Colm O hEigeartaigh commented on CXF-7536:
------------------------------------------
With the fix, you should be able to leave out the SignedSupportingToken policy
element, and the XPath expression will sign the SAML InitiatorToken correctly
using a STR Transform. The next set of releases will be available probably in
3/4 weeks.

> In Apache CXF v3.1.7, I have a JAX-WS web service client calling a service
> that requires a HolderOfKey SAML Assertion. The assertions are from a custom
> service that does not adhere to the WS-Trust SecureTokenService standard, so
> I am adding them manually in a SAMLCallbackHander, using the
> callback.setAssertionElement() method.
> When invoking the client, the WSS4J framework is unable to compute the
> signature for the SecurityTokenReference header block, throwing the below
> error:
> {{
> javax.xml.crypto.dsig.XMLSignatureException:
> javax.xml.crypto.dsig.TransformException:
> org.apache.wss4j.common.ext.WSSecurityException: Referenced token
> "id-of-SAML-assertion" not found
> at
> org.apache.wss4j.dom.str.STRParserUtil.getTokenElement(StrParserUtil.java:314)
> at
> org.apache.wss4j.dom.transform.STRTransformUtil.dereferenceSTR(STRTransformUtil.java:98)
> at
> org.apache.wss4j.dom.transform.STRTransform.transformIt(STRTransform.java:195)}}
> It appears that the SAML assertion DOM Element that is added via the
> callback.setAssertionElement() method is not getting searched by the
> STRParserUtil.getTokenElement() method.
