SV: SV: [jdom-interest] How do you do it in JDOM?

[Chris B.]

That doesn't seem to work for me. When I go....

attributes.addAttribute("http://www.w3.org/XML/1998/namespace", "xml", 
"xmlns:xml", null, "http://www.w3.org/XML/1998/namespace");

I get the error...

org.jdom.input.JDOMParseException: Error on line 2 of document: Illegal 
Namespace prefix: "xml".

Caused by: org.jdom.input.JDOMParseException: Error on line 2 of 
document : Illegal Namespace prefix: "xml".
