and we use canonical all over the places, but seo guys clearly 
showed that we need to get rid of this and if we cant we have at least to put 
it into a named parameter;

Beside, when I look into google webmaster myself I can clearly see these many 
component/ parameter combos make a real pain, so we need to get rid of these. 
While all our pages are already stateless we still have these in terms of AJAX 
and Forms.

Re: ListenerRequestHandler / urls from the past... - component not found

[Korbinian Bachl]

Hi Sven,

well, the problem here are our clever webbots - especially bing and even worse 
google :)

See, bingbot or googlebot index now e.g.: 
(derived from wicket examples)

www.domain.com/choice

and a load of bullshit like 

choice?2-1.IBehaviorListener.0-form-makes
choice?2-1.IBehaviorListener.0-form-go
[add here sometimes 100's of further ajax links]

that now lead to having indexed many many pages that nearly cant be taimed; 
Even using robots.txt or their webmastertools makes this a nightmare as the 
potential namings you can manually fix are in the hundreds or thousands;

If all wicket things would be behind an parameter e.g: 
?wicketHandling=2-1.IBehaviorListener.0-form-makes
?wicketHandling=2-1.IBehaviorListener.0-form-go

you could just concentrate on that parameter and save literally many many hours 
of work and seo complaints :)

IMHO this was standard up to wicket 1.4 in a way that all those page and 
component info was put to a certain wicket interface root path e.g: 
?wicket:interface=:0 and that allowed much easier taming of these problems 
than its currently for me;

Re: ListenerRequestHandler / urls from the past... - component not found

[Korbinian Bachl]

Thanks for the answer - that gives me the right direction. Say, do you know if 
it would be possible to have the wicket component part not in the url like 
currently but using a named parameter? e.g.:

http://examples7x.wicket.apache.org/forminput/?0-1.IFormSubmitListener-inputForm

should instead be 

http://examples7x.wicket.apache.org/forminput/?wicketHandling=0-1.IFormSubmitListener-inputForm

where wicketHandling would be the global named paramter where the wicket puts 
all its infos into that parameter and not just add it to the url?

ListenerRequestHandler / urls from the past... - component not found

[Korbinian Bachl]

Hi,

I've got some problems with 404/ 500 error codes in my wicket app that happen 
to come from the past... Now, when wicket makes any url for a component this 
one gets added to the path, e.g.: 
http://examples7x.wicket.apache.org/forminput/?0-1.IFormSubmitListener-inputForm

So when time goes by and the component name changes to e.g.: inputForm3 and one 
then calls the above URL wicket annoys with an 500 error... 
(attention: it is also related to the fact if there is an active session or 
there is not! - happy debugging !)

reason: 

org.apache.wicket.core.request.handler.ComponentNotFoundException: Component 
'brix-tile-24:form' has been removed from page.
at 
org.apache.wicket.core.request.handler.ListenerRequestHandler.respond(ListenerRequestHandler.java:166)
at 
org.apache.wicket.request.cycle.RequestCycle$HandlerExecutor.respond(RequestCycle.java:912)

(error from my app - u get a bit different one from the wicket examples app if 
you manually change the component info part - sometimes just an 404, sometimes 
500)


So, how can this be fixed that instead of giving us this 500er error in live 
systems that wicket should just ignore the problem? I mean failing in dev is OK 
but in deploy? So basically wicket shall treat it as 

http://examples7x.wicket.apache.org/forminput/

request;


IMHO the problem here is in ListenerRequestHandler at 164:

if ((component == null && !freshPage) || (component != null && 
component.getPage() != page))
{
throw new ComponentNotFoundException("Component '" + 
getComponentPath()
+ "' has been removed from page.");
}

so we know there is no component and then wicket goes berserk and throws it... 
Problem arises with many URLs indexed anywhere on the web and pointing to ones 
page as well as bookmarked pages from users - they have the old component info 
in the paths and there is no way to remove that!

Re: wicket 8 / RootRequestMapper vs CompoundRequestMapper

[Korbinian Bachl]

Awesome! - I think I now got this. 

So, i need to use 
IRequestHandler mapRequest(Request request);
to handle the incoming request to "decode" the fake path/ part
and using 
Url mapHandler(IRequestHandler requestHandler);
I can put in any fake path/ part into the URL that goes to the outside.

Thanks a lot Martin! That saves me from doing any JCR/ Brix related hacking as 
I can now internally map the pages/ paths as I need it :)

Re: wicket 8 / RootRequestMapper vs CompoundRequestMapper

[Korbinian Bachl]

Hi,

thanks a lot for the clarification. So say I want to do some kind of path 
rewriting/ faking like the apache mod_rewrite does. I then would use a new root 
mapper and have this one handle the request, fake the url and give it to the 
"prior" mappers to resolve as in that case I need to make sure I'm the first 
one in the hierarchy. But where would I then rewrite the generated URLs?

wicket 8 / RootRequestMapper vs CompoundRequestMapper

[Korbinian Bachl]

Hi,

situation: I need to add some "special" URL handling for certain URLs to have 
product pages and catalog pages on root. As we also use brix we already have at 
least one compoundRequestMapper already in use. 
Now, wicket seems to have 2 places for that. A new RootRequestMapper e.g.:

YourApplication#init():
old = application.getRootRequestMapper()
application.setRootRequestMapper(new CustomRequestMapper(old))

or a CompoundRequestMapper e.g.:

application.getRootRequestMapperAsCompound().add(new CustomRequestMapper(old));

But what are the pros or cons of using either RootRequestMapper vs 
CompoundRequestMapper?

>>

It may sound a bit awkward but the situation is like this:

Page with componentes A, B, C, D on it
Component A is just an resolver that fills a request scoped CDI with decoded 
data for components B,C,D in its constructor
Component B,C,D now reacts onto these data from Component A in the 
onBeforeRender method

all is fine if its not rerendered like it was used some years now (code stems 
from looong time ago :/ )

now I introduced an form into component D and there the mess began as A's 
construtor didnt get called again as its page was already rendered... 

this was all made before wicket had the current lifecycle as well as the 
methods that get invoked we have today in wicket 7 and 8;

Ah ok,

So is it correct if I assume that onConfigure gets called in the same order as 
the components get added to the page and in that order on each re-render?

