JAX-WS - how to create an element of type xs:any from server side code?

I have created an XML schema for my webservice, and the element for ServerResponse contains an unbounded sequence of elements of type xs:any.

I am generating classes (using xjc) from my schema, and so this sequence is converted to List in the generated ServerResponse class.

The ServerResponse class has a method, getAny(), which returns this List and allows me to make changes to it.. but I can't figure out exactly how to do this.

Say I want to add a couple of elements to the sequence of any objects in the response, so that the XML of the response will contain this.

<someelement1>sometext</someelement1>
<someelement2>somemoretext</someelement2>

from the Java server side code, how would I add these two elements to the getAny() object? I thought it could be done something like this:

Object element = new Object();
((Element)element).setNodeValue("someelement1");
((Element)element).setTextContent("sometext");
requestobject.getAny().add(element);

However this doesn't work, as it throws an error stating that "java.开发者_开发技巧lang.object cannot be cast to org.w3.dom.Element".

Can anyone help me do this? I'm sure there's a pretty simple solution!

Thanks for any help :)

Object does not implement Element, so this cast will always fail.

You can create Element instances using a DocumentBuilder which you can get from a DocumentBuilderFactory.

Here is some sample JAXB code:

@XmlRootElement
public class Anything {
  private Object any;

  @XmlAnyElement
  public Object getAny() { return any; }
  public void setAny(Object any) { this.any = any; }

  public static void main(String[] args) throws DOMException,
      ParserConfigurationException {
    Element foo = DocumentBuilderFactory.newInstance()
        .newDocumentBuilder()
        .newDocument()
        .createElement("foo");
    Anything a = new Anything();
    a.setAny(foo);
    JAXB.marshal(a, System.out);
  }
}

I haven't tried this under JAX-WS (JAX-WS uses JAXB bindings) - if it doesn't work, I'd start digging round the javax.xml.soap package.
