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.

There is no #write(String) method in OutputStream but ServletOutputStream (which extends it and which is what you get in standard XWiki) provide a #print(String) method. but there is another issue. If you do only that XWiki will still send all the UI after your actual XML content so your XML parser will not like that too much. To avoid that you can use $xcontext.setFinished(true) so your script should looks like: {{velocity}} $response.setContentType('application/xml') #set ($out = $response.getOutputStream()) $out.print("<?xml version='1.0' encoding='ISO-8859-1'?><test>test</test>") ... $xcontext.setFinished(true) {{/velocity}}

Thanks for your help.

See this other thread: http://markmail.org/message/tjrnj6zy2n37blua

Short summary, you should call flush() and close() on the stream after you're done writing data to it.

You can indeed also use $out.flush() and $out.close() instead of $xcontext.setFinished(true).
