------------------------------------------------------------------
Hi,
Here is the reason as I think for this NPE issue, please help me with this. We
have an element as follows,
<Element xmlns:ns="http://apache/axiom/dom/ns"/>
When the ele.setAttributeNS( ); is called, the xmlns:ns attribute is created
setting the Document object as the Owner, Is it the correct behavior ?
Shouldn't the Element object be the owner ?
Inside the method attr.lookupNamespaceURI( ) , AXIOM returns NULL as the owner
of this attribute.[This is because the Document object has set as the owner,
but not the Element object]. Can a document be the owner of an attribute
instead an Element ?
Thanks,
-Suresh

Inside the method attr.lookupNamespaceURI( ) , AXIOM returns NULL as the parent

> Axiom 1.2.13 implementation's NodeImpl has not implemented methods such as
> lookupPrefix(), isDefaultNamespace(), lookupNamespaceURI() etc and they
> throws UnsupportedOperationException. But these methods are required methods
> for WSS4J libraries such as OpenSAML. Since these methods are not implemented
> WSS4J fails when processing SAML assertions and hence Rampart Trust module
> fails. This is a blocking issue for Apache Rampart.
> Following is the stack trace you get when trying Apache Rampart policy
> sample05. For further info on how to run Rampart samples please refer this
