What's the point then of having an action, if the

Because interceptors are normally called for *groups*
of actions, not just one... just like it says in the
first couple of paragraphs at the top of:
http://struts.apache.org/2.x/docs/interceptors.html
For instance, "validation" is a cross-cutting concern.
So it makes sense to move it away from the code that
decides what to to with the validated data.
GOTCHA, so if I have a common method in all the action and I need to
execute some code that is generic to all of them, then makes scenes to
put in an interceptor. coooooool.
Ok, another question. If I have an custom interceptor does this sop
another interceptor from execution. For example, I have this code:
public String intercept(ActionInvocation invocation) throws Exception {
AccountAction action = (AccountAction)invocation.getAction();
return action.execute();
}
shouldn't the interceptor that's responsible for setting the values on
the action, gets executed too ?
in my case it's not. Why? here' my config:
<action name="accountAction" class="billing.AccountAction" >
<interceptor-ref name="prepareAccount"></interceptor-ref>
<result name="SUCCESS">/pages/accountView.jsp</result>
<result name="ERROR">/pages/exception.jsp</result>
<result name="input">/pages/accountView.jsp</result>
</action>
Of course you *could* put all your action code into an
interceptor and define an interceptor stack for every
action-that-no-longer-had-an-action. There are many
ways to make things harder--don't get me wrong, I
applaud your efforts to find them.
I am trying to make things easier :P but definitely always interested in
finding a harder way :P
You could put all your action code into filters, then
you wouldn't even need servlets. Or put everything
inside a JSP, then you wouldn't even need to compile
or worry about whether or not your container
hot-deploys.
This will be a great idea. But then I will never be using struts. You
know, it has to be used in a away or another. Someone must use it. It's
unfair for the opensource community to write softwares and no one uses
them. :P lol
