External Binding Customization Files

<< Inline Customizations | Restrictions for External Binding Customizations >>

SING

Customizations to JAXB bindings made by means of an external file containing
binding declarations take the general form shown below.

<jxb:bindings schemaLocation = "xs:anyURI">
<jxb:bindings node = "xs:string">*
<binding declaration>
<jxb:bindings>
</jxb:bindings>

schemaLocation

is a URI reference to the remote schema

node

is an XPath 1.0 expression that identifies the schema node within

schemaLocation

to which the given binding declaration is associated.

For example, the first

schemaLocation

node

declaration in a JAXB binding dec-

larations file specifies the schema name and the root schema node:

<jxb:bindings schemaLocation="po.xsd" node="/xs:schema">

A subsequent

schemaLocation/node

declaration, say for a

simpleType

element

named

ZipCodeType

in the above schema, would take the form:

<jxb:bindings node="//xs:simpleType[@name='ZipCodeType']">

Binding Customization File Format

Binding customization files should be straight ASCII text. The name or exten-
sion does not matter, although a typical extension, used in this chapter, is

.xjb

Passing Customization Files to the JAXB Binding
Compiler

Customization files containing binding declarations are passed to the JAXB
Binding compiler,

xjc

, using the following syntax:

xjc -b <file> <schema>

where

<file>

is the name of binding customization file, and

<schema>

is the

name of the schema(s) you want to pass to the binding compiler.
