As a convention, I'd suggest using some other prefix entirely for the
path-helper servlet, like /ex/*, so that it would plug-into any
application that might already be using *.do or /do/*, but, yes, I think
this seems like the cleanest solution. It avoids major surgery on the
existing action-mapping path matching, it can plug-into any existing
Struts application.
Do the applications using extra-path-information also need the
parameters changed to include a paramId, or can you just pass whatever
is between the slashes? From what you are saying, it sounds like you
need the capability to do both, since an existing application might be
depending on the position of the parameters as an implicit Id?
If we did *not* need to generate an id for the parameter (we can pass
?param as-is instead of {id}=param), we might be able to use a heuristic
search, and avoid a second config.

Unfortunately, I don't have one of this of my own, and don't know how
things are usually done.
