How can I tell wsimport that separate WSDL files are referring to the same object classes?

Question

I have three different JAX-WS services which use the same classes on the server (e.g. ServiceA, ServiceB, and ServiceC, all of which use MyCommonClass as a parameter). Another module we are developing is using wsimport to create a client for these services, however the problem is that wsimport creates separate instances of MyCommonClass for each service:

• com.company.servicea.endpoint.MyCommonClass
• com.company.serviceb.endpoint.MyCommonClass
• etc.

I know that I could use the wsimport -p option to specify a common package for each endpoint, however I'd like to keep most of the classes in separate packages, but just to share certain common ones. From what I have read it sounds like a JAXB bindings file(s) might be able to help, but I haven't yet figured out the exact syntax to achieve the desired result. I think I'll need a separate bindings file for each service (as I call wsimport once for each one), which looks something like this:

<?xml version="1.0" encoding="UTF-8"?>
<bindings xmlns="http://java.sun.com/xml/ns/jaxb" version="2.1" xmlns:tns="http://endpoint.servicea.company.com/">
  <bindings node="//xsd:complexType[@name='myCommonClass']">
    <class name="com.company.model.MyCommonClass"/>
  </bindings>
</bindings>

Am I on the right track? Or do you have any alternative solutions to the problem?

Define your common classes in an xsd and import it in to the service WSDL's. Then use the schema customization to generate definitions in this schema in to a separate package like "com.company.model"

<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="model.xsd" node="/xsd:schema">
        <jxb:schemaBindings>
        <jxb:package name="com.company.model"/>
        </jxb:schemaBindings>
</jxb:bindings>
