Shared class for child element in JAXB in different xmls/roots

Question

In JAXB when using automatic class generation via xjc from xsd scheme.

alpha.xsd

Answer 1

You can use an external binding file to indicate that during class generation we wish to use our existing class for the complex type called Document.

binding.xml

<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="beta.xsd">
        <jxb:bindings node="//xs:element[@name='person']/complexType">
            <jxb:class ref="alpha.Person"/>
        </jxb:bindings>
    </jxb:bindings>
</jxb:bindings>

XJC Call

xjc -b binding.xml beta.xsd

Answer 2

If namespace of person from A will be equals namespace person from B, that xjc has to generate the correct classes.
