What I don't understand is I have an object who's constructor needs
session data...
So it calls:
Map session = ActionContext.getContext().getSession();
But session is always null...
http://struts.apache.org/2.1.8.1/struts2-core/apidocs/com/opensymphony/xwork2/ActionContext.html#getContext()
Explains that this static method works by looking up the value in a
ThreadLocal: "Returns the ActionContext specific to the current thread."
So if that constructor is happening within the same thread in which the
request was originally being processed, and after xwork finishes setting
up that context, it should work:
"The ActionContext is thread local which means that values stored in the
ActionContext are unique per thread. See the ThreadLocal class for more
information."
But random code in a random thread occurring at a random time cannot
rely on ActionContext.getContext().
I'd check out the *Aware interfaces if I were you.
