Struts: authenticating next action

Hi,

I'm writing a simple web application, where a user can perform several
actions from a single page. I know the user has one of the required roles
for the current page; Struts (I use version 1.1) makes sure of that.

However, I also want to determine if a user may go to the page my Action
implementation refers to. The forward used for this is tied to the name of
the action supplied by the ActionForm.

So far, I think I should do the following:
1 Find the ActionForward that will be used if the action is executed
2 Find the URL the ActionForward refers to
3 Find the ModuleConfig for the new URL
4 Find the ActionMapping for the new URL using its ModuleConfig
5 Check if the user has one of the required roles for this ActionMapping

Is this a good aproach?
If so: how do I do steps 2&3 when using Struts modules?
Is there a better approach?

Any help will be greatly appreciated.
