I disagree. I think that a filter is best suited for what you are trying
to accomplish. Whenever a request is submitted to your application, you
should verify that the user is valid before anything else takes place. As
such, a filter meets that requirement (among other things).
In addition, implementing a filter doesn't negate any work done in struts.
On the contrary, in my opinion, it enhances application.

Another option is to throw a "session expired" specific exception (from
the filter) and manage it in your container.
Of course (as mentioned in another post) you can also use
response.sendRedirect("/path/to/your/action/")
Hope this helps.
