wicket + JSON web tokens

2015-07-28 Thread Jason Novotny

Hi,

Has anyone done any work with Wicket and JSON web tokens http://jwt.io/? 
I'm interested in getting away from server-side session management if 
possible.


Thanks, Jason

Hi,

Register a
http://docs.oracle.com/javaee/6/api/javax/servlet/http/HttpSessionListener.html
and print the stacktrace in #sessionCreated(). This way you will see where
HttpServletRequest#getSession(true) is being called.
For some reason your web container doesn't recognize old session ids and
creates new sessions.

distributed session handling with redis

2015-07-26 Thread Jason Novotny

Hi,

I googled and found a discussion on using redis to handle sessions, and 
someone also came up with a project 
https://github.com/baholladay/WicketRedisSession.


Based on the thread 
http://mail-archives.apache.org/mod_mbox/wicket-dev/201502.mbox/%3c54e4cfee.80...@gmail.com%3E 
I wound up using spring-session with redis as per 
http://docs.spring.io/spring-session/docs/current/reference/html5/guides/httpsession.html


I see I would also need to modify the page manager provider-- is it 
sufficient to add the following, or is there more to do?


setPageManagerProvider(newDefaultPageManagerProvider(this) {
protectedIDataStore newDataStore() {
return 
newHttpSessionDataStore(getPageManagerContext(),newPageNumberEvictionStrategy(20));
}
});

Thanks, Jason

wicket-annotations and page mounting

2015-07-10 Thread Jason Novotny

Hi,

I'm using wicket-annotations and I've added:

newAnnotatedMountScanner().scanPackage(com.foo.web.pages).mount(this);

in my Application class.

My page classes all have:

@MountPath(value =summary)

However, I want to adjust the pages to not use query parameters like account=5 
and use / like account/5 instead.

Is there a way to set this across the app, just like scanPackage, or do I have 
to set this on each page in my application?

I'm using latest Wicket 6.

Thanks, Jason





ajax events and manipulating DOM

2014-11-14 Thread Jason Novotny

Hi,

I'm using jquery datatables which allows customization of table header 
by creating html in javascript via dom attribute which creates a div :


$('#datatable').dataTable({

dom: 'topdropholderpostponebtnsholdeript',
language: {
info: _START_-_END_ of _TOTAL_,
search: 
},
aaSorting: [],
aoColumnDefs: [
{'bSortable': false, 'aTargets': [ 0, 4, 7 ] }
],
'iDisplayLength': 12
});
$('.btns').html('buttonclass=btn btn-primarytype=buttonSend/button');


However I need these buttons to be server-side actions.

My naive solution was to create additional wicket links on the page:

div  class=actionbuttons
button  wicket:id=cancelclass=cancel-order-btn 
btntype=buttonCancel/button
button  wicket:id=sendclass=btn btn-primarytype=buttonSend/button
/div

and then at the top of my page:

script  type=text/javascript
$(function() {
updateDataTable();  
});
/script

where I have

function updateDataTable() {

$('#datatable').dataTable({

dom: 'topdropholderpostponebtnsholdeript',
language: {
info: _START_-_END_ of _TOTAL_,
search: 
},
aaSorting: [],
aoColumnDefs: [
{'bSortable': false, 'aTargets': [ 0, 4, 7 ] }
],
'iDisplayLength': 12
});

var html = $('.actionbuttons').html();

$('.btns').html(html);
$('.actionbuttons').remove();

}
}

However, the send button when clicked needs to refresh the panel with an 
updated data table. So I have:


add(newAjaxSubmitLink(send) {
@Override
protected voidonSubmit(AjaxRequestTarget target, Form? form) {
container.addOrReplace(createDataTable());
target.add(container);
target.appendJavaScript(updateDataTable());

}
});


Now this works the first time when the page loads. It removes the DOM 
section with wicket-ized links to the DOM section of the datatable. 
Clicking send results in an updated table. However, when I click 
send again, although the display looks good and it has replaced the 
DOM, the links seem to have no events associated and it doesn't do 
anything. I wonder if a disconnect is going on with the wicket event 
registration...


