Hi Mary:
You are Missing the code that sets the namespace feature.
After making a call to the create Parser, you need to set features. I have
included it below.

------------------------------------------------
// set the parser features
try
{
parser.setFeature("http://xml.org/sax/features/namespace-prefixes",true);
}
catch (SAXException e)
{
// note: fix exceptions to print stack trace of original exception
// see ServletUtils.getStackTraceAsString()
//*****
throw new Exception("Error in setting up parser feature " +
"namespace-prefixes.\n You need a parser " +
"which support SAX version 2");
}
