The purchase order code example demonstrates the effects of schema content ordering using the @XmlAccessorOrder annotation at the package and class level, and the @XmlType.propOrder annotation on a class.
Class package-info.java defines @XmlAccessorOrder to be ALPHABETICAL for the package. The public fields shipTo and billTo in class PurchaseOrderType will be affected in the generated schema content order by this rule. Class USAddress defines the @XmlType.propOrder annotation on the class. User of this annotation demonstrates user-defined property order superseding ALPHABETICAL order in the generated schema.
The generated schema file can be found in the tut-install/javaeetutorial5/examples/jaxb/j2s-xmlAccessorOrder/build/schemas/ directory.
