Newbie still needs help...

[Ralph Largo <ra...@ralphontheweb.com>]

I'm re-posting this as I have not had any responses that solved this. My project is stalled until I find out what the problem is, so please help a poor old toothless programmer suffering from caffein withdrawal. Here is the orig. msg:

(JDK v1.3, NT 4.0 w/SP6, latest Xerces download)

I have the DOMWriter from the Xerces examples. I can run it against the personal-schema.xml file just fine, and the parser works as advertised. However, when I try to use the examples out of the Primer, I get this error. Can anyone help me? I am scratching my head wondering why this error is happening. I thought that you could declare a namespace without something actually being at the URI? (There is a directory at f:\InetPub\wwwroot\Schema). I also tried   xsi:schemaLocation="http://www.ralphontheweb.com/Schema/IPO  http://www.ralphontheweb.com/Schema/ipo.xsd" and all possible combos:

IPO.XSD FILE:
<schema targetNamespace="http://www.ralphontheweb.com/Schema/IPO"
        xmlns="http://www.w3.org/2000/10/XMLSchema"
        xmlns:ipo="http://www.ralphontheweb.com/Schema/IPO">

 <!-- include address constructs -->
 <include

 <element name="purchaseOrder" type="ipo:PurchaseOrderType"/>

 <element name="comment" type="string"/>

 <complexType name="PurchaseOrderType">
  <sequence>
   <element name="shipTo"     type="ipo:Address"/>
   .
   .
   .
(etc)


XML FILE:
<?xml version="1.0"?>
<ipo:purchaseOrder

    <shipTo exportCode="1" xsi:type="ipo:UKAddress">
        <name>Helen Zoe</name>
   .
   .
   .
(etc)

ERROR OUTPUT:
[Error] ipo.xml:6:26: General Schema Error: Grammar with uri : http://www.ralphontheweb.com/Schema/IPO , can not found.

Thanks in advance for your help.
