   For step 1:
Don't print
 the JSON directly. You'll have escaping
 issues. In order to ensure the generated JSON
 is valid you should
 build the JSON in memory
 (using Velocity/Java maps, arrays and basic
 types) and then serialize it:

 $jsontool.serialize({
   "greeting": "Hello",
   "location": "World"
 })  
 I agree but one* purpose was to use  Vincent example on
 this page: http://extensions.xwiki.org/xwiki/bin/view/Extension/Output+JSON
 Perhaps we (who?) need to modify both pages? 
Anyway, do you prefer this code?

{{velocity wiki="false"}}
## If AJAX call
#if("$!request.outputSyntax" != '')
  $response.setContentType('application/json')
#end
#set($MyJsonData = {'greeting': 'Hello', 'location':
'World'})
$jsontool.serialize($MyJsonData)

{{/velocity}}

...

 For step 4:
 Don't hard-code the page URL and use the 'get'
 action
 instead of 'view' to avoid
 adding view statistics entries.

 var url = new
 XWiki.Document('JsonHello',
 'Sandbox').getURL('get');  
 Thxs I was too lazy to take too long time to find JS
 function. :-)

 Also, to avoid the need to
 URL-encode the request parameters you
 should
 pass them using an object not a string.

 var params = {

 'xpage': 'plain',

 'outputSyntax': 'plain'
 };
 $.get(url, params,
 function(data) {
   ...
 });  
 Yes thxs you
 => I uploaded/update my page

 (The worst is that I hate JS) :-)

 Hope this
 helps,
