Hi, Sergiu Dumitriu I tried your way like this: {{velocity output='false'}} $response.setContentType('application/xml') #set ($out = $response.getOutputStream()) #set ($s = "<?xml version='1.0' encoding='ISO-8859-1'?><test>test done</test>") $out.write($s.getBytes('ISO-8859-1')) {{/velocity}} But this still has the same parsing error: XML Parsing Error: no element found Location: http://localhost:8080/xwikim/bin/get/Geo/hellotest?outputSyntax=plain Line Number 1, Column 1: ^ I tried both from the ajax call and the link: http://localhost:8080/xwikim/bin/get/Main/hellotest?outputSyntax=plain and I got the same error. Any more clue?

Thanks for your help.
