Namespace repairing performed by StAXOMBuilder is incomplete with default
namespaces
------------------------------------------------------------------------------------
Key: AXIOM-408
URL: https://issues.apache.org/jira/browse/AXIOM-408
Project: Axiom
Issue Type: Bug
Affects Versions: 1.2.12
Reporter: Andreas Veithen
Assignee: Andreas Veithen
Priority: Minor
Fix For: 1.2.13
The issue can be reproduced with the following code that uses Axis2's BeanUtil
class (which creates an OMElement from a custom XMLStreamReader implementation):
OMElement element = BeanUtil.getOMElement(new QName("urn:test", "test"), new
Object[]{ new DataHandler("test", "text/plain") }, null, false, null);
System.out.println(element);
System.out.println(element.getFirstElement().getAllDeclaredNamespaces().hasNext());
The output is:
<test xmlns="urn:test"><arg0 xmlns="">dGVzdA==</arg0></test>
false
This shows that xmlns="" is added by the serializer, but is not present in the
object model. This is incorrect because the builder is also expected to perform
namespace repairing, i.e. it should have added the corresponding namespace
declaration when the object model was built.
This is likely to cause issues in Rampart, in particular if DOOM is enabled.
The reason is that the object model is passed to WSS4J/Santuario which expects
the namespace information to be complete. Missing namespace declarations are
likely to cause incorrect signature calculations.
