And speaking of new solutions, it's worth pointing out that in Struts
1.3 you can use the commons-chain API to execute a chain of Commands
instead of or in addition to an action. If you used a chain instead
of an action, you could use the commons-chain Filter interface to
have reusable code operate before and after just the action execution
stage.
Note that the complete chain is executed before the action, so you
couldn't use this around an Action, per se. It wouldn't be that hard
to move your action into a chain by implementing Command, but I'll
spare the details...
And, with WebWork, which is becoming the basis of Struts 2, you can
apply a stack of interceptors on a per-action basis, which is another
way to reuse common code in processing requests.

You can certainly use servlet filters with Struts. It would be hard
to apply a filter to a specific action, since the filters operate
before-and-after Struts but not during the execution. I suppose you
might have the filter set a request attribute and then have an Action
look for it, but that seems tangled and suboptimal.
I suppose in the end it depends on what you're trying to do.
