[REPOST] Get Raw Action Path.
I have an Action defined as:
<action
path="/myaction/**"
type="...MyAction"/>
Within the Action class itself I want to get at the path attribute as
defined in the config file, i.e.
/myaction/**.
I can get the requested path, for example /myaction/somepath/xxx.do via
actionMapping.getPath() but not the original path to which the action was
mapped. Is there any way I can get at this?
Thanks in advance.

Cheers for that David. Despite all my searching through the Struts
source I couldn't figure that one out.
Luckily I'm not using modules so that should work a treat.
Thanks again,
Alan.

A solution in Struts v1.2.4 is at hand, too bad it's not some quick method
call like getPattern(). If you can figure out what I did, you can use it.
:) Seriously, I obtained a raw list of Action Mappings (unprocessed paths,
as in Struts config files), then I used a Struts util class WildCardHelper
to match the patterns, and viola!
WARNING: Since my webapp has only one struts config file, I haven't tested
this code with Modules. If it doesn't work and you have modules, you'll
have to figure out how to check the ActionConfig's in each module's
ModuleConfig (and how to get each modules ModuleConfig).

Thanks for the pointer. I've been looking through the RequestProcessor
source without any luck so far. Maybe I'll stumble across it soon.

I don't know the specific answer to your question, but I learned a lot
by writing a method that prints out the key and value for every
attribute in every scope, and calling that method at various points
along the RequestProcessor timeline (by overriding various methods of
RequestProcessor). RequestProcessor invokes a dozen or so methods on
itself for every request, and during that time many attributes are set
and/or removed from various scopes.
I do recall that the controller Servlet mapping was available. Not sure
about specific Action mappings.
