Using DOM4J XPath

Question

IM going nuts trying to use DOM4J to query something so simple. Here is the input XML file and the code to run the XPath. If I loop through the document using the annoying element and node map thing it works fine and I can get all the nodes. But I want to run an XPath query right to the information I want. Firs time I tried without the URI nodes and this time I tried it with it. Still no luck.
XML FILE
<?xml version="1.0"?>
<configs>
     <config SERVICE="Service Name">
          <detail name="key">value</detail>
     </config>
     <config SERVICE="ProcessErrors">
          <detail name="ErrorEmailAddresses">[email protected]</detail>
     </config>
     <config SERVICE="TestSQLErrors">
          <detail name="ErrorEmailAddresses">[email protected]</detail>
     </config>     
</configs>CODE
File fXmlFile = new File("n:\\config.xml");
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(fXmlFile);
doc.getDocumentElement().normalize();
XPath xpathNodes = new DefaultXPath("//configs/config[@SERVICE='ProcessErrors']/detail[@name='ErrorEmailAddresses']");
HashMap<String, String> mapNodes = new HashMap<String,String>();
xpathNodes.setNamespaceURIs(mapNodes);          
Node exceptionNode = (Node)xpathNodes.selectSingleNode(doc);
System.out.println(exceptionNode);exceptionNode is empty. If I run this same query on the same document in XML spy I get the value.???

For obscure products it's generally better to ask on the forum or mailing list associated with that product. You're more likely to encounter people who have heard of the product and actually know something about it.
On the other hand if it doesn't have a forum or mailing list, or there's no activity on that forum or mailing list, that's a hint you should consider using something more commonly used.
