passing param as part of URL path

[Brian Lalor <bl...@bravo5.org>]

I'm working on a product catalog display application that uses the  
same logic and code, but takes a common parameter for *every  
request*, specifying the specific catalog to use.  The application is  
a web service of sorts, and has no state stored between requests.

I would like to use URLs of this schema and embed the catalog param  
in the path:
     http://host/root/CATALOG1/action.do
     http://host/root/CATALOG2/action.do

I prefer this idea to specifying a request parameter (?catalog=1) for  
every action.

I was thinking that I would somehow capture CATALOG1 and CATALOG2 and  
stick them into the request, but I'm not sure how to go about it.  It  
this functionality that Struts already has, do I need to implement a  
filter, or should I subclass the main ActionServlet?

Thanks in advance,
B

You can do this using wildcard action mapping paths:
