Re: Is Action Instantiated Once?

How did you code the Action ?

clicks on the next button will not display anything until the screen of the
guy who clicks later finishes.

Subject: Is Action Instantiated Once?
Hi folks,

I have a address book page that has the previous and next buttons.  I
     

notice if 2 different users try to access the address books, last one who
clicks on the button always get what it should display.  This sounds very
like they are both are using the same Action.
 

The address book action extends a ActionBase that extends Strut's
Action.  Would anybody tell me if Strut will instantiates a new acton
everytime it is called?
     

No ... one instance only (just like servlets).

   

Did I miss something on the configuration to
make it thread dependent?
     

You're probably using instance variables in the Action class to store
things relevant only to a particular request.  If so, use local variables
or request/session scope attributes instead.
   

Thanks!
