writing XHTML

Hi,

I'm new to the list. I've already used JDOM, but now I have a problem
where I'd like to ask your help.

I want to produce XHTML files, more precisely Xforms. Here is a sample:

<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:xforms="http://www.w3.org/2002/xforms"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
</html>

The problem is how to set the xmlns:xforms namespace. I get the
following exception:

Exception in thread "main" org.jdom.IllegalNameException: The name
"xmlns:xforms" is not legal for JDOM/XML Namespace prefixs: Namespace
prefixes cannot begin with "xml" in any combination of case.

Here is what I tried:

Namespace ns;
this.root = new Element("html");
// this line below works for "xmlns"
ns = Namespace.getNamespace("http://www.w3.org/1999/xhtml");
this.root.setNamespace(ns);
// problems arise here:
ns = Namespace.getNamespace("xmlns:xforms", "http://www.w3.org/2002/xforms");
this.root.setNamespace(ns);

Thanks,

Laszlo

It should be

Namespace.getNamespace("xforms", "http://www.w3.org/2002/xforms");

The "xmlns:" is not part of the namespace prefix.

It's a strange error message though: "Namespace prefixes cannot begin with
"xml" in any combination of case". What the specification actually says is:

<quote>
All other prefixes beginning with the three-letter sequence x, m, l, in any
case combination, are reserved. This means that:

* users SHOULD NOT use them except as defined by later specifications
* processors MUST NOT treat them as fatal errors.
