Passing Parameters to RestEasy Service

I am trying to figure out how I can pass parameters to the RestEasy setup we have. how we handle parameters is as follows: http://urltojboss7/.../.../resourse/id/val

Where resource is the service we are calling, id is the parameter name, and val is the value of the parameter. When working with SoapUI in eclipse, I didn't see w way to build the call that way.
