XJC External binding file always fails

Question

(see update below on origin of this issue)

Have any issue while trying to run xjc with any type of external binding file. Here's a copy of the binding file I'm try to use:

<jxb:bindings 
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
    xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:pd="http://chubb.com/cpi/polsvc/xmlobj"
    jxb:extensionBindingPrefixes="xjc"
    version="2.1">

    <jxb:bindings schemaLocation="your-schema.xsd">
        <jxb:bindings node="//xs:complexType[@name='AddBankVaultRplyType']">
    </jxb:bindings>
</jxb:bindings>

I know it doesn't do anything, but just trying to get a simple example to run. I'm running the following command:

xjc -extension -b src/main/resources/bindings/cXML.xjb -dtd -d tmp src/main/resources/dtds/cXML.dtd -verbose

And am getting the following errors:

parsing a schema...
[ERROR] Unsupported binding namespace "http://java.sun.com/xml/ns/jaxb". Perhaps you meant "http://java.sun.com/xml/ns/jaxb/xjc"?
  line 7 of file:/Users/nick/Development/wuxi/services/punchout/src/main/resources/bindings/cXML.xjb

Failed to parse a schema.

No matter what I put in the binding file for jaxb items it always files with the Perhaps you meant "http://java.sun.com/xml/ns/jaxb/xjc" type error message.

Am I missing something here? Theses seems like it should be pretty straight forward and I do not know why it's giving me issues.

XJC Version:

xjc -version
xjc 2.2.8-b130911.1802

Thanks!

UPDATE

The original purpose of the xjb file is to fix some issues with a DTD. Specifically naming conflicts such as:

[ERROR] Property "Name" is already defined. Use <jaxb:property> to resolve this conflict.

It's because you're compiling DTDs. That is a very different type of animal, normal bindings don't work with DTDs.

Here's a sample project which compiles DTD. The binding looks as follows:

<?xml version="1.0"?>
<xml-java-binding-schema>
    <options package="org.jvnet.hyperjaxb3.hibernate.mapping"/>
    <element name="hibernate-mapping" type="class"/>
    <element name="class" type="class" class="Clazz">
        <attribute name="subselect" property="SubselectAttribute"/>
    </element>
    <element name="typedef" type="class">
        <attribute name="class" property="Clazz"/>
    </element>
    <element name="import" type="class">
        <attribute name="class" property="Clazz"/>
    </element>
    <element name="composite-id" type="class">
        <attribute name="class" property="Clazz"/>
    </element>
    ...
</xml-java-binding-schema>
