Collapse the HelloService project
because you do not need to see it anymore, and expand the HelloWorldLibrary project.
Then expand its Interface and Web
Service Ports categories to see what has been copied in
from that WSDL file, as shown here: Note: When
you have your own existing Web service, you can similarly copy it
to a library or module project by using the clipboard or by dragging
and dropping it from the Windows file system, or by using File
> Import > Business Integration > WSDL/Interface. The
latter option is suggested for more complicated WSDL files that include
references to other files.
Note: You might be wondering what
the annotation is on the upper right of the icons for the interface
and port. This annotation indicates that the interface and port are
part of a WSDL file that contains multiple objects that can be extracted
by right-clicking and selecting Refactor > Extract WSDL
Components. However, you do not need to perform that task
in this sample.
