  I am undestanding this now.

  I have some pages on my system who can be called
from different
places. The local from where they was called will
determine the next
page to show.
  One example of this is the login action. It can be
called when the
user press the "login" link on a application page. On
this case after
the login is finished the next page show is the main
site page.
  But when it is called to authenticate the user who
is doing the
checkout the page to be show is another.
  What is the best practice to handle this type of
problem ?

  Can you show how to do this ? Some small code is ok.

  I was able to implement what I want using this idea.
But the code is
very bad. I really hope there are a better option.

A simple way to do it :
you should define 2 actionMapping
first one for "login", second one for "checkout"
the two use your LoginAction class and forward to success
"success" = Menu.sjp on mapping 1
"success" = Other on mapping 2

A second way to do it:
add a hidden input on your form (let's call it "dispatch"). This is a
very common way to
have different behaviour from the same action.
then define 2 forwards :
"login" => Menu.jsp
"checkout" => Other.jsp
in LoginAction, use dispatch value to get successful ActionForward.


For such a case you don't need to "forward parameter" to another
action. Your action just need to know in which case it is used (using
2 mappings or based on a form input)