Is there a better way to do this, or am I missing something?

Thanks, Jason







Re: ajax events and manipulating DOM

2014-11-14 Thread Jason Novotny


Ok, to answer my own question, it was a jquery/javascript issue. Instead 
of removing dom, the approach that works is to use appendTo instead:


$('.actionbuttons').appendTo('.btns');

wicket + jsessionid and 302 issues

2014-11-12 Thread Jason Novotny

Hi wicketeers,

I was hoping to get rid of the jsessionid that appears in the 
browsewr bar when running my wicket app under Tomcat 7, and I added the 
following to web.xml:


session-config
session-timeout30/session-timeout
tracking-modeCOOKIE/tracking-mode
/session-config

However, now in production we get all these 302 redirects which are 
causing an infinite recursion. What is the best way to handle this? I 
also found a wiki page 
https://cwiki.apache.org/confluence/display/WICKET/SEO+-+Search+Engine+Optimization 
but wasn't sure if this also applied to using Wicket 6.

Re: wicket + jsessionid and 302 issues

2014-11-12 Thread Jason Novotny

Hi,

I figured more detailed config info would be helpful. I want my 
production app to be accessible via https only. The connection is SSL to 
our Apache load balancer which is then http to our Tomcat7 instance.

The Tomcat 7 connector is default:

 Connector port=8080 protocol=HTTP/1.1
   connectionTimeout=2
   redirectPort=8443 /

Just not sure how to config the web.xml or if my tomcat config needs 
changing.

wicket6 + sso and redirects

2014-11-03 Thread Jason Novotny

Hi,

I'm adding support to my application use SSO outbound from my webapp to 
an Identity provider (IP) to authenticate a user from my webapp to an 
external web application.


I have SSO code and the steps involved on my page are:

1. send redirect to

https://www.3rdparty.com?authnReqRedirectUrl=myurl

where myurl is a wicket page e.g. /sso

2. Now the wicket page at /sso should receive a SAMLRequest parameter, 
which is then used to create a SAMLResponse


3. The SAMLResponse should be posted back to the 3rd party thru a form:

form wicket:id=form method=post action=third party url
input wicket:id=samlresponse type=hidden/
input type=submit value=Submit/
/form

I believe the form can be auto-submitted thru javascript:

script type=text/javascript
window.onload = function () {
document.forms[0].submit();
}
/script

And then the user should land on the 3rdparty web application.

So basically my question is how do I do step 1, I'm using wicket6 and tried:

add(new AjaxLinkVoid(test) {
@Override
public void onClick(AjaxRequestTarget target) {
throw new 
RedirectToUrlException(https://thirdparty.com?authnReqRedirectUrl=https://mysite.com/sso;);

}
});


But seems that it doesn't return to my wicket page mounted at /sso. Am I 
doing this right?


Thanks, Jason

Re: jquery DataTable + wicket Cannot bind a listener

2014-10-28 Thread Jason Novotny


Hi Martin,

Are there examples? What about this simple piece of code...

WebMarkupContainer tbody = new WebMarkupContainer(tbody);
tbody.add(new AjaxEventBehavior(onclick) {
@Override
protected void onEvent(AjaxRequestTarget target) {

}

protected void updateAjaxAttributes(AjaxRequestAttributes 
attributes) {

super.updateAjaxAttributes(attributes);
attributes.setChildSelector(td);
// TODO what do i do here?
}
});


Thanks, Jason

On 10/28/14, 1:10 AM, Martin Grigorov wrote:

Hi,

You should read about JavaScript event delegation. This is what they
recommend.

Wicket has basic support for this
with org.apache.wicket.ajax.attributes.AjaxRequestAttributes#setChildSelector.
I.e. you can register an Ajax behavior on the table or tbody and use
childSelector to listen for events only on specific children, e.g. 'tr',
'td', 'td div', etc.

This is more lightweight than using Wicket's built-in AjaxLink, but it is
also a bit more complex for you as an application developer.

