Sample Webservice

I am trying to build a Sample Scenario using the Webservice.

If there is any sample webservice that I can use for my TEST Case.

I want to send the Country name from an R/3 System using an RFC to XI and XI needs to send this request to a Webservice where I will get a response of the corresponding currency of that country and send the response back to the R/3. The whole scenario is Synchronous.

I am planning to use Synch Sender RFC adapter and Sync SOAP Receiver Adapter.

But not having a TEST WEBSERVICE where I can test my Scenario.
