Optional parameter in @PathParam annotation

We are facing issue related with making a path parameter optional.

original URL /expire/{token}

What we are trying to do is have the same service work for the URL's below.

   1. /expire/{token}
   2. /expire

Ex:- @Path("/expire/{token}")

We have already applied other solutions from SO,but no luck so far.

We can use regular expressions,

"@Path("/add/{a:([0-9.]*)}/{b:([0-9.]*)}{p:/?}{c:([0-9.]*)}")"

here path can be 

add/2/3
add/2/3/4

my case I am using regular expressions for allowing only numbers

Logically, it doesn't seem to make sense to have it optional. Your URI should handle the type of request it's supposed to do. But, I came across a post to make the @PathParam to be optional with a small hack using regular expressions.

http://www.nakov.com/blog/2009/07/15/jax-rs-path-pathparam-and-optional-parameters/

I would go with having separate endpoint method in Controller where it can pass the call to your services with optional parameter.

What about adding another method annotated with only:

@Path("/expire")

And let this method pass a null value into the original method.
