How to add interface on autogenerated jaxb elements by xsdtojava?

I want to add a super interface for a class autogenerated by jaxb and xsdtojava.
Problem: I can only add the interface on the root element (which I don't want, but just for testing purpose).
The element where I want to apply the inheritance is thelistelement.
The xsd I have not control of.
<xs:schema>
<xs:element name="myRequest">
<xs:complexType>
<xs:sequence>
<xs:element name="thelist">
<xs:complexType>
<xs:sequence>
<xs:element name="thelistelement" maxOccurs="unbounded">
...
binding file:
<jaxb:bindings
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
xmlns:inheritance="http://jaxb2-commons.dev.java.net/basic/inheritance"
jaxb:extensionBindingPrefixes="xjc inheritance"
jaxb:version="2.1">
<!-- this works -->
<jaxb:bindings schemaLocation="xsd/my.xsd">
<jaxb:bindings node="//xs:element[#name='myRequest']">
<inheritance:implements>MyInterface</inheritance:implements>
</jaxb:bindings>
</jaxb:bindings>
<!-- this does NOT work -->
<jaxb:bindings schemaLocation="xsd/my.xsd">
<jaxb:bindings node="//xs:element[#name='thelistelement']">
<inheritance:implements>MyInterface</inheritance:implements>
</jaxb:bindings>
</jaxb:bindings>
</jaxb:bindings>
Running with <extensionArg>-Xinheritance</extensionArg>.
Output should be:
...
List<Thelistelement> thelist;
class Thelistelement implements MyInterface {
}
But the interface is missing on the list element class. Why then does it work on the root element myRequest?

I had to add an /xs:complexType to the node. Don't know why that worked though.
Important to note the single slash before the complexType!
<jaxb:bindings schemaLocation="xsd/my.xsd">
<jaxb:bindings node="//xs:element[#name='thelistelement']/xs:complexType">
<inheritance:implements>MyInterface</inheritance:implements>
</jaxb:bindings>
</jaxb:bindings>

Import JAXB binding snippet into other binding file

For a certain xsd file, I have created a corresponding binding file that does some actions. In my case, annotating ComplexTypes with annotations. Finding the type is done with an XPath expression. The following example demonstrates this:
<jaxb:bindings
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xjc= "http://java.sun.com/xml/ns/jaxb/xjc"
version="2.1"
xmlns:annox="http://annox.dev.java.net" jaxb:extensionBindingPrefixes="annox">
<jaxb:bindings schemaLocation="FirstSchema.xsd" node="/xsd:schema">
<jaxb:bindings node="//xsd:complexType//xsd:element[contains(#type, 'SomeType')]" required="false">
<annox:annotate target="field">#com.example.Type(type = "SomeType")</annox:annotate>
</jaxb:bindings>
//About 100 lines of bindings
</jaxb:bindings>
</jaxb:bindings>
There are more bindings defined than just the single I've shown, but my problem is that the bindings are now executed on the FirstSchema.xsd. I have a lot of other xsd files that require the exact same bindings. If I have over 10 more xsd files, I'd have to copy-paste these bindings every time for every schema.
Is it possible to "extract" the bindings and re-use them for every other xsd file like an import? It's kind of related to this comment/question. The advised solution there is using jaxb:schemaBindings/jaxb:package, but if I understand correctly the following snippet just generates the classes into another package and doesn't really solve the problem?
<jaxb:schemaBindings>
<jaxb:package name="com.example.package"/>
</jaxb:schemaBindings>

You'll be surprized, but old-school XML inclusion works with XJB files.
binding.xjb:
<!DOCTYPE jaxb:bindings [
<!ENTITY gh24type SYSTEM "gh24type.xml">
]>
<jaxb:bindings
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:annox="http://annox.dev.java.net"
jaxb:extensionBindingPrefixes="annox"
jaxb:version="2.1">
<jaxb:bindings schemaLocation="schema.xsd" node="/xsd:schema">
<!-- ... -->
&gh24type;
</jaxb:bindings>
</jaxb:bindings>
gh24type.xml:
<jaxb:bindings node="xsd:complexType[#name='gh24Type']">
<annox:annotate>#javax.annotation.Generated({"jaxb2-annotate-plugin"})</annox:annotate>
</jaxb:bindings>
So basically nothing spectacular, just entity-based XML inclusion. If you have exactly the same fragments, just include your entity several times for each of the schemas in question.
Alternatives would be writing a special plugin to simplify customization. Which might be a good idea anyway.

