Why ActionProxy is used
Hi all ,
this might be a trivial question and I hope this is the right place
to raise my question.
Why do stuts2 implementers use ActionProxy. What is the purpose of the
this class.
I have read the description given in the core developer guide.Yet I
didn't get the idea.I appreciate if somebody can simplify the idea of
ActionProxy.
Thanks & Regards,
Nuwan Arambage

Via a Factory:

Look for config.getContainer().getInstance(ActionProxyFactory.class).createActionProxy(...

ActionProxy is decorating
(http://en.wikipedia.org/wiki/Decorator_pattern) the Action class you
currently write by executing the interceptor stack defined by
configuration in struts.xml.
