[xwiki-users] how to generate XML from a velocity script page ?

Hello everybody, i need to use Ajax but i can not generate XML from a velocity script page. Here is a piece of my script : {{velocity}} $response.setContentType('application/xml') #set ($out = $response.getOutputStream()) $out.write("<?xml version='1.0' encoding='ISO-8859-1'?><test>test</test>") ... {{/velocity}} But my responseXML is null. I suppose that it's not the good way to generate XML from velocity. Thanks for your help. M. Canzerini
