apologies as i thought you were uptodate on the latest version
i assume you are implementing
public ActionForward execute(ActionMapping mapping,
ActionForm form,
ServletRequest request,
ServletResponse response)
throws Exception;
the ActionMapping mapping will call findForward which will
Return an appropriate ActionForward object that identifies the presentation
page to be used to generate this response, based on the newly updated beans.
Typically, you will acquire a reference to such an object by calling
findForward on either the ActionMapping object you received (if you are using a
logical name local to this mapping), or on the controller servlet itself (if
you are using a logical name global to the application).
its important to declare local variables in Action specifically:
controller servlet creates only one instance of your Action class, and uses
this one instance to service all requests. Thus, you need to write thread-safe
Action classes. Follow the same guidelines you would use to write thread-safe
Servlets.
Only Use Local Variables - The most important principle that aids in
thread-safe coding is to use only local variables, not instance variables , in
your Action class. Local variables are created on a stack that is assigned (by
your JVM) to each request thread, so there is no need to worry about sharing
them. An Action can be factored into several local methods, so long as all
variables needed are passed as method parameters. This assures thread safety,
as the JVM handles such variables internally using the call stack which is
associated with a single Thread.
For each request made of the controller, the method process(HttpServletRequest,
HttpServletResponse) will be called.
so keep the guts of the request processing in the Action process method
http://struts.apache.org/1.x/userGuide/building_controller.html
ActionMapping considerations:
use RequestActionMapping instead of SessionActionMapping
