getting an ActionMapping class from within a custom tag

[p <ll...@dowman.net>]

Hi,

What: I would like to find the roles associated with an ActionMapping 
from within a custom tag, but I only have the action name so I guess I 
need to get an instance of the ActionMapping class. How can I do this? 
How do I get an ActionMapping class, given the name of the action?

Why: I want a generalized way to hide links to actions that the 
currently logged-in user doesn't have access to. So what I plan to do 
is subclass the html:link tag-- my subclass will check the current 
user's access to the action for the specified link, and either hide it, 
or print only the link text.

Thanks in advance.

ModuleConfig mc = RequestUtils.getRequestModuleConfig (request);
ActionMapping am = (ActionMapping) mc.findActionConfig (actionName);

You can do it easier with tiles I think.
