Extending ElementImpl problems?

[Ali Manji <al...@hotmail.com>]

Hi,

I am making use of xerces 1.4.2 and am trying to create a class that extends
org.apache.xerces.dom.ElementImpl which of course implements Element.

However, when I assign it an instance of this class a value of some value of
type Element, it throws a ClassCastException.

For example, consider:

org.w3c.dom.Element root = new MyElement();
root = (MyElement) document.getDocumentElement();

where MyElement extends ElementImpl.

This will throw the following odd exception:

java.lang.ClassCastException: rg.apache.xerces.dom.DeferredElementNSImpl

Any ideas why this doesn't work or any ideas on how to accomplish this task
some other way

Thanks in advance,
Ali