What would be the best way in 2018 to have decoupled components that share 
logic?

wicket component lifecycle after form submit

[Korbinian Bachl]

Hi,

from 
https://ci.apache.org/projects/wicket/guide/8.x/single.html#_lifecycle_stages_of_a_component
 and 
https://ci.apache.org/projects/wicket/guide/6.x/guide/componentLifecycle.html I 
see how the lifecycle of a wicket component is intended to be.

But how does it go for the lifecycle of a component on a page where the page 
gets submitted by a form in another component?

I know that the page tree wont get recreated completely after the onSubmit, but 
I wonder if there is any method that is guaranteed to be called on each 
re-render phase as I somehow struggle with parallel CDI work done in a 
@RequestScoped bean 
(this is re-created completely when the submit is called as it is a new http 
request) 
and some things in onBeforeRender wont even get called - or can it be that this 
is because the "hasBeenRendered" is true for rerenders by form submits?

Sorry if the question is dumb but I somehow locked myself in by doing too much 
in different onBeforeRender methods all over the place..  (that is also mainly 
because most of that code stems from wicket 1.3/1.4 era);

Is there a method that gets executed every rerender after the page has been 
constructed - similar to onConfigure ?

Re: make all links to absolute ones?

[Korbinian Bachl]

Thanks a lot Martin!


I now did an quick override of it and now all URLs are absolute like I wanted 
them to be... Is there a special reason why wicket is so into this relative 
nightmare? I mean, why not just make all either absolute or full-URLs? 

I mean depending on the Url paths you get so great things like (same jquery, 
different wicket pages):

make all links to absolute ones?

[Korbinian Bachl]

Hi,

in wicket 8 (M9) in RequestCylce there is

protected UrlRenderer newUrlRenderer()
{
// All URLs will be rendered relative to current request (can 
be overridden afterwards)
return new UrlRenderer(getRequest());
}

but how can I override it with a custom UrlRenderer? - I try to make all URLs 
to absolute ones and I tried to just override the shouldRenderAsFull with true 
in UrlRenderer but I cant seem to find how to make wicket use the new 
UrlRenderer. The only part where this is used is in ServletWebResponse as well 
as RequestCycle, however, RequestCycle itself is used only on 
Application.internalInit and the warnings there to not touch it are strong :/

Any Idea how I can override this part globally?

manual resolving of path

[Korbinian Bachl]

Hi,

where would I need to look at if I wanted to resolve the path from the root of 
the webapplication inside a wicket application root?


e.g.: domain.com <- has wicket app on ROOT deployed
domain.com/foo <- path mapped to foo-webpage
domain.com/foo/bar <- I now want to get the request not resolved by foo-webpage 
but by my own custom resolver-webpage but I cant map this as usual as the 
mapping comes from a DB and can change anytime
domain.com/bar2 <- I also want to hijack this one temporary even we have a page 
mounted to /bar2

Any idea how I might "hijack" the request and resolve it to another page?

Re: AjaxFormComponentUpdatingBehavior not triggering ListChoice model update in Firefox in Wicket 7.9.0

[Korbinian Bachl]

Hi Chris,

can it be that you have 2 instances of jQuery in your page? - bootstrap.js 
often comes with embedded jQuery and then you would overwrite the wicket one 
with the bootstrap one, that will lead to problems where you dont get notfied 
at all. I know this from foundation / sites, where you are best using a second 
global variable beside the one from default jQuery.

In this part wicket is a bit of a troublemaker, you could try to replace the 
wicket jQuery with an empty.js resource or even pull in the bootstrap one 
instead (e.g.: bootstrap script file instead of wickets jquery only script), so 
only 1 jQuery gets executed. Also the migrate you use is quite old, I would 
suggest 1.4.1;

wicket 7 / 8.x and relative to absolute path

[Korbinian Bachl]

Hello,

how is it possible to make from an relative page path and absolute one as 
string in wicket 7 or 8?

In wicket 1.4 it was quite a mess where one had to manually build it from 
string and this tended to be quite buggy (and much much code), and I somehow 
hope that it may now be easier in times of wicket 8 and java 8;

The idea is to have a basic funtion e.g:

public static String toAbsolutePath(String relativePagePath) 

where one could enter the relativePagePath, relative to the current URL in the 
browser window;

Best,

Korbinian

Re: wicket 6.x / java.text.ParseException on multiple div's

[Korbinian Bachl]

@Martin Spielmann, @Per Negro

thank you for your help. In fact I found out that there was a glitch in the 
HTML, however, not with the div's! - It seems as the parser has some problems 
when there is an error in the markup with quotations; In my case I had a 
innocent looking 



on the page hirarchy at the divs; (content a much lower level)

If you look at it you see 2 quotations at 340 and this seems to break the 
parser. He gives out the error, but the error is not where he reported it. 
Since my HTML got over 1000 lines i had quite a time to find this little bugger.

Anyway thanks for your help!

Best,

Korbinian

Re: wicket 6.x / java.text.ParseException on multiple div's

[Korbinian Bachl]

Hello Martin,

I tried to look for this but I isn't that easy. He really complains about fine 
closed div's if I remove the mentioned div's it renders fine;

I can trigger the error when I just enter this into my page HTML:


A
B


and thats a perfectly fine HTML

Best,
Korbinian

wicket 6.x / java.text.ParseException on multiple div's

[Korbinian Bachl]

Hello,

I'm still on migrating a big wicket 1.4 app to wicket 6.23, and I now got a 
problem I dont know how to solve. A page throws following error:

java.text.ParseException: Same attribute found twice: div (line 163, column 52)
at 
org.apache.wicket.markup.parser.XmlPullParser.parseTagText(XmlPullParser.java:698)
at 
org.apache.wicket.markup.parser.XmlPullParser.next(XmlPullParser.java:311)


so far I would expect this to happen on wrong/ malformed HTML - but my HTML is 
fine is indeed needed this way!

complained HTML:



      
           content
               
        
        
              content
        


So what is going on here? Why does wicket complain about those poor div's? Is 
there any way I can disable this check for div's??? For me this behaviour seems 
as a bug as div following a div is perfectly fine HTML code?

