It's funny that you happened to ask this tonight, I am working on a JSON
result with annotations as I am writing this...
First off, are you using a plugin to provide the annotations? If so,
which one. I am using struts-2.1.3-snapshot (which might make a
difference) in conjunction with the conventions plugin.
I have an action with the following annotation and it is working fine
for me -
@Action([EMAIL PROTECTED](name="success",type="json")})
