ActionForms and errors?
Hello,
I am trying to figure out how ActionForm and validate()-function work. If I
returns an error (ActionErrors) from my ActionForm it fail (se below for
output). Returning null everything works fine. I thought that when returning
an error I would return to my loginpage automatically. But I dont. Anyone
who can explain to me hwo this works og give me a link with a fully
functioning example? I have looked at examples but they are for the most
parts of an example.

One way to solve such a problem is what I proposed
the so called Action Controller Delegation Model.
When you *find* the target action mapping according
to an action path, you invoke the execute method on
the action class directly. So the action path of the
target action mapping could become a configurable
parameter in your current action mapping in such model.

Also important is if you have a different form, the
properties will be populated according to the old
submitted parameters.

Re: Action forward to another action without form
Posted by Jing Zhou <ji...@netspread.com>.
Forwarding to a target action is not considered as a
good practice in the past is because the form bean population
and validation machineries will be invoked again when
Struts process the action (and some more reasons).
Of course, if there is no form bean specified in the target
action mapping, it makes sense in such cases.
In many use cases, I find people really need
*shared* action controllers in their business requirements.
The best way to have the functionality is to develop
your own action controller delegation model. In such
a model, you *find* the target action the same way as
Struts *find* it. It is a very simple solution and you
could avoid the form bean populations and validations.

you can define it to your forward in your struts-config, instead of
forwarding
it to a page, forward it to an action. but this is not a good practice
though.

Re: Action forward to another action without form

just have your forward in the action go to something
the servlet will pick up
<forward name="success" path="/AnotherAction.do"/>
and just
mapping.findForward("success");
Note that this may not be syntatically correct...