Re: wicket 6.x / FeedbackPanel StackOverflowError

[Korbinian Bachl]

Thank you Tobias,

I followed your advice and it worked, after looking at 
https://ci.apache.org/projects/wicket/guide/6.x/guide/componentLifecycle.html 
it seems the best way to fix this is e.g.:

@Override
protected void onConfigure() {
if(loginForm.hasError()) {
setVisible(true);
} else {
setVisible(false);
}
}

The lifecycle is a bit off from my wicket 1.3/ 1.4 memories it seems :)

Best,

Korbinian

wicket 6.x / FeedbackPanel StackOverflowError

[Korbinian Bachl]

Hello,

I'm currently migrating a wicket / brix application from wicket 1.4 to wicket 
6.23; So far most seems well, but there is a thing I'm really stuck at. My code 
uses FeedbackPanel regularly like this (on many many pages/ tiles):

loginForm.add(new FeedbackPanel("feedBack") {
private static final long serialVersionUID = -2594094600209896717L;

@Override
public boolean isVisible() {
return loginForm.hasError();
}


}.setEscapeModelStrings(false));

and this worked fine in wicket 1.4; With wicket 6 now if I access a page 
containing this I get

Re: how to add rel=nofollow to all links

[Korbinian]

rel=nofollow will tell to not weight it but google will still go it - a 
way to stop this is by doing a robots.txt

e.g.: 

User-agent: *
disallow: /*?wicket

for wicket 1.4 does the trick, in your case

User-agent: *
disallow: *ILinkListener*

might work - can test this with the google webmaster tools on the specific 
links that harms you

 would make sense to add attribute rel=nofollow to all wicket links? 
 If so is there some way how to do it automatically?

Re: how to prevent the log file was full of exceptions

[Korbinian]

Hi,

exceptions are usually thrown with a reason - and the main reason why you 
get so much in your log is that brix with wicket 6 isnt yet finished. 
Especially the url-sharing part between brix and wicket is quite a problem 
as brix relies on full control of the space while wickt 5 + 6 introduced 
the concept of multiple url handlers - a concept brix itself never cared 
for as it was created against 1.4 once and the traversal to wicket 5 and 
wicket 6 never got finished yed. Especially the introduction of wicket 5 
into brix is full of errors. I started to clear out many of them on the 6 
branch, but hadn't enough time yet. Beside that I wanted to wait till 
wicket 6 is released, as programming against dailies is problematic when 
your low on time.

What brix currently needs is a logic similar to the SSL Url handler in 
wicket 6, where requests go dont the flow while still the brix handler is 
the master of these requests. I've done that on an experimental 
base. 

Best,

Kobinian

 Hi,

 I am looking for some solution how to log all exceptions in my code. I 
 tried to override onException method in RequestCycleListener but log file 
 was full of exceptions like this:

 org.apache.wicket.protocol.http.servlet.ResponseIOException: 
 ClientAbortException:  java.net.SocketException: Broken pipe

 So I am thinking about something like this:

 private static Class[] KNOWN_EXCEPTIONS = 
 {ListenerInvocationNotAllowedException.class, ResponseIOException.class};

 @Override
 public IRequestHandler onException(RequestCycle cycle, Exception ex) {
 HttpServletRequest request = (HttpServletRequest) 
 cycle.getRequest().getContainerRequest();
 if (ex instanceof PageExpiredException) {
 LOG.debug(MessageFormat.format(PageExpiredException for 
 request ''{0}'', request.toString()));
 }else if(isKnownException(ex)){
 LOG.warn(MessageFormat.format(InternalErrorPage for request 
 ''{0}'', Exception message ''{1}'', request.toString(), ex.getMessage()));
 } else {
 LOG.error(MessageFormat.format(InternalErrorPage for request 
 ''{0}'', request.toString()), ex);
 }
 return super.onException(cycle, ex);
 }

 private boolean isKnownException(Exception ex) {
 for (Class? extends Throwable clazz : KNOWN_EXCEPTIONS) {
 if(Exceptions.findCause(ex, clazz) != null){
 return true;
 }
 }
 return false;
 }


 Is this right approach? If yes, another question is how to deal with this

1.6 - 1.6.0_32):


-server
-XX:+UseConcMarkSweepGC
-XX:+CMSPermGenSweepingEnabled
-XX:+CMSClassUnloadingEnabled

Also make sure permGen is specified big enough, e.g:
-XX:MaxPermSize=384m


Also, I wouldn't recommend to restart the tomcat too often, else you'll 
loose the goodies of the HotSpot VM;

Re: Wicket 1.5 and glassfish 3.1.1 clustering (session replication)

[Korbinian Bachl - privat]

Hello,

Vytautas, can you please make a bugreport on
http://java.net/jira/browse/GLASSFISH

3.1.1 indeed has some quirks, but its better than 3.1; HTTP/HTTPS and 
wicket will loose JSessionId

a.t.m. but if we give nice bug reports they will get fixed in 3.1.2 :)

Re: Wicket and Amazon EC2

[Korbinian Bachl - privat]

As long as you're using any EC2 instance with an EBS-AMI its just 
another server you can deploy any operating system on you like.


Only remind that you mustn't terminate the machine but only stop/pause 
it as terminating equals to throwing away the server in reality while 
pausing means to shut it down (not pause it in memory);


So to use wicket on I suggest you to first create an Ubuntu LTS AMI 
following these instructions:

http://www.ubuntu.com/cloud/public/deploy

Then you install java on it using apt-get or aptitude (make sure to 
update indices first) and install the wanted appserver like e.g.: tomcat 
or glassfish and do the startup-scripts, and thats it.


After that I suggest you to clone the EBS drive to a SNAPSHOT, so 
instantly can launch more instances on exact same config (see EC2/EBS doc).


Then you bind any needed elastic-IP's to it and deploy you wicket app - 
thats it :D


In case you run low on power or memory you can adjust the instance type 
to the one you need, but bear in mind that the micro instance only 
provides you 32 BIT while the rest is 64 BIT, so in case you did a 64BIT 
OS you can't go to micro;


thats it :)

This works fine, but as an example I would like to have the url for a single

I mount each wizard as a page, so the url then looks nice. But when step two

The current version there is 2.0.2. From the release notification:

The new version, 2.0.2, should address any issues people have had

wicket:extend and wicket:child tags to get thing working but with no

experience I thought extending should work like jsp:include. When I 
try to get my header into the index page nothing is showing up.


Code of Index.html
html   headtitlesome titlet/title

   head/head
   body
   wicket:extend
   div id=header
   h1Header.html/h1
   /div
   /wicket:extend
   /body
/html

Maybe I'm getting things totally wrong?

Another thing I wonder about is how does wicket know which page to include?

