Using Java (preferred solution)

built some SOAP services but providing a REST interface (just servlets) and need a way to use regex to parse out the urls.  the basic pattern is

get all things:
http://blahblah/things
get all things with some criteria
http://blahblah/things?id=value1&type=value2

getcertain things by name
http://blahblah/things/name

the regex pattern i was using seems to always give me the things/name and i really want an easy way to say
things
things?...
things/

but not things/something
which may or may not have parameters

I am looking to validate parameters once i know which operation i want to deal with.  the idea of the above url pattern was that some parameters are required or not allowed for some of the patterns so i don't want the regex to care about the parameter but can't use $ (end of line) b/c parameters might be presenent

i kept trying "things[/]?" and other permutations

jonasmit,

Maybe I am oversimplifying this or misunderstanding something but what about ...

things$|things\?|things/

To use it in Java you will probably need to add some slashes.  Let me know if you have a question using it.  That expression will give you what you want if I understood you correctly.

Let me know if you have any questions or need more information.
