Yes you can because you access input, output, block in the JSP
using the custom tags. Because an expresso controller writes a controller
response object to the request scope. The input value can also read back a
controller requests.
But I do not why you cannot reuse old ActionForm that you have already written,
though. The expresso controller does not expose the action form bean
as you and I know in the "actionPerformed" method. On the otherhand
you gain automatically action command dispatch handling.
It was / is issue for the lead developer. The bone of contention
being transplanting an old Struts example into an Expresso one. It should
be made easier or as easy as possible. I would Expresso 4.0 is still new,
and these issues dont get played until someone try to build
an application with the intention of going __live__.

Subject: Re: Advice needed on Stuts versus Struts/Expresso
what do you use instead of ActionForm when using expresso/struts?
when doing expresso/struts do you still use Input/Output/Block/etc objects?
