expose REST service in PI

Hi all,

I kindly ask if it's possible to expose a REST web service with PI to be called from an external application.

I've created many scenarios in wich I created a SOAP service (from service interface) in PI and I was able to call the service from an external application (e.g. SOAPUi).

Is it possible to make the same thing exposing a REST service (the url should contain parameters).

I've seen some discussions and blogs with examples of usage of "SOAP Axis" but it seems it's be possible only to invoke an external service.

Is it possible also to create a REST web-service?

If yes could you please provide examples or step-by-step procedure?

Thanks in advance for any help.

Stefano.
