I have a problem with struts 2 action tag on GAE. When I try
<s:action name="User_info" namespace="/" executeResult="true" />
i get following error
"com.opensymphony.xwork2.util.logging.commons.CommonsLogger error: Could not execute action: //User_info java.lang.IllegalArgumentException:"
On local everything works fine... Thanks
The problem was within the action itself not in the Struts 2. I used JDO but forgot to include jar fiels in lib folder. My mistake, Sorry.