Re: 5 Days of Wicket

Hi Andrew,

first I was a bit curious about another wicket intro(TM) but after 
reading it I was amazed. It is one of the best blog entries for wicket 
starting I've read as it elegantly uses helps like the quickstart and 
then shows how to config it for real world usage.


Only things I miss is:

- as you use Hibernate directly you really should mention databinder 
(databinder.net) somehow, as this spares you much work in that way


- some more words to the image thing, as its IMHO not clear why youre 
doing this for a pastebin-like app


*Thumbs up*,

I would do neither! - you should have a look at JCR, especially Apache 
Jackrabbit as its reference impl. - that'll solve your problems while 
still keeping you flexible in future. You also might want to have a look 
at Brix-CMS as a good starting point and has good reasons to use it:

- it gives you most needed CMS functions for your shop
- it uses JCR to save its content
- it can be extended using Tiles that are somewhat wicket-panels that 
implement a special interface
- its made by 2 wicket core devs that build it as a basement for their 
selling-shopsoftware

- big part of its code is written by Igor :)

Re: [OT] Simple file repository?

[Korbinian Bachl - privat]

Hi Kaspar,

just to save you some pain: in case of Jackrabbit don't use 
TransientRepository but RepositoryImpl instead and make it launch in the 
init() of you app and go down on the onDestroy() (in case you want to 
bundle it with your app).


Transient has some bad behaviour and currently makes problem (1.5.2) 
when shutting it down using the repo.shutdown() as not all resources are 
100% released in case you have still some connections (e.g. over RMI).


Also make sure you safely de-register any exports first, then shutdown 
the repo using repo.shutdown() to prevent any locks. Also don't share 
Session over longer runs or threads as Session is not thread-safe.


To see whats in your jackrabbit repo its best to connect via RMI, so 
you only depend on your real config, not any fancy (especially this also 
saves you from pain by having tools depending on different JR version 
than you are on!). A good way to dig in is using the JCRBRowser (either 
eclipse plugin or standalone) from 
http://sourceforge.net/projects/jcrbrowser .


Also a good tool pool is under: 
http://dev.day.com/microsling/content/blogs/main/jcrtools.html - a JCR 
Tools roundup, bit older (2007) but still worth looking at; Under 
http://wiki.apache.org/jackrabbit/FrontPage you'll also find good info 
(the Jackrabbit page itself and its doc can be best described as 
useless nightmare).


Also a side-start-point might be the DAY CRX Developer edition from 
http://www.day.com/content/day/en/products/crx/download/registration.html 
as this is practically a jackrabbit + tools thing. Its good to start and 
understand the idea and behaviour behind JCR, even the prices are 
Enterprise only you are free to use them for developement purposes only.


Hope this one helps you get started.

Best,

Korbinian

Does anybody know of a simple Java library that satisfies these

For example: a Hibernate database with a relation Files holding 
tuples (DocId, FilePath), and a service with:


- id store(stream): creates from the stream a new file on the file 
system and inserts a new tuple into the relation, returns id
- stream edit(id): returns a stream to a temporary copy of the file 
with the given id; updates the corresponding tuple to point to the 
temp file

- void remove(id): removes the corresponding tuple form the relation

... and a background job which deletes dangling files.
I suggest you something implemented on the top of JackRabbit (Java 
Content Repository). You might have a look at Brix, which is a CMS 
based on Wicket and JackRabbit.

Re: propertycolumn - date column, checkbox column

[Korbinian Bachl - privat]

Hi,

use AbstractColumn instead and provide a panel that does what you want, eg:

columns.add(new AbstractColumnMarke(new ModelString(CHGE), 
changed) {


public void populateItem(ItemICellPopulatorMarke 
cellItem, String componentId, IModelMarke model) {
cellItem.add(new ChangedCellPanel(componentId, 
model.getObject().isChanged()));

}


@Override
public String getCssClass() {
return center w50;
}
});

It is usually always a good idea to have a look at the classes you want 
to customise (here: PropertyColumn that extends AbstractColumn) as most 
parts of wicket utilize extensions of abstract classes and/ or 
implementations of interfaces;


Best

PS: the code is from 1.4-rc2, so using generics - in 1.3 you can't do that

Christoph Grün schrieb:

Hi all,

 


columns.add(new PropertyColumn(new ModelString(Title), title,  title

How can I have such a  property column that displays java.util.dates? 


I would also need the same for checkboxes or true/false values.

 


Thanks a lot,

wicket + spring + jpa/ hibernate = lazy load exception

[Korbinian Bachl - privat]

Hi,

I'm currently struggling with the famous lazy load exception under 
spring + jpa with wicket.


The problem is, in my case, that i pull an entity from the database 
using a spring-bean (@SpringBean) and JPA (hibernate). Then in the 
wicket class i need to walk the entity tree a bit, based on the needs of 
the user (preloading wont work, as i dont know the direction the user 
wants to walk and the whole entity tree is too complex to grab it all at 
once).


If I use the Entity myEntity.getMyOtherConnectedEntity I get the lazy 
load exception (transaction already closed). So I tried to use the 
OpenSessionInViewFilter to solve this, but it just won't work - no 
reason why, as the error stays exactly the same.


Currently I ended up using this:
@PersistenceContext(type = PersistenceContextType.EXTENDED)
private EntityManager em;

However, I'm not sure if this is the way it is supposed to be?
( I read so far that this disables a big part of springs-transaction 
handling support but didnt see any impacts so far)


Has anyone a different aproach/ solution for this using wicket + spring 
with JPA?


Best,

Korbinan

Re: wicket + spring + jpa/ hibernate = lazy load exception

[Korbinian Bachl - privat]

I think it could be something about
 missing usage of loadabledetachable model..?

not for me, as the original entity is pulled using an 
loadabledetachableModel via a SortedDataProvider :/


if you look around, the all called solution for this is the 
OpenSessionInViewFilter and the usage of
bean id=transactionManager 
class=org.springframework.orm.jpa.JpaTransactionManager

for that (latter one is used by me, too)

However, the OpenSessionInViewFilter will not work with wicket, even if 
mapped to /* in the web.xml

you should use DataTable instead of ListView for that; there you can

Re: Wicket Cart: open-source e-commerce wicket app

Hello James,

I'm also quite interested into this, however I'm stuck in work at
moment, so don't have too much time.

2 things you really should consider:

- Brix! the CMS mentioned before, developed by 2 wicket-core devs and 
it would add all content functionality and house the cart, list etc;


- BmeCAT: you *really* want to have a look at the BMECat 2005 
definition; Its just an XML definition format but will show you what 
kind of information and details about products should be stored and at 
what way - just have a look at: http://www.bmecat.org/English/index.asp?


