How do I figure out where CXF is being configured?

I'm working on a ear with 3 wars and this dependency:

<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-bundle</artifactId>
<version>2.7.3</version>
</dependency>

I'm trying to configure the client but cxf doesn't seem to be using a
cxf.xml file I've dropped into WEB-INF/classes My evidence is that it's
invalid xml, and no exceptions get thrown when I use the client. So, how
can I debug where it's finding the cxf.xml file it's using? Thanks.

BTW, is the cxf.xml file only used for the client, or is it used for web
service end points too?
