I have done a lot of searching and cannot find a concise example of how to map an XML schema to existing domain objects instead of creating brand new ones utilizing xjc. I have created a bindings (xjb) file but still can find no way of accomplishing this.
If I have an existing domain Object that I want JAXB to use such as the following:
package com.blah.domain;
class CustomerOffice{
private int id;
private String name;
private String phone;
}
And I have an XML Schema like the following:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:www="http://www.blah.com"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.blah.com" elementFormDefault="unqualified">
<xs:element name="Customer">
<xs:complexType>
<xs:sequence>
<xs:element name="id" type="xs:int" nillable="false" minOccurs="1" maxOccurs="1"/>
<xs:element name="name" type="xs:string"/>
<xs:element name="city" type="xs:string"/>
<xs:element name="CustomerOffice" type="www:CustomerOffice" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:complexType name="CustomerOffice">
<xs:sequence>
<xs:element name="name" type="xs:string"/>
<xs:element name="length" type="xs:int"/>
</xs:sequence>
</xs:complexType>
</xs:schema>
If I go to generate the JAXB classes with xjc it will create a new class called Customer (which I want). It will also create a new class called CustomerOffice (which I don't want, I want it to use my existing domain object).
So instead of the schema pointing to "type:www:CustomerOffice" I would want it to use the existing com.blah.domain.CustomerOffice.
I tried to make this as simple an example as possible, any help is appreciated.
You can use an external binding file to configure XJC to do what you want.
<jxb:bindings
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
version="2.1">
<jxb:bindings schemaLocation="yourSchema.xsd">
<jxb:bindings node="//xs:complexType[@name='CustomerOffice']">
<jxb:class ref="com.blah.domain.CustomerOffice"/>
</jxb:bindings>
</jxb:bindings>
</jxb:bindings>
XJC Call
xjc -d outputDir -b binding.xml yourSchema.xsd
