In the current API 1.1 beta3 which has changed.
I have an Action `Preloader' but I what to create or get another a reference
to Action `Activate'. What is the best way to do this.
public class Preloader extends DispatchAction {
public void execute( ... ) {
ActionServlet servlet = getServlet();
RequestProcessor processor = servlet.getRequestProcessor();
Action activateAction = processor.createActionCreate();
}
}
Unfortunately the `ActionServlet.getRequestProcessor' call is protected.
What I was to do is prepopulate the action form that is
associated with `Activate' action mapping ?
ActivateForm = magic_api.getActionForm( "/activate" );
activateForm.setSymbol("alpha");
Then I can dispatch forward to the activate mapping.
This is sort of like action chaining but difference.
Any ideas on the new best practice?

At work I couldn't remember for the life of me how I did this before.
I got legacy code at home that shows how to pass settings to
a second action.
The answer was to define a local forward in the `Preloader'
action with the path of the next second action `Activate'
<action path="/preloader" name="preloaderForm"
scope="session"
validate="false" >
...
<forward name="processSelect" path="/activate?action=processData" />
...
<parameter name="action" />
</action>
<action path="/activate" name="activateForm"
scope="session"
validate="false" >
...
<parameter name="action" />
</action>
In the `Preloader.processSelect()' you set any parameters in the request scope
class Preloader extends Action
ActionForward processSelect(...) {
request.setAttribute("firstName", "Michael" );
request.setAttribute("lastName", "Jackson" );
return mapping.findForward("processSelect" )
}
}
In the `Activate.processData' retrieve the values from the request scope and
set the them yourself in the action form.
class Activate extends Action
ActionForward processSelect(...) {
form.setFirstName( request.setAttribute("firstName"));
form.setLastName( request.setAttribute("lastName"));
return mapping.findForward("processSelect" )
}
}
Now I have wait until I go back to work tomorrow. !Bastardo!
Ah, the trials and tribulations of consulting.
Craig's idea of chaining of responsiblity pattern for Struts Action is needed
right here and right now.
I would still like to know how to retreve a list of a web application
`Actions' object from inside `Action.execute()' call. Any ideas?
