This method will cause an actual redirect, and so, the user will see the
correct name of the action in the address bar.
But it IS a bad idea to be showing the url of the webpage. If you can,
you want to use only action URLs, because in ur action bean you can
check if u have ur variables set up correctly etc etc, which being unset
would cause mayhem on a webopage.
Also its supposed to reset the request variables, but I have not yet
faced a problem. I hardly save any variables in the session scope --
most of the times, i save my objects in the request scope only.
Also, instead of using ActionErrors, a more elegant approach is to
forward to the same action which calls the form-bean, for example:
<action path="/main"
type="okay.beans.MainAction">
<forward name="success" path="/main.ftl"/>
</action>
<action path="/adduser"
input="/main.ftl"
type="okay.beans.UsersAction"
name="usersForm"
validate="true"
scope="request">
<forward name="error" path="/main.do" redirect="true"/>
<forward name="success" path="/next.do"/>
</action>
So everytime I forward to main.do, I can display my webpage which is
main.ftl (freemarker), which actually the user does not know even
exists. And after performing the requested action, I can either display
my form again (in case of an error) or move on.
Someone, plz correct me if im wrong.

In either case, how could you specify to Struts to construct a
ForwardConfig
object with redirect=true??
Either nested within an <action> element, or in <global-forwards>,
simply use:
<forward name="foo" path="/bar" redirect="true" />

Thanks,

I looked at the source of the RequestProcessor.processValidate()
method, and it certainly doesn't look like there's any way to
redirect on validation error without modifying the behavior there.
I think that if in your <controller> element in Struts config, you use:
<set-property property="inputForward" value="true" />
then Struts will do a "mapping.findForward(input)" upon validation
failure. This forward could be defined with "redirect='true'"
That doesn't help with getting the errors stored in session scope
instead of request scope, though.
