Java & XML Data Binding

Unmarshalling and Marshalling

At this point, marshalling and unmarshalling should be pretty routine. As in the last chapter, I’ll skip over application-specific business logic and move right to dealing with the actual marshal() and unmarshal() methods. You’ll see that the same principles, and sometimes even commands, used in JAXB and Zeus apply to Castor as well.

You’ll also need an XML document that corresponds to the HR XML Schema detailed earlier. Example 8-2 is such a document and is used throughout the rest of this chapter.
