Creating root element w/reference to XSD file

Question

I'm using JDOM and would like to know how to create the root element so it
looks like this:
<Import xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://www.mydomain.com/XSDfilename.xsd">

I am trying to create a xml file with then serves as an input to a vendor tool
I tried creating the root element with default namespace but the second elemnt is also created with the default namespace. I am using Jdom to create this xml file .
My program output:
<?xml version="1.0" encoding="UTF-8"?>
<PacketGroup xmlns="http://www.abc.com/schemas/idwebarchive/data">
<DefaultPacket xmlns="" logonid="scott" password="humptydumpty">
<IndexLevel level="1" containerDesc="" containerName="Recorder Docs" />
<IndexLevel level="2" containerName="Recorded Year" containerDesc="">
<Keyword name="Recorded Year" value="2005" />
</IndexLevel>
<DocumentLevel documentName="Documents" docDesc="" >
<Keyword name="Document Number" value="2005-034378" />
</DocumentLevel>
</DefaultPacket>
</PacketGroup>
Vendor REquirement:
<?xml version="1.0" encoding="UTF-8"?>
<PacketGroup xmlns="http://www.abc.com/schemas/idwebarchive/data">
<DefaultPacket logonid="scott" password="humptydumpty">
<IndexLevel level="1" containerDesc="" containerName="Recorder Docs" />
<IndexLevel level="2" containerName="Recorded Year" containerDesc="">
<Keyword name="Recorded Year" value="2005" />
</IndexLevel>
<DocumentLevel documentName="Documents" docDesc="" >
<Keyword name="Document Number" value="2005-034378" />
</DocumentLevel>
</DefaultPacket>
</PacketGroup>
How do I go about creating this structure without the default namespace in my subsequent elements.
Any help is appreciated , I am new to this aspect of programming
Thanks
