@XmlAttribute appears as @XmlElement

On my webservice I define a variable as @XmlAttribute:

@XmlAttribute
protected String domain;

But when I make a query via SoapUi, it appears as an XML element:

<ns:domain>domain</ns:domain>

I can't find any mistake in my开发者_高级运维 code..

How do I fix this problem?

You show the annotation on the field, but JAXB uses property (getter/setter method) access by default. Have you changed JAXB's default access? Try putting the annotation on the getter method instead.

Edit: Since you seem to be having trouble, here's an executable example:

import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
import javax.xml.bind.annotation.*;
import java.io.StringWriter;

public static void main(String[] args) throws Exception {
    Foo foo = new Foo("my attribute value", "my element value");
    Marshaller marshaller = JAXBContext.newInstance(Foo.class).createMarshaller();
    StringWriter stringWriter = new StringWriter();
    marshaller.marshal(foo, stringWriter);
    System.out.println(stringWriter);
}

@XmlRootElement
static class Foo {
    private String anAttribute;
    private String anElement;

    Foo() {}

    public Foo(String anAttribute, String anElement) {
        this.anAttribute = anAttribute;
        this.anElement = anElement;
    }

    @XmlAttribute
    public String getAnAttribute() { return anAttribute; }
    @XmlElement
    public String getAnElement() { return anElement; }
}

Output (formatted):

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<foo anAttribute="my attribute value">
    <anElement>my element value</anElement>
</foo>

I've reimplemented the project with the Axis 2 code generator. Now it works.

I don't know what was the mistake..
