Does OO handle importing / interfacing with WADLs?
Working with a product that doesn't have a WSDL - will OO handle WADLs?
I haven't seen anything in the docs yet about it.
Yes. OO supports importing REST API definitions that are stored in WADL files.
To do this you need to use OO 10.x REST wizard and docs.
In addition to WADL, OO supports other popular REST API definition formats such as Swagger and RAML.
Hope it helps,
