-----------------------------------

I'm not sure, do you want to reuse actions or ActionMappers ?

> The PrefixBasedActionMapper is able to map different actions to different mappers using prefixes. So you can have something like this:
> /preffix1:mapper1,/preffix2:mapper2,:defaultMapper
> And the following URIs would be processed by different mappers
> /preffix1/mynamespace1/myaction1 (by mapper1)
> /preffix2/mynamespace1/myaction1 (by mapper2)
> /mynamespace1/myaction1  (by defaultMapper)
> So you can have three different ActionMappers, one per prefix. The problem with this is that you can not reuse the same actions for different prefixes(ie, reuse an ActionMapper), since the ActionMapper will try to match the full URI, without taking out the prefix. I suggest to parametrize the PrefixBasedActionMapper to remove the preffix from the URI when calling the ActionMapper, so the same mapper can be used more than once.