If you got any questions, feel free to ask!

Korbinian

PS: you also could have a look a osCommerce to see how you shouldn't do 
it :P

AFAIK you should add the tinyMCEBehaviour to the Textarea, sth like this:

ta.setConvertEmptyInputStringToNull(false);
TinyMceBehavior tmb = new TinyMceBehavior(getAdvancedSettings());

Re: Dynamically Making changes to Tree Node

[Korbinian Bachl - privat]

He is a core dev - just listen to him :P

ok, simple treeNode would be:

wicket:panel
IM A NODE
div wicket:id=content-/div
/wicket:pane

and Java:

class TreeNode extends Panel {

public TreeNode(String id, AnyOtherPossibleThingsYouNeed o) {

if(IWantADeeperNodeFromHere) {
add(new TreeNode(content));
}
else {
add(TheContenYouWantPanel(content));
}
}

}


as long as your IWantDeeperNodeFromHere is true you get a tree based 
upon this:


IM A NODE
div
IM A NODE
div
IM A NODE
div
   TheContentYouWant
/div
/div
/div

(case of 3 Nodes you get 3 stacked divs - place whatever you like; 
Wicket is all about OO so inheriting itself and recursive calls are no 
problem at all.

Re: [ANN] Brix 1.0 beta1

[Korbinian Bachl - privat]

Jeremy,

please believe me and *don't* use either osCommerce or XTCommerce. Their 
code is just useless, they have no way of easy changing things and every 
release you will need to alter most of your provided code (there is no 
stable plugin system - they plan to do this for long now but havent been 
very successful yet).


The only promising one solution yet is IMHO magentocommerce ( 
http://www.magentocommerce.com/ ) but it suffers a bit from performance 
perspective (but they are just 1.0 - so there will be improvement here).


If you need a basement for some small shops you either want to go 
megantocommerce or maybe look at some rent solutions (even amazon has 
one that is not too bad) - but dont use the 2 osCommerce's (XTCommerce 
is more a fork, but still suffers from many things osCommerce has) - or 
take a look at brix, as you only would need some special tiles that fit 
your needs and could be shared among your shops mostly.


Best,

  I'm curious about your use of it in ecommerce sites.  Several friends of
mine want small shops built for them so that they can sell some things
online.  Until this point, I've just been throwing together instances of
osCommerce [1] for them.  But, then, they need me to change page layouts,
etc.  I've been wishing there was an easy solution that rolled the two
together - give them a storefront, and they can edit their own pages
(without FTP / editing PHP - these are not developers by any stretch).
Something where they could edit page content with a WYSIWYG.

Of course, I could build this with Wicket, but can't afford the time right
now.  And then you have the Wicket / PHP binding which would be a pain, too.

Anyway - is there some open source ecommerce package that you bundle with
the CMS, or is the ecommerce part what your company does, and the CMS is the
open part?

Hi Igor  Company!

nice to see your CMS nearly ready! I already had a quick look at it and 
there is one thing I'm not quite sure about: Is Brix thougt of giving a

to extend a existing wicket-app with the features of a CMS?


I mean I looked the images and read the wiki, and while

new underlying layer in the features under 
http://code.google.com/p/brix-cms/wiki/Features its listed as Easy to 
embed into existing Wicket Web Applicatons  - which puzzles me a bit.


I mean, lets say you 2 things:

1. you want to build a new pet-shop (or cheese-shop in case of Eelco and 
Martinj ;) - would you start by using brix and put the rest on top of it?


2. you already have a pet-shop based on wicket but want to extend it

would this mean some bigger changes to the rest of the pet-shop?

brix is about cms functionality only, it is not a higher-level
wicket application framework.

it embeds in both directions: you can have pure wicket pages living
next to brix-managed cms pages, and you can also have wicket
components living inside brix pages via brix's concept of Tiles.


Sounds very good - can you also have brix-pages living in a 
wicket-page? (some kind of embedded part)





I mean, lets say you 2 things:

1. you want to build a new pet-shop (or cheese-shop in case of Eelco and

does your cheese shop require any cms functionality? 


its a special existing-just-to-ask-such-dumb-questions-one - so yes ;)


if you need an
admin to be able to change markup for your cheese shop pages via a cms
or add new pages to the website via a cms then i would build the
ecommerce part as a set of tiles and drop them into brix pages. this
is, indeed, the primary usecase for brix as my company is using it to
build ecommerce sites.


cool - sounds very interesting; I will definitely dig in.




2. you already have a pet-shop based on wicket but want to extend it with
some informational area - could you just embed brix into it or would this

you can pretty much just drop brix in and map it to a subset of url space.


sounds very impressive - its hard to believe that Brix offers so much 
flexibility, so im quite impressed by now. Thanks for your fast response

FactoryPattern + Forms/ Enclosures + Feedback

[Korbinian Bachl - privat]

Hello,

Ive got 2 problems,

1st;
I tried the FactoryPattern with form components like TextField and now
have the problem, that due to the recreation of the FormFields by the
Factory the inserted value into the model gets lost in case of a invalid
form submit (e.g: error in one field = all entered value is lost). I 
think this is because the Factory always generates a new one;


code is this (just 1 example):
ListIRapidFormPanelFactory flist = new 
ArrayListIRapidFormPanelFactory();

flist.add(new IRapidFormPanelFactory() {

public RapidFormBasePanel getFormPanel(String id) {
return new TextFieldRapidFormPanel(id, LABEL, 
NOTE, model.bind(field));

}
});

The model itself is a final one - how can I make sure that these 
formfields behave like they should (not loosing their input in case of 
valid errors)?



2nd;
how can I bind an wicket:enclosure to a feedbackform? I tried to 
override the isVisible()

of the feedback by

isVisibel() {
return anyError();
}

but that didnt work; What would the optimal code be to use it?


Best,

Re: Strange behavior of wicket-security libraries in netbeans

[Korbinian Bachl - privat]

AFAIK the packages have changed between the Versions, so NB cant find 
them (thats correct though); try a full recompile (the one with delete  
recompile) and you should get the wrong classes in the output; there hit 
the link to the classes and issue an Fix Imports via the right context 
menu, that'll do it;


Hope that helps,

Hello Wicket people,

I'm experiencing a strange behavior of Netbeans (6.0.1) IDE working with
Wicket-Security components. Maybe this question is more Netbeans- than
Wicket-related, but I thought I'd better ask here first.

