[jdom-interest] Passing Element parameter in Jax-ws web method

Hi Dehaene

Technically, the Element instance does have a no-arg constructor, only 
it is 'protected', not public.

For you to solve your problem in the short term, you may want to do:

class MyElement extends Element {
   public MyElement() {

Then you can make the method:

public void hello(@WebParam(name = "xmlElement") MyElement element){

I am not familiar enough with the  jax-ws to know whether this will help 
enough.... It will make the implementation a little messier, but, by 
default, JDOM doe s not let you create invalid Elements (which an 
Element without a name would be...).

It is not likely possible to make the no-arg constructor public.

Anothe roption is to create a serialized Element? Element serialization 
(at least in JDOM2) is reliable....
