how debug jsf/j2ee web application

to debug jsf application or a j2ee web application, you can set PROJECT_STAGE context parameter to Developement like this (in the web.xml file):
<context-param>
<param-name>javax.faces.PROJECT_STAGE</param-name>
<param-value>Development</param-value>
</context-param>


you can turn this parameter to Production to stop debug. 

[Problème] 404 - Component not found (joomla 3 back office)

This article is for joomla components / modules developers.
Usually you have this error when trying to run/configure your joomla 2.5 component on joomla 3.x plateform.
This error is due to non 100% compatibility of 2.5 components with joomla 3.x
For some simple components proceed as follows :

1. In every file that references DS variable
   put at the begin :
   if(!defined('DS')) define('DS', DIRECTORY_SEPARATOR);
2. rename admin.your_component.php file in admin section to your_component.php
3. Change each JController or JView classes reference to JControllerLegacy or JViewLegacy
4. Don't forget to do that to the 2 sections site and admin

Jquery ready function and problems with media queries

yesterday i have faced a problem
i had  to make a design responsive according to a psd
i've found that some blocks that were injected by jquery thanks to

$(".yourdiv").append(.....)

jQuery(function(){

if($window.width()<768)

{

     $("#mydiv").appendTo("#block1");

}else{

         $("#mydiv").appendTo("#block2");

}

}

and mydiv had two styles

@media screen and (max-width: 767px){

    #mydiv STYLE1

}

@media screen and (min-width: 768px){

    #mydiv STYLE2

}

i found that mydiv had the style 2 and was the child of block 1 which is incorrect for me

finally it was wrong to use jQuery(function(){} which fires before application of media queries
i've used modernizr library
with this hack

(function($){

    function doneResizing() {

        if(Modernizr.mq('screen and (max-width:767px)')) {
                     $("#mydiv").appendTo("#block1");
        }

        else if(Modernizr.mq('screen and (min-width:768px)')) {
                                  $("#mydiv").appendTo("#block2"); 
        }

    }

    var id;
    $(window).resize(function() {
        clearTimeout(id);
        id = setTimeout(doneResizing, 0);
    });

    doneResizing();
})(jQuery);

 

that's all

Prestashop déclaration de variable globale de configuration (Module FB/Twitter pour prestashop)

Lors de la création d'un module spécifique sous presta, nous avons souvent besoin de stocker quelques variables dans la base de données du système.
Dans le cas ou la variable est simple et que l'utilisation d'un CRUD  n'est pas aussi nécessaire, l'utilisation d'une variable système peut suffire, on parle d'une variable de configuration.
Comment la créer ?
c'est simple le fait de mettre à jour une variable de configuration qui n'existe pas la crée et lui affecte la valeur indiquée.

Configuration::updateValue('MA_VARIABLE',"");
On met ça dans la fonction installe de notre module si vous voulez.

Comment la lire?
c'est simple aussi
Configuration::get("MA_VARIABLE") retourne la variable

Dans ce qui suit, j'ai crée un petit exemple qui illustre ce comportement:
Un module qui affiche' 2 icones (fb+twitter) dont les adresses sont configurables depuis le back-office
