REST Adapter : Get URL Dynamic Variables for Mapping

Hi Experts,

I need to use SAP REST Adapter in my interface with GET Operation, i have gone through number of blogs, but all are based on NWDS.  But here in my scenario i'm not using NWDS, and i want to GET dynamic Variables from URL and map them with my RFC inputs..

Example : http://<host>:<port>/RESTAdapter/demo/query/customer/26 --- Here 26 is my input parameter in URL, i need to use this in mapping.

Thanks in advance.

Regards,

Venu