Good luck!

wicketAjaxGet and wicket 1.5 and StalePage exceptions

2011-11-10 Thread Jason Novotny


Hi,

Recently converting an app from wicket 1.4.18 to wicket 1.5.2 and 
am now seeing stack traces like the following:


org.apache.wicket.request.mapper.StalePageException
at 
org.apache.wicket.request.handler.PageProvider.getStoredPage(PageProvider.java:302)
at 
org.apache.wicket.request.handler.PageProvider.resolvePageInstance(PageProvider.java:257)
at 
org.apache.wicket.request.handler.PageProvider.getPageInstance(PageProvider.java:165)


I've tracked it down to a wicketAjaxGet request invoked on the client 
that looks something like this:


var wcall = wicketAjaxGet(url + args, function() { }, function() { });

url looks something like: 'myBuildings?52-1.IBehaviorListener.2-' which 
I create from AbstractDefaultAjaxBehavior.getCallbackUrl().toString()


It seems the problem has to do with page versioning not matching the 
page on the server.


Is there a workaround or another way to code this up? Let me know if I 
can provide any additional information.


Thanks, Jason



mouse over table cells and dialog popup with ajaxlinks

2010-09-20 Thread Jason Novotny


Hi,

I have a fairly complex use-case scenario: I want a dialog to popup 
when a hover event occurs within a table cell. The dialog will provide 
a couple of links (ideally AjaxLink) that should trigger a wicket ajax 
event.


I can imagine maybe creating the dialogs all on the client so there 
is no need to hit the server when the mouse hovers over the table cell

Re: mouse over table cells and dialog popup with ajaxlinks

2010-09-18 Thread Jason Novotny


Thanks!

My real concern isn't so much the creation of the dialog/tooltip 
but how do I create a wicket appropriate link in that dialog/tooltip in 
order to edit the item that is contained in the table cell?


Thanks again, Jason

Jason,

I do a similar thing for one of my applications. I have a table and
when the user hovers the mouse over some button on each row then I
show a dialog with more details about the row. What I do is having a
hidden div next to the table and make it appear, its contents updated
via AJAX, with the help of a jquery plugin: I use plugin shown in [1]
in combination with grid shown at [2]. For other use cases, when
dialog contents are very heavy I use a ModalWindow triggered by an
onclick.

Maybe I could strip my code of the business logic and post it
somewhere so that you could use or adapt it.

autocomplete text field with dropdown style functionality

2009-11-05 Thread Jason Novotny

Hi,

   I'm using the autocomplete text field with great success. However, 
I'm looking for a way where a user can start to move down the list and 
once they are at the last choice, it will continue to pull new items 
back from the server. If this seems confusing let me explain with my 
use-case:


   I have a State autocomplete textfield. Initially they enter C 
and get all the states that start with C. As they go down the list and 
say first California is highlighted and then Colorado and then 
Connecticut I would like the list to display Delaware (possibly even a 
few more like Florida and Georgia) as the next entries available even 
though a C was entered into the text field. It seems I would need to 
know that the last option was selected as a trigger to make a call to 
display more items from the server. Does anyone have any idea how to do 
this?

Re: Wicket HTML before graphics design with CSS ...

2009-10-28 Thread Jason Novotny


   My best experiences have been when the designer has full reign to do 
what they need on the CSS/HTML front on a blank canvas-- obviously after 
doing wireframes with something like OmniGraffle, Balsamiq or Fireworks. 
It helps if they add things like static error messages or a highlighted 
tab so the wicket developer gets a sense of when they will probably do 
some kind of onComponentTag override to change a class or HTML 
attribute, etc. Things that screw up designers IMO are repeaters... it's 
hard sometimes for them to know to what degree the layout structure is 
created on the server side. For instance I really like the DataBrowser 
component where it provides pagination, sorting, zebra stripes, etc, but 
the designer just sees a table wicket:id=sometable and thats it. 
Obviously they can still style it but the entire structure is hidden 
from them. OTOH ListViews and others expose more structure to the 
designer which makes them feel closer to home. It's all a tradeoff 
really. The biggest rule I give is to just know that any tag with 
wicket:id in it means that behavior to some extent is controlled on the 
server side so beware. I like this model as a developer since I really 
enjoy taking a nice looking static page and making it come alive, as 
opposed to my own crappy HTML since I can't design worth beans. I've 
also found subtleties where you really want the design up front, one 
concrete example was a tabbed pane. In one case the styles were applied

as

ul
li class=selectedaone/a/li
...
/ul

or another as

ul
li
a class=...one/a
/li

These are subtleties that the designer can change on the fly rather 
easily, but in wicket it makes a huge difference. I wouldn't want to 
force the decision on the designer, this should be their choice.


