output xml file

[Wu, Ying (LNG-CIS)]

I need to send a string which represents a xml file to browser, I need to
call response.setContentType("text/xml").  But it is at ActionServlet level
and is default to "text/html".

1. Any idea?
2. I can do the output at MyAction.perform(, request, response, ) level, but
how to handle the return type of this method?

Thanks.

Ying