How to rename a xsd element during xjc java class generation?

I'm generating java classes from xsd with cxf-xjc-plugin.
<?xml version="1.0" encoding="utf-16"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="result">
...
</xsd>
I'm trying to rename the root element using a jaxb-binding.xml file:
<jaxb:bindings
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
jaxb:extensionBindingPrefixes="xjc"
jaxb:version="2.1">
<jaxb:bindings schemaLocation="xsd/myxsd.xsd" node="//xsd:element[#name='result']">
<jaxb:class name="MyNewName" />
</jaxb:bindings>
</jaxb:bindings>
But it does not work. The generated java class is named Result. What might be wrong here?

JAXB: Can't work around collision in ObjectFactory class error

I have a couple of SOAP services (implemented in .Net) that I want to generate a Java stub for. The first service was no problem but the second service threw up the error
WSDLToJava Error:
http://localhost/AMS52/ServiceManagement.svc?xsd=xsd8 [0,0]: Two declarations cause a collision in the ObjectFactory class.
http://localhost/AMS52/ServiceManagement.svc?xsd=xsd11 [0,0]: (Related to above error) This is the other declaration.
Not being too familiar with this stuff I eventually figured out that two imports in the wsdl are stepping on each other toes
<wsdl:types>
<xsd:schema targetNamespace="http://tempuri.org/Imports">
...
<xsd:import schemaLocation="http://localhost/AMS52/ServiceManagement.svc?xsd=xsd8" namespace="http://schemas.datacontract.org/2004/07/Company.Platform.Datatypes.Enums"/>
...
<xsd:import schemaLocation="http://localhost/AMS52/ServiceManagement.svc?xsd=xsd11" namespace="http://schemas.datacontract.org/2004/07/Company.Platform.Datatypes.ServiceManagement"/>
...
The xsd for the first import is of the form
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:tns="http://schemas.datacontract.org/2004/07/Company.Platform.Datatypes.Enums"
elementFormDefault="qualified"
targetNamespace="http://schemas.datacontract.org/2004/07/Company.Platform.Datatypes.Enums">
<xs:simpleType name="DeviceIdiom">
<xs:restriction base="xs:string">
<xs:enumeration value="Auto"/>
<xs:enumeration value="Phone"/>
<xs:enumeration value="Tablet"/>
</xs:restriction>
</xs:simpleType>
<xs:element name="DeviceIdiom" nillable="true" type="tns:DeviceIdiom"/>
<xs:simpleType name="ServiceManagementSORType">
...
More reading and I figured out I had to do something like this
How to resolve collision in the ObjectFactory on wsdl2java?
So my approach has been to try and put a suffix on the end of every simple type (they are all simple types).
So my current command line is
./wsdl2java.bat -impl -server -verbose -autoNameResolution -b bindings.xml ServiceManagement.wsdl
And my binding file is
<jaxb:bindings
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
jaxb:version="2.1">
<jaxb:bindings schemalocation="http://localhost/AMS52/ServiceManagement.svc?xsd=xsd8" node="/xs:schema">
<jaxb:bindings node="//xs:simpleType">
<jaxb:nameXmlTransform>
<jaxb:typeName suffix="Enums" />
</jaxb:nameXmlTransform>
</jaxb:bindings>
</jaxb:bindings>
</jaxb:bindings>
But now I am stuck on this error
XPath evaluation of "//xs:schema" results in empty target node
I can not figure out how to get past this error. I am starting to think it has something to do with the fact it's a .Net service and I have to reference the xsd like so
http://localhost/AMS52/ServiceManagement.svc?xsd=xsd8
Any help greatly appreciated.

