uml class diagram web service

Question

Hi

How do i draw in UML a class that is using a web service?

Thnx :)

Answer 1

Sounds like a sequence diagram, with client and service instances, where the client makes the call to the service. If the request is synchronous, you'll see the return come back to the client; if not, there's no return.

Answer 2

I would have draw the web service as an interface.

I would put a boundary around the web service to indicate it's located outside my system boundary.
