Several namespaces in root element

Question

Hi,
I'm using JDOM and I would like to create an XML document that starts like this:
<Invoice xmlns="urn:oasis:names:specification:ubl:schema:xsd:Invoice-1.0"
xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-1.0"
xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-1.0"
xmlns:ccts="urn:oasis:names:specification:ubl:schema:xsd:CoreComponentParameters-1.0"
xmlns:cur="urn:oasis:names:specification:ubl:schema:xsd:CurrencyCode-1.0"
xmlns:sdt="urn:oasis:names:specification:ubl:schema:xsd:SpecializedDatatypes-1.0"
xmlns:udt="urn:oasis:names:specification:ubl:schema:xsd:UnspecializedDatatypes-1.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="urn:oasis:names:specification:ubl:schema:xsd:Invoice-1.0 UBL-Invoice-1.0.xsd">
</Invoice>
Is there a way to add several namespaces to the root element?? I have tried hard, but nothing works...
Thank you very much for your help,
Susana

OK, it's like dvohra09 said. I had an old copy of jdom.jar and the method addNamespaceDeclaration() didn't exist.
So, here you have the code to generate the beginning of my file, if ever it's useful to someone as I found it a little bit complicated to find out:
For this:
<?xml version="1.0" encoding="UTF-8"?>
<Invoice xmlns="urn:oasis:names:specification:ubl:schema:xsd:Invoice-1.0"
xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-1.0" xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"
xsi:schemaLocation="urn:oasis:names:specification:ubl:schema:xsd:Invoice-1.0 UBL-Invoice-1.0.xsd">
     <ID>serie1_04/00011</ID>
     <cbc:CopyIndicator>false</cbc:CopyIndicator>
</Invoice>
The code is:
Element rootElement = new Element("Invoice", "urn:oasis:names:specification:ubl:schema:xsd:Invoice-1.0");
rootElement.addNamespaceDeclaration(Namespace.getNamespace("cbc", "urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-1.0"));("schemaLocation", "urn:oasis:names:specification:ubl:schema:xsd:Invoice-1.0 UBL-Invoice-1.0.xsd", Namespace.getNamespace("xsi", "http://www.w3.org/2000/10/XMLSchema-instance" ));
rootElement.setAttribute(schemaLoc);
Document invoiceDocument = new Document(rootElement);
// ID          
rootElement.addContent(new Element("ID", "urn:oasis:names:specification:ubl:schema:xsd:Invoice-1.0").setText(invoice.getId_serie_desc() + "_" + invoice.getNum_factura()));
// cbc:CopyIndicator     
rootElement.addContent(new Element("CopyIndicator", "cbc",
"urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-1.0").setText(copyIndicator));
Thank you for your answers.
