Description

When I start my Struts2 app I see this warning :

22:30:33  WARN [com.opensymphony.xwork2.config.providers.XmlConfigurationProvider.buildResults] - No default parameter defined for result [json] of type [org.apache.struts2.json.JSONResult]

I can't find any information about that in the documentation.

What am I doing wrong in my struts config file ?

In my app I use configuration by annotation and by xml.
