SOAPBody.getElementsByTagName() returns an empty NodeList
---------------------------------------------------------

                 Key: JBWS-2345
                 URL: https://jira.jboss.org/jira/browse/JBWS-2345
             Project: JBoss Web Services
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: jbossws-native
    Affects Versions: jbossws-native-3.0.1
         Environment: JBoss 4.2.3 with jbossws-3.0.1-native-2.0.4.GA (the one that comes with 4.2.3 out of the box)
Windows XP Professional 5.1 Service Pack 2
            Reporter: jrostosk
            Priority: Minor


SOAPHandler uses SOAPMessageContext to get SOAPMessage.
Then get SOAPBody via SOAPMessage.getSOAPBody().
Since SOAPBody extends org.w3c.dom.Element, use the following to get at <arg0>
Element arg0Element = (Element) body.getElementsByTagName("arg0").item(0);
System.out.println("arg0Element is null: " + (arg0Element == null));  // IT'S NULL

Here's the code:
public boolean handleMessage(SOAPMessageContext msgContext)
{
  try
  {
    // see what's coming in
    System.out.println("------INCOMING---------");
    SOAPMessage message = msgContext.getMessage();
    message.writeTo(System.out);
    System.out.println("------------------------");
    
    // get <arg0>
    SOAPBody body = message.getSOAPBody();
    Element arg0Element = (Element) body.getElementsByTagName("arg0").item(0);
    System.out.println("arg0Element is null: " + (arg0Element == null));  // IT'S NULL
    ...
  }
}

Here's the output:
------INCOMING---------
<soapenv:Envelope xmlns:jcat='http://catalog.javatunes.com/' xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/'><soapenv:Body><jcat:findByKeyword xmlns:jcat='http://catalog.javatunes.com/'><arg0>nn
</arg0>
</jcat:findByKeyword>
</soapenv:Body></soapenv:Envelope>
------------------------
arg0Element is null: true

NOTE: the whitespace nodes in the message are added by JBoss somewhere, the source message contained no whitespace. (Shouldn't matter anyway.)
You can see that <soapenv:Body> indeed has an <arg0> element (in no namespace).
I also tried this with <jcat:findByKeyword> using both getElementsByTagName and getElementsByTagNameNS, both yielding same result.
