XJC binding file: override package based on namespace instead of schemaLocation

I'd like to override package for my schema via binding .xjb file.

It is done with:

<schemaBindings>
    <package name="com.schema.common" />
</schemaBindings>

JXC compiler expects context for above code, defined via schemaLocation.

I store .xsd and .xjb files in separate directories and this looks ugly (like all Java EE):

<bindings schemaLocation="../../../../wsdl/common_v47_0/CommonReqRsp.xsd">
    <schemaBindings>
        <package name="com.schema.common" />
    </schemaBindings>
</bindings>

Is it possible to define bindings context without relative path in schemaLocation?

I've seen SCD ("schema component designator"). It looks promising but I can't find reference for this syntax...

Solution

  • Here is the magic of SCD:

    <?xml version="1.0" encoding="UTF-8"?>
<bindings xmlns="http://java.sun.com/xml/ns/jaxb" version='2.1'
          xmlns:xsd="http://www.w3.org/2001/XMLSchema"
          xmlns:tns="http://example/schema/common_v47_0">
    <bindings scd="x-schema::tns">
        <schemaBindings>
            <package name="com.schema.common" />
        </schemaBindings>
    </bindings>
</bindings>

    All parts are important. SCD was introduced in version='2.1'.

    I found reference at https://github.com/highsource/maven-jaxb2-plugin/wiki/Configure-Target-Packages-in-Binding-Files

    SCD is extension of JAXB standard and implementation can be investigated in JAXB RI source tree:
