thanks for this idea; I implemented it the way you suggested - with this
solution everything is still configurable through the struts-config file
as you are stating below ...
thanks a lot,
karin.

I am new to Struts and would appreciate your ideas for a solution to
the following problem:
In my webapplication I have a login-form with a submit and cancel
button. When the user clicks the cancel-button I would like to return
him to the page he previously visited (before calling the page with
the login-form). Using a forward in the action-mapping would redirect
the user always to the same page (e.g. welcome.do), therefore I was
thinking of storing the last visited page in the session and use it
for a redirect, but then I would bypass the struts-config ... what do
you think? Is there a possibility to achieve this in Struts?
The second option is the one you want. There's no way you can
statically define a forward in struts-config that points to 'the page
the user was on before this one'.
What you could do, though, is create a ReturnToPreviousPage action
which redirects to the URL you stored in the session and have an
action forward in struts-config pointing to that action. You still
have to keep track of where that action should redirect to yourself
(though the session or whatever). The advantage is that your
struts-config is still declaratively declaring the behaviour -- and
you can then change the behaviour (e.g. to always forward to the
application home page instead of the previous page) by modifying the
config. You also get the option to re-use the ReturnToPreviousPage
action anywhere else you need the same behaviour.
HTH,
