ABAP Class as web service

Hi All,

Is there any way to expose a ABAP class as a web service. I know we can create a FM or BAPI and expose them as web service.

Ex : If I have a SalesOrder class and this class has methods like getOrder(),getDetails(),getItems() etc etc

Now I would like to create a service where the above methods are methods inside the service.

(We don't have XI in our landscape)

Please correct me if my assumption is wrong.

Thanks ,Anilkumar
