Subject: Struts design question re: form action
I'm just curious
The standard DispatchAction can be a handy way to keep various tasks
together in the same Action, where they can share code, but without
getting into kludgy performs. Dispatch lets you have a separate perform
for each task, but all in the same Action, where they can be easier to
maintain.
You dont need two actions. You can use an 'action' parameter to decide which
action you are performing.
On your html:link add a parameter action=view
and on the submit action=add or action=edit depending on what you are
doing.
In your action, you can have if statements that perform different
In reference to having two actions (create and update) instead of one combined action,
this is exactly what I have done. While the struts-example uses a parameter, I
personally prefer not to take that route.
I have simplified my code/JSPs by having each do only one thing (good OO) at the

There are a number of ways to achieve this, and again (!) it's about choice, although
I must say this can be confusing for newbie (and experienced!) struts users.
1. 2 Actions, 1 for 'pre' and 1 for 'post' processing
2. An 'action' parameter, with switch behaviour in the action class
3.

But my beans already contain the validation! Besides, performing the
validation in the ActionForm is effectively tying business logic (data
validation) to the web framework dontya think?
Well, I put data type and required field validation only in the bean.

i believe that you could subclass ActionServlet and implement the
processPreprocess method. this is called before processActionForm and
processPopulate.

Yes you can do the add/edit all on the same form. If have a database
generated code or key you can put that in a hidden field. When in the
action examine the form or request obj to see if that key is there, if it is
you have a modify, if not add the record.
Have you page that lists the songs
Why do Action, ActionForm and ActionMappings classes keep references
to the ActionServlet?
So that they can access the many features available through the
servlet, like logging and (lately) a JBDC DataSource.
The ActionServlet is like a switchboard, and the references a way they
can dial "0"
