See this demo app
https://github.com/wicketstuff/core/tree/master/jdk-1.5-parent/phonebook
Also check the maven archetypes at http://www.jweekend.com/dev/LegUp. This
will create a mini app which you can extend with your application details

via jmx I could see that only 45 sessions were there
and that the PeakNumberOfActiveRequests was also 45.


Do you have any idea ?

It's fixed in trunk.
If you can use trunk for your tests I'll be thankful for feedback.

Help I need to understand page locking

[Jim Pinkham]

I'm using wicket 1.5 RC3 and just started getting some total system lockups
recently in prod that I can't understand.

Once it gets into this state, the only remedy is to restart tomcat.
Unfortunately, I haven't yet figured out how to reproduce this, so meanwhile
I thought I'd ask if someone could please help me understand how page
locking works in general and what I should be looking for.

When I think of locking I usually think of threading, so not sure if it
matters, but I do start one a thread for email sending with the Application
thread local set for it also (because I manage data sources thru the app so
it was easier that way).  I could try refactoring that, but without a
reproducable test case, it's just a guess at this point.  My other plan
would be to revert to some older wicket version, but again, just a guess.

Here is the stack trace; nothing unusual precedes it.  (This is just a user
trying to visit the home page).  The only thing I notice is that these
issues all seem to be using the PageParameter version of the page
constructor.

tomcat stuff omitted..

Re: Help I need to understand page locking

[Martin Grigorov]

Wicket 1.5 locks access to the same page instance by more than one thread at
a time.
You can set log level to DEBUG
for org.apache.wicket.page.PageAccessSynchronizer class and see which thread
acquires the lock for page with version 0 and never releases it.

Instead of going to previous version of Wicket better go to a newer one.

Re: Help I need to understand page locking

[Jim Pinkham]

Thanks, good tip.  I'll do that, and I'm also going to send in a replacement
copy for PageAccessSynchronizer that still has the one minute delay, but
then if it fails, it forces the lock anyway and swallows the exception -
hopefully that will solve my lock ups until I can find the cause:

locks.put(pageId, lock);  // force it - temporary fix only
logger.error("failed to acquire lock would have thrown: ",
/*throw*/ new CouldNotLockPageException(pageId,
thread.getName(), timeout));


Thanks,
-- Jim.

[Tomasz Dziurko]

You should use method:

final FeedbackPanel setSortingComparator(Comparator
sortingComparator)

and create comparator which will sort FeedbbackMessages in proper order (in
your situation probably those with feedbackMessage.component instanceof Form
coming first)

Google Chrome and Apache Wicket, an awesome combination

[Brown, Berlin [GCG-PFS]]

FYI...
 
I usually ask questions but I thought I post a comment about google
chrome.  The chrome browser has default web debugging that is similar to
firebug.
 
With Firebug, it is more difficult to detect the wicket ajax rendered
content but comes up automatically in chrome.  Also speed wise, chrome
renders much faster than IE or Firefox.  I tested Ajax oriented complex
content and chrome just works quickly.

Re: Google Chrome and Apache Wicket, an awesome combination

[Zilvinas Vilutis]

And that is why the "user acceptance testing" must be done on IE & FF :)

Re: Google Chrome and Apache Wicket, an awesome combination

[Martin Grigorov]

Well, I don't share your opinion here :-)

Chrome Dev tools have no "persist console content" - once you reload the
page all the logs are gone. There is a RFE for that and I voted for it.
Also I miss the 'Net' tab.
Also Firefox's WebDeveloper tools are much better than current state in
Chrome and its extensions.

Re: facebook like iframe in wicket

[labano10]

@Igor, my main problem actually is updating the src attribute of the iframe
at run time because that's what facebook uses to construct the like button.
The href part(within src) constitutes of the url of the page being liked
with escapes(%3A for : and %2F for /). I want to update especially this part
at run time. How do I do it in wicket. I am currently checking out the
wicket velocity see if it can help. Do you have any other idea, sorry I may
not have been clear initially.

BookmarkablePageLink with PopupSettings

[Jered Myers]

I am attempting to open a new browser tab to a bookmarkable page.  The 
constructor of my page is being called twice.  Is there a way I can 
prevent this from happening?  When I remove the PopupSettings the 
constructor is only called once, but the page does not open in a new tab.


Here is an example fragment of my implementation in Wicket 1.4.16:

ApplicationClass.java... mount(new 
QueryStringUrlCodingStrategy("MyPage", MyPage.class));


MyPageLink.java
public class MyPageLink extends BookmarkablePageLink
{
  public MyPageLink(String id, IModel identifierModel)
  {
 super(id, MyPage.class);
 setParameter("Identifier", identifierModel.getObject());
 PopupSettings popupSettings = new PopupSettings( blah | blah | 
blah); <-- Only PopupSettings.blah here

 setPopupSettings(popupSettings);
  }
}

MyPage.java
public class MyPage extends WebPage
{
public MyPage(final PageParameters params)
{
   super(params);
}
}

Re: wicket showing traces that we used wicket is it a problem

[Maarten Billemont]

I can only imagine it fits in the "security through obfuscation" category.  "If 
they don't know it's Wicket, they won't think to use a Wicket exploit on it!".

At any rate, I'd be more worried about the fact that you're running it in a 
Java VM than the fact that the front-end of it is generated by Apache Wicket.
If anything is going to be exploitable to do anything useful, it's going to be 
the VM.  Or more likely, your own code.

Don't get sucked into this obfuscation crap.  It buys you nothing.  But if you 
must, feel free to mount your pages with a .php extension and exhaust all the 
script kiddie's patience in his attempts at SQL injection.

MetaPattern Usage

[Phil Franken]

Can someone give me an example of how to group MetaPatterns?  For 
example if I want to allow MetaPattern.WORD and 
MetaPattern.EXCLAMATION_POINT...

Re: wicket showing traces that we used wicket is it a problem

[hariharansrc]

i am just a beginner so i am just asking, it may cause a problem if any
security holes we found, other than that i am worrying about   nothing. I
feel very comfortable to use java in development especially wicket and
hibernate. So, i have no plan to switch to .net or php at any cost. Even 
will just make my friends also to use wicket and java  because of its ease.
thank you for replies

then i am having a another small clarification

whenever i deploy a application using wicket i get https i am using
websphere server is it the default mode of wicket or it is because of any
other  reason. how to switch between https and http. is it something related
with stateful nature of wicket

[Igor Vaynberg]

by default wicket does not enforce https. it does, however, give you
an easy way to switch - just google it.

Re: BookmarkablePageLink with PopupSettings

[Martin Grigorov]

put a breakpoint in your page constructor and see why it is called twice