I have a BaseSecurePage class that implements ISecurePage.
Its constructor looks like this:

public BaseSecurePage() {
  super();
  setSecurityCheck(new ComponentSecurityCheck(this));
}

Wasp-0.1 and Swarm-0.1 were included in a library class Wicket-Security-0.1
in Netbeans IDE and everything was fine.
Once I created Wicket-Security-1.3, added Wasp-1.3 and Swarm-1.3 in it,
removed old Wicket-Security-0.1 and added the Wicket-Security-1.3 to the
project, strange thing had happened:

Netbeans now says it can't find symbol ComponentSecurityCheck(this).
Moreover, when I Ctrl+click the ComponentSecurityCheck(this), it takes me to
the sources (which I didn't import, just swarm/wasp-1.3.0 and
swarm/wasp-javadoc-1.3.0), and there in the sources of
ComponentSecurityCheck I can see Netbeans complaining about the fact that it
can't find Component class.

There's one good thing though -- it builds with no problems, but still I'd
like to fix somehow.

Follow-UP:

I solved the problem I had with the listView; it works as expected if 
you do a


.setReuseItems(true); to the ListView

However, the problem with the wicket enclose to a feedBackPanel still 
exists... this one wont work;

Re: Removing the jsessionid for SEO

Hi Rüdiger,

AFAIK this could lead to some punishment by google, as he browses the 
site multiple times using different agents and origin IPs and in case he 
sees different behaviours he thinks about cloaking/ prepared content and 
will act accordingly to it;

Yeah, it would be nice if the google bot would be as clever as the one from
yahoo, and just remove them himself. But he doesn't.

So I implemented a Servlet-Filter which checks the user agent header for
google bot, and skips the url rewriting just for those clients. As this will
generate lots of new sessions, the filter invalidates the session right
after the request. Also, if a crawler is doing a request containing a
jsessionid (which he stored before the filter was implemented), he redirects
the crawler to the same URL, just without the jsessionid parameter. That
way, the index will be updated for those old URLs.

Now we have almost none of those URLs in google's index.

If anyone is interested in the code, I'd be willing to publish this. As it
is not wicket specific, I could share it with some generic servlet tools OS
project - is there something like that on apache or elsewhere?

But maybe Google is smarter by now, and it is not required anymore?

Re: Removing the jsessionid for SEO

[Korbinian Bachl - privat]

Hi Jeremy,

youre absolutely right; Nearly all spiders today can handle the default 
sessions, may it be Java, PHP, .Net etc. ; those guys at google and 
mircosoft arent beginners!


And its also important to understand that a URL with wicket in fact is 
to a part nothing more than a plain string that can be manipulated the 
way you like. Wicket (a.k.a. your page) needs 1 or maybe 2 parameters - 
and it has to know how to find them, the rest of the URL can be messed 
with so it fits to your needs as long as you can garantue the unique 
behaviour of content-to-URL so you dont get marked as duplicate content 
spammer;


Best,

Jeremy Thomerson schrieb:

If I understood you correctly, the first page is bookmarkable, the second is
a wicket URL, tied to the session.  That'd be bad for SEO - search engines
couldn't see page 2, or they would, but the URL is tied to their session, so
even if a user visited that URL, they wouldn't get that page.  This means
that any content past page one is unreachable from a search engine.  I had
another thread going about a problem I was having with sessions, which
turned up some interesting data.  I have over 31,000 pages indexed by
Google, they are visiting bookmarkable URLS that DO have jsessionid in them,
but only two pages in their index have a jsessionid in them.  They obviously
handle jsessionid fine these days, or at least they are for me.

If you need all of your content to be indexed, you really need to concern
yourself with making every page bookmarkable.  Take a look at Korbinian's
comments above - it looks like he is doing it well.  Or have a look at my
comments or my site http://www.texashuntfish.com.

You should specifically look at http://www.texashuntfish.com/thf/app/forum -
I am using DataTable's there, but every link (including sort, etc) is
bookmarkable.  So, you may go into a category and get an URL like
http://www.texashuntfish.com/thf/app/forum/cat-53/Let-s-Talk-Texas-Outdoors-Classifieds-Buy-Sell-Tradeor
http://www.texashuntfish.com/thf/app/forum/18395/Winchester-22-model-61-for-sell.
The cat-53 or the /18395/ are the only things that matters.  I have a
strategy mounted on /forum that will take the first parameter and use it
to decode what kind of page is being requested - a category page, or a
specific post, etc.  Everything after that first parameter is specifically
for SEO.

Putting good keywords in the URL like that, and putting the subject of every
article / calendar event / news or forum thread is what shot us up in the
rankings of multiple search engines.  Migrating the app from what it was
before somerandomscript.cfm?foo=123123bar=12321 to this made a HUGE
difference.  It wasn't without work - Wicket is super easy if you don't have
to worry about URLs - but they also make it easy to totally customize all of
your URLs, too.

Shoot back any questions you have.  Hopefully I can share more information,
or even some code later.  Maybe Korbinian and I should put some information
on the Wiki about pretty URLs and SEO.

[Korbinian Bachl - privat]

Hi Erik,

you might want to use IndexedPageParams, so you could do:

mount(/myPath, myForwardClass.class); in init;

the parameter with index 0 is the first one, the index 1 is second and 
so on, delimiteds are the ones by /


eg:

myapp.com/myPath/param0/param1/param2 ... and so on;

alternatively you can use 1 named param (here example) and have the real 
URLs be manipulated by replacing each / to some kind of letter that 
doesnt exist in your target-scheme, eg: / - _


so you get myapp.com/myPath/example/mytarget_myfile.ending

- your param example then holds mytarget_myfile.ending wich needs 
to be rechanged then;


the page itself might hold a simple Label that displays the content 
based on the params;


Hope that helps to get started,

Best,

Korbinian

Hi,

I am looking for a way to serve many static images. It is important that
I do not have to separately register them (as with SharedResources, as I
understood) as there about 20.000 to 50.000 of them, and the set changes
continuously.

The most obvious thing that comes to mind is a static resource that
takes parameters that are extracted from the URL (similar to Page). But
I could not find such a thing.

I am now considering implementing a servlet, but I'd rather stay within
the framework.

