Hi,
sorry for too fast response,
i see that it is implementing it,
another thing to notice is that
in action You have access to session field which is a map constructed
by struts, not real session object - as far as i remember.
In jsp you can do < s:property value="session.get('variable')" > to
show key from session in jsp.Hope that it will help, Pawel Wielgus. 2010/1/6, Sergio <killing-is-my-busin...@hotmail.com>: > Paweł Wielgus escribió: >> Hi Sergio, >> add SessionAware interface to your action. >> >> Best greetings, >> Pawel Wielgus. >> >> 2010/1/5, Sergio <killing-is-my-busin...@hotmail.com>: >> >>> Sergio escribió: >>> >>>> Hi people, >>>> >>>> i'm a newbie to struts2.
