A String is an object. Basically, an “Object” in the sense of a what is shown Developer is any Java object that isn’t of an explicitly supported type. As you undoubtedly know, all “things” in Java are objects. Developer/IS has explicite support for String, Long, Double, etc.
When mapping, a String in the pipeline can be mapped to an Object input if that is what is exposed by the service–and the service indicates it supports being passed a String object.
There isn’t any notion of converting a String to an object–it already is an object.