Re: @SpringBean in init

[Korbinian Bachl - privat]

Hi Mathias,

in short: you cant;

the @SpringBean injection is usually done before the class is really 
created so at a time wicket and spring aren't registered yet;


What you could do (not 100% sure) would be to call a simple proxy-pojo 
that gets you the data (even maybe a LoadableDetachable one?) during 
startup - so the firs request to @SpringBean is done after the creation 
and initalisation of the application class (and the line with the 
SpringComponentInjector).


Maybe it could also try to use your needed bean without the spring call 
but instantiate it directly?

SpringWebApplication is not a Component so this:
addComponentInstantiationListener(new SpringComponentInjector(this));
doesn't matter here.

Before you want to use this @SpringBean in your init() method you should call:
InjectorHolder.getInjector().inject(this);

But then you should use AnnotSpringWebApplication or manually setup
injector in InjectorHolder:
InjectorHolder.setInjector(new AnnotSpringInjector(getSpringContextLocator()));

Re: localizer and variables

[Korbinian Bachl - privat]

well, in your case its not an easy string, but one with 2 parameters - 
in case you have a plain string you can also use the wicket:message 
method that is quite better suited for this (e.g: 2 message blocks - 1 
before, 1 after and in middle a simple label that spews out the user data);


if you need many hard facts inserted into many strings holding many 
parameters it might be easier to supply different language-markups (aka: 
i8n of whole page in wiki) all over (however, im not sure how your email 
thing works under the hood);


here in your case I could imagine that having several

mailcontent.html
mailcontent_en.html


might be easier so you just put in the hard facts using simple label; if 
its just this one line however your solution is best IMHO;

Re: wicket, spring and aop

[Korbinian Bachl - privat]

Hello,

im quite new to spring, but afaik you cant have spring manipulating 
wicket itself; however you could create a spring based proxy-class for 
those purposes and have it used by @SpringBean(name=name) where you 
put the logic in it;


maybe its possible to have a wicket-PageClass be also a managed by 
spring but im not sure if this works...


Is spring spewing out its lines at your current app startup? (if not: 
http://cwiki.apache.org/WICKET/spring.html helds details for this)

Hi there,

I'm just trying to integrate wicket 1.3.2, spring 2.0 and aspect oriented 
programming (spring-aop). I've an aspect for instrumenting a dao provider that 
is defined as follow:

@Aspect()
public class DaoProviderInstrumentation {

@Around(execution(* *(..))  target(org.mypackage.dao.DaoProvider))

public Object executeFinder(ProceedingJoinPoint pjp) throws Throwable {
   // stuff not important for now
}

A dao provider is intended to be an interface similar to the following:

public interface Daos extends DaoProvider{

 public AnimalDAO getAnimalDao();
}

where AnimalDAO is another interface with methods to retrieve animals. The 
instrumentation should get executed when i'm trying to access to the getAnimalDao() and 
it should create a proxy of animalDAO that exposes finder methods to retrieve 
animals using some conventions defined by name of the methods.

The instrumentation isn't executed. I know wicket is not managed but i like the 
wicket framework and it would be great to use integrate it but i don't know if 
it is possible and what is the correct way of doing it.
I've tried to use the SpringWebApplication in the wicket-spring package  but i 
don't know how to use it to integrate the instrumentation.

I don't need to inject components using the @SpringBean annotation.

Thanks for your time,

Re: Removing the jsessionid for SEO

[Korbinian Bachl - privat]

Hi Jeremy,
Hi Dan,

for a project long ago I had the trail of making a product-browser SEO 
friendly; I used a plain PagingNavigator at first, and then extended it 
to have it to use the IndexedUrlPageParameters; this allowed me to put 
anything into the path to have a nice URL;


the key here is to look at the URL and treat it as a unique resource 
line; so I did it sth like that:


mountName{(/anyparams)}*{/pageNumber}

this gave me the possiblity to have a browsing URL where I could put 
anything in while the rest still works; remember also that the URL for 
SEO may (!) change in future, so go for maximum flexible designs, up you 
see a resource, then any params to feed the spider (there may be 0 to 
over 10) and a hook at the end that has to be a number (where 0 is 
pretended in case nothing at the end is a number);


so I was able to finally let the spider see things like:

e.g:
product/brand_New/BestItemOfTheWorld
product/specialCategory/moreSpecial/moreInfo/2
product/spcialCategory/moreSpecail/brandName/moreDetails/1

etc.

now, you wonder if I feed the spider with this how do I know where to 
end?  the key was that the part between got merged internally and was 
specified by the application so we overcome the problem of:


a, recreating the view that should be the right one (here: we had a 
tree-like behaviour for our products where we could compare to the tree 
in database)


b, duplicate content (very bad! - never, ever have a spider find the 
same content (or very very similar!) under more than one URL !)


this strategy did very well; Today with wicket 1.3 I would go nearly the 
same but stick to the HybridURL scheme, and maybe try to be even more 
flexible with URL scheme by having the basic schemes and resources 
specified in persistence (URL-hook, initialState); Remember it is 
important to feed same resources under same URLs out, else the spider 
will think you might try to fake content for him;


The jsessionID is sth. I dont care about anymore - its 2008, spiders 
knows it and the usual visitor/ surfer has no clue how to different a 
URL from an emailadress; however many people have turned cookies + JS 
off because of security fears - in turn the JSessionID will concern only 
few people who know about some details but hamper many people that have 
no knowledge of the internet and its techniques all over - IMHO.


@Jeremy: your aproach also seems interesting to me, can you give more 
details about it?


Best,

Korbinian

Re: YUI integration?

[Korbinian Bachl - privat]

Hello,

im currently the only one on it, and I have very short time currently.

wicketstuff-YUI is currently at 2.4.1, but 2.5 is a problem as they had 
some api-changes, which means it isnt a drop in replacement. The trouble 
is IMHO that they (YUI) havent made their homework first by completing 
the YUI Loader to final (it still has bad quirks :( - for example in 
YuiEditor its ok to use it only if you dont need the picture adding 
dialog, as the necessary CSS is missing... ) wich means updating to 2.5 
= changing all JS of all components to new one;


If you have some time however you may feel free to go for it. But please 
note that you currently cant use YuiLoader because of the problems 
mentioned above.


Best,

Korbinian

 hey igor thanks for all the help I really am learning a lot here.

 I am having an issue forwarding the model tp my textfiled in my panel
and I
 wanted to show you my code and see what you thought the issue is. I am
sure
 it is something simple I have overlooked.

