Another solution is what I did, was to specify a servlet as the value of the
input attribute in struts-config.xml, and then in the servlet I have code
which dynamically determines the correct URL for input and does a forward
to that URL.

You will have to parameterize the action of your html:form then have

Subject: Modifying action input at runtime
Hi all,
I am looking to use an action to handle the submission of multiple
similar forms. Normally I would use separate actions, but in this case
the code is identical for the different forms. Everythign seesm to be
working fine except for the specification fo the input parameter on the
action. Depending on where the request cam eform, I want to have the
validate method return to different places. I thought the easiest way
to do this would be to use mapping.setInput() to specify at runtime
where I want it to return to, but when I try to do this I am getting
Servlet Error: Configuration is frozen: java.lang.IllegalStateException:
Configuration is frozen
You may be wondering how the same Form class could validate a bunch of
different html forms effectively. I actually have different Form
classes for each of the html forms, but in order to trick the
struts-config into allowing me to specify them all for the single
action, I specify a common Form base class in struts-config. Now I want
to dynamically set the input parameter in the validate() method of the
BaseForm subclass - but I can't see an obvious way to do it if the
configuration is frozen. Is there any way around this problem?
