access common jaxb object from two different parent classes

Question

I have two jaxb-annotated classes generated from jax-ws wsimport. They are "top-level" classes, each referenced from different jax-ws methods.

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Level0MessageType", propOrder = {
    "header",
    "payload"
})
public class Level0MessageType {

    @XmlElement(name = "Header", required = true)
    protected MessageHeaderType header;
    @XmlElement(name = "Payload", required = true)
    protected Level0PayloadType payload;
 ... etc ..
}

and

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Level1MessageType", propOrder = {
    "header",
    "payload"
})
public class Level1MessageType {

    @XmlElement(name = "Header", required = true)
    protected MessageHeaderType header;
    @XmlElement(name = "Payload", required = true)
    protected Level1PayloadType payload;
... etc.
}

They both contain a common "header" element. I need to access that element from the parent object w/o knowing the parent concrete type. I could define an interface and then have both Level0MessageType and Level1MessageType implement a method to return the header, but that means that whenever wsimport re-generates my java classes, I would lose the changed code. Any better solution?

Thanks.

Which exact environment are you using for code generation (maven, ant, IDE only) ? — Hendrik Jander, Feb 13 '16 at 18:09

Netbeand and Maven. I am not using jxc, but wsimport to create the classes. — OldProgrammer, Feb 13 '16 at 18:22
Please add your maven config. XJC is part of your wsimport toolchain, even if not explicitly mentioned. — Hendrik Jander, Feb 13 '16 at 18:28
Yes, I found think link about passing xjc parameter through wsimport. Looking at the duplicate question. — OldProgrammer, Feb 13 '16 at 18:35
