How can I create a DOM Element without a document?

Question

Working with JAXP, the "Hello world" to create an element is:

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.newDocument();

Element e = doc.createElement("helloElement");
// attributes, append, etc...

this makes the creation of an Element dependent of a document object. Is there any way to create an element without a particular document ? something like:

Element e = DomDocument.createElement("helloElement"); //static method or so ...
return e;

Implementing the Element interface is way too much than necessary!

the purpose is to get a DOM Element from a POJO without the need to pass a document any suggestions ?

No. The way the DOM is designed the Document is a factory for all the other objects, and those objects can only exist within the context of a particular Document. So you're already using the correct approach by creating an empty document from the DocumentBuilder.

You can create your own Document within the POJO and use that to create elements, but then if a caller of your method wants to add the returned Element to their own Document they will first have to "adopt" it by calling adoptNode, as a Document is only allowed to contain nodes that it "owns".