But this is just my 2 cents

jquery ui dialog and ajax component updating

2009-10-27 Thread Jason Novotny


Hi,

   I'm not sure if this is a jquery or wicket problem I'm having. I am 
using wicket ajax to update (replace) a panel component with a link


AjaxLink link = new AjaxLink(link) {
   public void onClick(AjaxRequestTarget target) {
   summaryDialog.displaySummary(my summary, target);
   }
   };

that when clicked will display the summary dialog that contains a Jquery 
dialog component I created called SummaryDialog that looks like this:


wicket:panel

   script type=text/javascript
   $.ui.dialog.defaults.bgiframe = true;
   $(function() {
   $(#summaryDialog).dialog({ draggable: true, resizable: 
false, autoOpen: false, height: 400, width: 800 }).toggle();

   });

   /script

   div id=summaryDialog title=Summary
   span wicket:id=label/span
   /div

/wicket:panel

and the java code is simply:

public class SummaryDialog extends Panel {

   Label label;
   ModelString labelModel = new ModelString();

   public SummaryDialog(String id) {
   super(id);
   label = new Label(label, labelModel);
   label.setVisible(false);
   label.setOutputMarkupId(true);
   label.setOutputMarkupPlaceholderTag(true);
   add(label);
   }

   public void displaySummary(String summary, AjaxRequestTarget target) {
   label.setVisible(true);
   labelModel.setObject(summary);
   target.addComponent(label);
   target.appendJavascript($(\#summaryDialog\).dialog('open');); 
   target.appendJavascript($(\#summaryDialog\).dialog('option', 
'title', ' + summary+  Summary'););


   }


It all works fine and I notice that at the bottom of the generated HTML, 
Jquery has added this to the DOM:


div aria-labelledby=ui-dialog-title-summaryDialog role=dialog 
tabindex=-1 class=ui-dialog ui-widget ui-widget-content 
ui-corner-all  ui-draggable style=overflow: hidden; display: none; 
position: absolute; z-index: 1000; outline-color: -moz-use-text-color; 
outline-style: none; outline-width: 0px;div style=-moz-user-select: 
none; unselectable=on class=ui-dialog-titlebar ui-widget-header 
ui-corner-all ui-helper-clearfixspan style=-moz-user-select: none; 
unselectable=on id=ui-dialog-title-summaryDialog 
class=ui-dialog-titleMy summary Summary/spana 
style=-moz-user-select: none; unselectable=on role=button 
class=ui-dialog-titlebar-close ui-corner-all href=#span 
style=-moz-user-select: none; unselectable=on class=ui-icon 
ui-icon-closethickclose/span/a/divdiv class=ui-dialog-content 
ui-widget-content id=summaryDialog


   span id=label1e2My Summary/span
/div/div

The problem is when I do something that updates the original panel in 
Ajax, it never removes the generated DOM so it results in two of these


div aria-labelledby id=summaryDialog
   span id=label1e2My Summary/span
/div/div
div aria-labelledby ... id=summaryDialog
   span id=label1e2My New Summary/span
/div/div

which causes it to no longer work since there are two elements with the 
same id in the generated DOM.


Has anyone encountered anything like this before? I could change my 
AjaxLinks to normal Link to perform a whole page refresh to get rid of 
jquery's generated DOM but I'd rather not if I could find a workaround.

using wicket ajax to add components containing javascript

2009-10-23 Thread Jason Novotny


Hi,

   I'm using AjaxLinks all over the place to refresh a container that 
contains custom components that themselves also use javascript. So what 
happens is  when I do target.add(myCustomComponent) that the javascript 
is not really in the page, its in the rendered markup so it often just 
doesn't work. Has anyone else had this problem or knows of a way to deal 
with it? Maybe I should put all the components javascript  as an include 
at the top, but I was hoping to keep it self-contained with the 
component itself for maximum reusability.

