JAXB

Note: You should never directly use the generated implementation classes--that is,

*Impl.java

in the

<packagename>/impl

directory. These classes are not directly

referenceable because the class names in this directory are not standardized by the
JAXB specification. The

ObjectFactory

method is the only portable means to cre-

ate an instance of a schema-derived interface. There is also an

ObjectFac-

tory.newInstance(Class JAXBinterface)

method that enables you to create

instances of interfaces.

These classes and their specific bindings to the source XML schema for the basic
examples are described below.
