Re: [Struts2] session variable empty in the JSP
I have tried but it did not help.
I have tried also by defining the action as a bean and populating the
context bean in the Spring configuration file (with the Struts Spring
plugin).
But the same error comes.
I guess I will pursue with my solution of redirecting to another action on
the first call.
Thanks,
Samuel

[Struts2] session variable empty in the JSP
Hi,
I faced few days ago a problem with the session variable in the JSP. I
posted the problem here but did not get any solution:
http://stackoverflow.com/questions/9381991/session-variable-empty-in-the-jsp-on-first-access-in-a-struts2-spring-applicatio
Perhaps some of you have an idea.
Basically the session variable in the JSP is empty on the first call to my
action (when the session gets initialized).
That means that my JSP fails to retrieve any information from the session
in the Struts tags on the first display.
From the second call it is OK.
I have checked that the session is correctly initialized in the JSP. The
problem comes only with the session variable in the struts tags.
%
System.out.println(((my.bean.SessionBean)session.getAttribute(context)).getProfiles());
% = OK
s:property value=%{#session}/ = KO (empty)
${session} = KO
I solved it by adding an additional redirectAction on the first access
(when I detect that it is a new session).
But I wonder why I get such a problem, which I never had before.
Thanks,
Samuel
Re: [Struts2] session variable empty in the JSP
Post the code in which you actually set the attribute in the session scope.