Have a look at this code, line #137 and #159

http://code.google.com/p/perfbench/source/browse/trunk/perfbench/wicket-jpa/src/main/java/wicketjpa/wicket/MainPage.java#137

In the HTML, use something like:

img id=spinner src=img/spinner.gif style=display:none/

You can also use an Image component and get the markupId generated by wicket
instead of hardcoding spinner etc.  Hope this helps.

ajax navigation toolbars not updating when rows are added to initially empty table

2009-08-22 Thread Jason Novotny

Hi,
  
   In a nutshell, I have a table that starts off empty and rows are 
added to it dynamically. So I have a DataTable inside of a 
WebMarkupContainer where setOutputMarkupId(true) and in the ajax 
callback I do a target.addComponent(markupContainer). So far so good and 
the table does update with new table rows. However, the paging toolbar 
on the bottom never gets displayed. So if I set the rowsPerPage to 3 and 
enter a 4th item, the row basically disappears. The code knows not to 
display a 4th row, but it doesn't display the navigation toolbar either. 
If I refresh the entire page, then the complete table with navigator 
suddenly appears.  It feels as if setOutputMarkupPlaceholderTag was 
never set to true deep in the bowels of the datatable/toolbar code since 
once it starts out as invisible it never has a chance to become visible. 
Does anyone have any ideas if this is a bug or I'm just missing 
something. FYI, I'm using wicket 1.4.0 just released.

div wicket:id=container
 h3a href=#span wicket:id=workoutCategoryBlah Blah
Blah/span/a/h3
   div wicket:id=activeGroup
    /div
/div

and use a RepeatingView rv = new RepeatingView(container);

This works fine except the resulting HTML still contains the outer div to
appear which causes the markup to break since it relies on Jquery to
attach
some classes, etc and is not expecting the outer div's.
I've tried rv.setRenderBody(false) which works for wicket Label's if you
don't want to display the span tag but doesn't work here. Does anyone
have
any idea of how to not display the RepeatingView markup of div tags?

Thanks a bunch. Jason

how to not display RepeaterView

2009-04-21 Thread Jason Novotny


Hi,

I have some markup I wish to repeat like so:

...

h3a href=#span wicket:id=workoutCategoryBlah Blah 
Blah/span/a/h3
  
div wicket:id=activeGroup

   p
   ol wicket:id=workoutList class=workoutList
   li wicket:id=itemspan 
wicket:id=labelstrongWorkout Name./strong/span/li

   /ol
   /p
/div


...

So I wrapped the whole thing inside a div wicket:id=container like so:

div wicket:id=container
   h3a href=#span wicket:id=workoutCategoryBlah Blah 
Blah/span/a/h3
  
   div wicket:id=activeGroup
    
   /div

/div

and use a RepeatingView rv = new RepeatingView(container);

changing style of ajax link

2009-04-17 Thread Jason Novotny


Hi,

I have code to create an ajax link and I want it to dynamically adjust 
its css class when clicked. This doesn't work since I don't think the 
onComponentTag is being called.


final AjaxLink link = new AjaxLink(navlink) {
   @Override
   public void onClick(AjaxRequestTarget target) {

 
   }


   public void onComponentTag(ComponentTag tag) {
   super.onComponentTag(tag);
   if (foo == 77) {
  tag.put(class, secondaryCurrent);
   }
   }

   };

Any help is greatly appreciated!

Thanks, Jason

how to display a BookmarkableLink so it can't be clicked

2009-03-30 Thread Jason Novotny


Hi,

I have a case where if some condition is met I don't want a link to be 
clickable... but I want it to display the link text (so overriding 
isVisible() is not an option). Any ideas on the most elegant approach?


Thanks, Jason

Re: using AutoCompleteTextField with wicket 1.4-rc1

I found my problem-- mootools javascript and wicket ajax components 
don't play nicely :-(
