Action Instantiation
This may be a Struts 101 question. But, when a request comes through the
ActionServlet and is forwarded to an Action class.... how are the Action
classes instantiated. Is a new Action class instantiated for each request or
is an Action class instantiated once and reused for all requests?

Ya, sometimes I just can't decide which board to post to. But, thanks I
appreciate the info and the link. I just wanted to make sure that the
ValidatorLookupDispatchAction I submitted as an enhancement was properly
coded and thread safe. And.... it is. Thanks Ted.. "YOU DA MAN!" ;-)

The best place to ask anything that might be a Struts 101 question is
the Struts USER list.
http://jakarta.apache.org/struts/doc-1.0.2/userGuide/building_controller.htm
l#action_classes
"* The controller servlet creates only one instance of your Action
class, and uses it for all requests. Thus, you need to code your Action
class so that it operates correctly in a multi-threaded environment,
just as you must code a servlet's service() method safely."
In Struts 1.0, all Actions are instantiated lazily. In Struts 1.1,
Actions with a PlugIn interfaces are instantiated at startup.
