Hello, all,
I am not sure whether it is a good practice to:
eliminate instance variables from Struts action class; and
make all methods static.
Basically it turns the action class into a utility class.
Any comments? Thanks.

Hello, all,
I have the following problem:
In ActionA{
ActionErrors errors = new ActionErrors();
errors.add( ActionErrors.GLOBAL_ERROR, new ActionError(
Afailed ) );
saveErrors( request, errors );
}
In ActionB{
be the only
reason the next error was caused )
if you are using the validate() method. you can achieve this by simply
adding new errors prior to returning.

Use this inside the execute.
ActionErrors errors = getErrors(request);

Hello, all,
I am not sure how Struts matches with the j2ee presentation tier design
patterns.
For example, I assume:
Decorating filter: N/A
Front Controller: ActionServlet
Composite View: taglib template
View Helper: Action, ActionForm
Dispather View: N/A
Service to Worker: ActionServlet,
A newbie question:
Currently I have
nested:write property='width'/
nested:write property='depth'/
I want to calculate the area IN JSP (not to modify ActionForm) as width X
depth.
I suppose I am going to use scriptlet. How to achieve this?
Thanks.

thanks for your reply. the powerful if...else can absolutely solve the
problem, but the architect doesn't allow me to do so. JSTL is not used

Any calls to request.getParameter(operation) should return null after

One more thing...
Why is the ActionForm using type ScheduleVO instead of ScheduleBean? You may
want to try returning ScheduleBean.

Hello,
Sorry to send the question again. But I didn't see the message appearing on
the mailing list for some reasons. Besides the previous message has a wrong
return email address.
I have an ActionForm, which includes a field/getter/setter of subclass. The
subclass inherits the description

public void setDescription(String description) {

Subject: does ActionForm
Hello,
Suppose I have ActionForm aForm, which has a private field aBean. aBean is
a dumb data hold class with a field aData. I can populate the aData from my
backend data resources and write it to JSP as the following:
nested:form action='the action related the aForm'
nested:nest
you right, but you surely can access a nested bean in
a form.
i.e.:
html:text name=aForm property=aBean.aData /
...is that understandable?
(Do you have a nested taglib?)
