Java CXF生成的客户端不'；不包括SOAP头

使用Apache CXF发行版中部署的示例wsdl

我在pom.xml中配置了一个小型Maven项目，其中包含以下（cxf codegen插件）代码生成设置：

...

我的实现有什么问题

public class Test3 {
    public static void main(String[] args) throws JAXBException {
        System.setProperty("com.sun.xml.ws.transport.http.client.HttpTransportPipe.dump", "true");
        System.setProperty("com.sun.xml.internal.ws.transport.http.client.HttpTransportPipe.dump", "true");
        System.setProperty("com.sun.xml.ws.transport.http.HttpAdapter.dump", "true");
        System.setProperty("com.sun.xml.internal.ws.transport.http.HttpAdapter.dump", "true");

        String url = "http://www.mmm.xxx/yyy/zzz";
        SOAPService service = new SOAPService();
        Greeter client = service.getSoapPort();
        BindingProvider bp = (BindingProvider) client;

        bp.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, url);

        List<Header> headers = new ArrayList<Header>();
        Header dummyHeader = new Header(new QName("uri:org.apache.cxf", "dummy"), "decapitated", new JAXBDataBinding(String.class));
        headers.add(dummyHeader);

        bp.getRequestContext().put(Header.HEADER_LIST, headers);

        String response = client.greetMe("CIAO!");
    }
}