 Template.java
 public class Template extends WebPage {
 private String teststring;
 Form form = new Form(myform) {
protected void onSubmit() {
callDatabase(teststring);//this is always coming back
null and I am not
 sure why.
};
 };
 form.setMarkupId(myform);
 form.setOutputMarkupId(true);
 add(form);
 form.add(new FeedbackPanel(feedback));
 form.add(new TextFieldPanel(textfield, new PropertyModel(this,
 teststring)));
 }


 Template.html
 body
form wicket:id=myform
  all feedback messages go here!
  TextFieldPanel go here
/form
 /body

 TextFieldPanel.java

 public TextFieldPanel(String id, PropertyModel pm) {
  super(id, pm);
  add(new RequiredTextField(textField1, pm));
 }


 TextFieldPanel.html
 wicket:panel
 input wicket:id=textField1 type=text/
 /wicket:panel


 Now I was thinking that since I sent the PropertyModel to the
TextFieldPanel
 it should work but it did not. Is there an inheritance that i need to do
to
 get this to work? The goal here is to create a bunch of textFields on
the
 fly but first I would like to get this working so I know what I am doing
 hince the simple example of my code.

 Thanks again for the help

WicketWebBeans

[Korbinian Bachl]

Hi,

i just wanted to have a look at it but im somehow stuck.

First I wanted to get it from src so I checked out the 
wicketwebbeans-examples from trunk and did:


mvn install

error:

GroupId: net.sourceforge.wicketwebbeans.parent
ArtifactId: WicketWebBeans-parent
Version: 1.0-SNAPSHOT

Reason: Unable to download the artifact from any repository


net.sourceforge.wicketwebbeans.parent:WicketWebBeans-parent:pom:1.0-SNAPSHOT

from the specified remote repositories:
  central (http://repo1.maven.org/maven2),
  javax.jdo.snapshots (http://www.jpox.org/downloads/maven-nightly)

so, as you dont specify the correct repo in the pom.xml, wich one holds it?


Then i downloaded the 1.02rc from Sourforge (the examples.war) and 
loaded it into tomacat, but when opening the root of it 
127.0.0.1:8080/wicketwebbeans-examples/ i get a 404error - so whats the 
correct deeplink? And why is there no redirect to it installed?


regards,

Korbinian


PS: both examples (the 1.3 wicket and the 1.2.6) also spew out an error 
saying that no log4j config file is existing

Re: MyWebApplication, SpringWebApplication + AuthenticatedWebApplication

[Korbinian Bachl]

Hi Dan,

I know the wiki - but this somehow confuses me... in the Wicket-Examples 
all Springapps are extending SpringWebApplication - and that file has 
more than just a line in the init()... -


No If I look at the SpringWebApplication I doubt that they would provide 
all those lines in it if a simple line in the init() would be enough?


I mean if I just do:
e.g:
 addComponentInstantiationListener(new SpringComponentInjector(this));

like you said why are they doing all this then in the SpringWebApplication

e.g:
public abstract class SpringWebApplication extends WebApplication
implements
ApplicationContextAware
{
private ApplicationContext applicationContext;

/**
 * Singleton instance of spring application context locator
 */
	private final static ISpringContextLocator contextLocator = new 
ISpringContextLocator()

{

public ApplicationContext getSpringContext()
{
Application app = Application.get();
return 
((SpringWebApplication)app).internalGetApplicationContext();
}
};
.
---

as well as more things - arent this needed?

Best,

Korbinian

Hi,

usually my WebApp is based on Wicket-Auth-Roles, so I do:

MyWebApp extends AuthenticatedWebApplication {


Lately I played around with spring 2.5 a bit and so used

MyWebApp extends SpringWebApplication {

but how can I now integrate a SpringWebApplication to use Wicket-Auth-Roles?

The only way I currently see is to copy'n paste the content of the 
SpringWebApplication into MyWebApp and let it extend 
AuthenticatedWebApplication - but copy'n paste is not my preferable way 
however...


Any ideas?

Wicket + Spring 2.5

[Korbinian Bachl]

Hi,

im currently using ANT + IDE (EAR having EJBapp + WEBapp) to get my 
wicket apps started, but somehow I looked at the new spring 2.5 and it 
seems interesting to me (same possibilities but no big appserver 
needed)... can anyone post a example app or structure to me where I can 
see how to plug wicket + spring 2.5 together? (or a Maven2 Archetype for 
it?)


I mean, where do you stere there? first a spring 2.5 App and then put 
wicket in? or wicket first and then spring in?... sorry for the noobish 
question but I never used spring before.


Best,

Re: How to secure passwords?

[Korbinian Bachl]

This is nothing about wicket - its about base security. MD5 is a 
hash-algorithm (see: http://en.wikipedia.org/wiki/Md5) which is no more 
secure (flaw found 1996) as there are tables to reverse given md5 (from 
2003 on) to a valid input


if you need security youre best with SHA at the moment, that has a 
greater length than the 128 Bit of MD5 and therefore more non-collision 
space - have a look here: http://en.wikipedia.org/wiki/SHA_hash_functions


the implementation is available in java itself have a look at these 
examples here:

I've a little question with wicket: I would like to hash my users' passwords

Is there a way to achieve this?

thank you for your answers. I know that MD5 isn't much secure, but it
doesn't matter (I just want to obfuscate them, to prevent an admin to get a
clear password from his admin console). But I agree, SHA may be better...


to get a wanted md5 collision requires a person that uses a rainbow 
table under 1h time by a successrate at about 99,9% - 
http://www.antsight.com/zsl/rainbowcrack/




I guessed there was a wicket way to 1) crypt some data before sending them
out of the client's browser (so it doesn't travel in clear) 2) compare it on
the server side with the required hashed password.


you want to use SSL (TLS now called) for this! - go to a banklogin and 
you see changing the http://www.mybank.com to https://www.mybank.com


see http://en.wikipedia.org/wiki/Transport_Layer_Security for a overview




I know how to write the crypto algorithm... I just don't know the best way
to integrate it into wicket. However, I saw some interface on Wicket (like
ICrypt) and guessed there is a way to use it well...


1. there are under 100 people on this planet that know how to write a 
secure crapto algorithm - and believe me that we two arent anywhere near 
them :)


2. AFAIK the ICrypt is good for obscuring the URL itself - not for the 
content (but im not sure on this)




Thank you for your interest ;)


youre welcome,
