JAXB Bindings in embedded XSD

Question

I have a wsdl with an embedded xsd.

<wsdl:definitions name="AcmeService"
    targetNamespace="http://www.acme.com/services/Acme/WcfService"
    xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
    xmlns:tns="http://www.acme.com/services/Acme/WcfService"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <wsdl:types>
        <xsd:schema targetNamespace="http://www.acme.com/services/Acme/WcfService/Imports">
            <xsd:import schemaLocation="http://services01.acme.com/WebServices/AcmeWcfClient/service/AcmeService.svc?xsd=xsd0" namespace="http://www.acme.com/services/Acme/WcfService" />
            <xsd:import schemaLocation="http://services01.acme.com/WebServices/AcmeWcfClient/service/AcmeService.svc?xsd=xsd1" namespace="http://schemas.microsoft.com/2003/10/Serialization/" />
        </xsd:schema>
    </wsdl:types>
    <!-- Some more WSDL Content -->
</wsdl:definitions>

My 'xsd' contains the following definitions:

<xs:schema elementFormDefault="qualified" targetNamespace="http://www.acme.com/services/Acme/WcfService">
    <xs:element name="SetApplication">
        <xs:complexType>
            <xs:sequence>
                <xs:element minOccurs="0" name="application" nillable="true" type="tns:Application"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
    <xs:complexType name="Application">
        <xs:sequence>
            <xs:element minOccurs="0" name="SomeElement" nillable="true" type="xs:string"/>
            <xs:element minOccurs="0" name="AnotherElement" nillable="true" type="xs:string"/>
            <xs:element minOccurs="0" name="AcmeDetails" nillable="true" type="tns:Acme"/>
        </xs:sequence>
    </xs:complexType>
    <xs:element name="Application" nillable="true" type="tns:Application"/>
    <xs:complexType name="Acme">
        <xs:sequence>
            <xs:element minOccurs="0" name="PropertyOne" nillable="true" type="xs:string"/>
            <xs:element minOccurs="0" name="PropertyTwo" nillable="true" type="xs:string"/>
        </xs:sequence>
    </xs:complexType>
    <xs:element name="Acme" nillable="true" type="tns:Acme"/>
    <xs:element name="GetAcmeDetails">
        <xs:complexType>
            <xs:sequence>
                <xs:element minOccurs="0" name="acme" nillable="true" type="tns:Acme"/> <!-- "acme" name is lowercase on purpose -->
            </xs:sequence>
       </xs:complexType>
    </xs:element>
    <xs:element name="GetAcmeDetailsResponse">
        <xs:complexType>
            <xs:sequence>
                <xs:element minOccurs="0" name="GetAcmeDetailsResult" nillable="true" type="tns:Acme"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
</xs:schema>

My problem comes from the fact that, when generating the service stubs using wsimport, I am left with the following definition for Acme:

@XmlType(name = "Acme", namespace = "http://www.acme.com/services/Acme/WcfService", propOrder = {

The issue being that I need both Acme and AcmeDetails to resolve to the same underlying Acme object.

Looking at a couple of other, similar, questions (here, here, and here) I have tried to create a binding using the following XML:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<jaxws:bindings
  xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
  xmlns:jaxws="http://java.sun.com/xml/ns/jaxws"
  xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" jaxb:version="2.1"
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  wsdlLocation="Acme_Service.wsdl">
    <enableWrapperStyle>true</enableWrapperStyle>
    <enableAsyncMapping>false</enableAsyncMapping>
    <jaxws:bindings node="wsdl:definitions/wsdl:types/xs:schema/xs:complexType[@name='Application']/xs:sequence/xs:element[@name='AcmeDetails']">
        <jaxb:class name="AcmeDetails"/>
    </jaxws:bindings>
</jaxws:bindings>

The above binding generates the class 'AcmeDetails' but the XMLType Annotation remains 'Acme'.

Any help in generating bindings to both Acme and AcmeDetails in the above extract greatly appreciated.

External XML schema files imported by the WSDL file can be customized using a JAXB external binding declaration file:

<jxb:bindings xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:jxb="http://java.sun.com/xml/ns/jaxb" version="1.0">
    <jxb:bindings schemaLocation="your-imported-xsd-location" node="/xsd:schema">
        <jxb:schemaBindings>
            <jxb:package name="fromjava.client"/>
        </jxb:schemaBindings>
    </jxb:bindings>
...
</jxb:bindings>

The external JAXB binding declaration file can be passed to wsimport using the -b switch. See the JAX-WS tools documentation for details.
