["Wes Wannemacher (JIRA)" <ji...@apache.org>]

Wes Wannemacher commented on WW-2815:
-------------------------------------

Lukasz,

XStream is what we use for the xml result type... However, we don't really expose any mechanism for massaging the output that XStream generates... To get an idea of what he's talking about, you can read a little bit here - 

http://xstream.codehaus.org/alias-tutorial.html

I know that when I've used xstream for marshalling/unmarshalling in a Spring app, I had some properties I could set to get rid of some of the superfluous XML tags (like <list>...</list>). I would agree that we should try to make this a bit more flexible, but I think it's fine to push it until 2.2.x. I'm leaving this comment so that anyone who wants to work on it (since I haven't had much time lately) will have a starting point.

> XStream best feature is the way to configure the output but there is no way to control the engine other than extending current XSTream handler. It should be easier. An XStream engine is also created for each request, could it be optimized?