Finally figured it out, I replaced
<jaxb:bindings schemalocation="http://localhost/AMS52/ServiceManagement.svc?xsd=xsd8" node="/xs:schema">
with
<jaxb:bindings schemaLocation="http://localhost/AMS52/ServiceManagement.svc?xsd=xsd8" node="/xs:schema">
Not easy to see is it, but note the capital L in schemaLocation - ouch!
Entire problem eventually fixed by mapping the schema for 'Company.Platform.Datatypes.Enums' to a different package with the binding file
<jaxb:bindings
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
jaxb:version="2.1">
<jaxb:bindings schemaLocation="http://localhost/AMS52/ServiceManagement.svc?xsd=xsd8">
<jaxb:schemaBindings>
<jaxb:package name="org.tempuri.enums"/>
</jaxb:schemaBindings>
</jaxb:bindings>

JAXB Root Class Rename using binding.xml

I use the Dali plugin in Eclipse to generate Java classes using an xsd file, which essentially just invokes xjc on the schema file. I used the advice here to resolve naming conflicts by applying an XML binding file to the class generation. This worked well, but I tried to take it a step further by renaming the root element, and the result was that I lost the XmlRootElement annotation. I tried using annox to add the root element annotation back in, but I get this error: Unsupported binding namespace "http://annox.dev.java.net". Perhaps you meant "http://java.sun.com/xml/ns/jaxb/xjc"?
Here is my initial binding.xml file (without annox):
<jaxb:bindings xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/jaxb http://java.sun.com/xml/ns/jaxb/bindingschema_2_0.xsd"
version="2.1">
<!-- Force all classes to be generated at the top level, this will potentially cause name conflicts -->
<jaxb:globalBindings localScoping="toplevel"/>
<jaxb:bindings schemaLocation="mySchema-1.0.0.xsd">
<!-- Rename the root element -->
<jaxb:bindings node="//xs:element[#name='MyRootClassNameIsReallyLong']/xs:complexType">
<jaxb:class name="ShorterName"/>
</jaxb:bindings>
<!-- Rename the Bar class to resolve a naming conflict -->
<jaxb:bindings node="//xs:element[#name='Foo']/xs:complexType/xs:sequence/xs:element[#name='Bar']/xs:complexType">
<jaxb:class name="FooBar"/>
</jaxb:bindings>
</jaxb:bindings>
</jaxb:bindings>
By the way, it's worth noting that the schema file came from a third party, so I have no interest in modifying it. Likewise, I'd rather not tamper with the generated Java files, so that's why I am interested in the binding xml approach.
Edit (9/11/2013) - Here is the binding XML with annox:
<jaxb:bindings xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/jaxb http://java.sun.com/xml/ns/jaxb/bindingschema_2_0.xsd"
xmlns:annox="http://annox.dev.java.net"
version="2.1">
<!-- Force all classes to be generated at the top level, this will potentially cause name conflicts -->
<jaxb:globalBindings localScoping="toplevel"/>
<jaxb:bindings schemaLocation="mySchema-1.0.0.xsd">
<!-- Rename the root element -->
<jaxb:bindings node="//xs:element[#name='MyRootClassNameIsReallyLong']/xs:complexType">
<jaxb:class name="ShorterName"/>
<annox:annotate>
<annox:annotate annox:class="javax.xml.bind.annotation.XmlRootElement" name="MyRootClassNameIsReallyLong" />
</annox:annotate>
</jaxb:bindings>
<!-- Rename the Bar class to resolve a naming conflict -->
<jaxb:bindings node="//xs:element[#name='Foo']/xs:complexType/xs:sequence/xs:element[#name='Bar']/xs:complexType">
<jaxb:class name="FooBar"/>
</jaxb:bindings>
</jaxb:bindings>
</jaxb:bindings>

Annox is an XJC add on, so you in addition to declaring the namespace prefx (xmlns:annox="http://annox.dev.java.net), you also need to declare it as an extensionBindingPrefix.
Your openning tag should then look like this:
<jaxb:bindings xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/jaxb
http://java.sun.com/xml/ns/jaxb/bindingschema_2_0.xsd"
jaxb:extensionBindingPrefix="annox"
version="2.1">
