Namespaces problem in RampartUtil.getPartsAndElements causes XPath problem: No
Such Function
--------------------------------------------------------------------------------------------
Key: RAMPART-356
URL: https://issues.apache.org/jira/browse/RAMPART-356
Project: Rampart
Issue Type: Bug
Components: rampart-core
Affects Versions: 1.5.2
Reporter: HJHorst
I have a policy which contains an XPath expression to find some elements that
need to be signed:
<sp:SignedElements>
<sp:XPath>/*[namespace-uri()='http://schemas.xmlsoap.org/soap/envelope/' and
local-name()='Envelope']/*[namespace-uri()='http://schemas.xmlsoap.org/soap/envelope/'
and
local-name()='Header']/*[namespace-uri()='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd'
and
local-name()='Security']/*[namespace-uri()='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd'
and local-name()='Timestamp']</sp:XPath>
<sp:XPath>/*[namespace-uri()='http://www.w3.org/2003/05/soap-envelope' and
local-name()='Envelope']/*[namespace-uri()='http://www.w3.org/2003/05/soap-envelope'
and
local-name()='Header']/*[namespace-uri()='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd'
and
local-name()='Security']/*[namespace-uri()='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd'
and local-name()='Timestamp']</sp:XPath>
</sp:SignedElements>
I created a client to call the webservice and I get this exception:

I think the problem is caused by line 1190 of RampartUtil.java:
// decide what exactly is going to be used - only the default
namespaces, or the list of all declared namespaces in the message !
Set namespaces = findAllPrefixNamespaces(envelope, decNamespaces);
Rampart tries to find all namespace declarations from my request envelope, and
with these declarations execute the XPath expression.
My envelope has a default namespace declared somewhere, so there is no prefix.
This causes the exception on line 1211:
List selectedNodes = xp.selectNodes(envelope);
Jaxen assigns my default namespace to the XPath functions and can't find them
anymore.
I think findAllPrefixNamespaces should not be called on the envelope at all,
perhaps on the WSDL, (perhaps not at all see comments on RAMPART-67)
