CXF Endpoint is unable to find SAAJ Message Factory

Issue

I am trying to add ws-security information to an outgoing SOAP request within a ServiceMix and a Camel project I have created. I have used what I found regarding this setup from https://github.com/gnodet/camel/tree/trunk/examples/camel-example-reportincident-ws-security-osgi.

This is an exception thrown on bundle deployment:
