As we can see, a method called inchesToCentimeters() (the name of the web
service operation we dragged to the source code) is automatically added. This
method in turn invokes a couple of methods in a class called UnitConversion_
Service . This class (and several others) is automatically generated when we drag the
web service operation to our code. We can see the generated classes by expanding
the Generated Sources (jax-ws) node in our project window.
