Yes, this should be possible. CXF supports the CORBA IIOP transport.
Unfortunately the JBoss Fuse 6.0 guide "Using the Web Services Bindings and Transport" does not cover the CORBA IIOP transport. So I doubt any JBoss Fuse documentation covers this transport.
However there should be documentation on using the IIOP transport on http://cxf.apache.org.
I also found this page referencing example CXF projects, including CORBA: http://cxf.apache.org/docs/sample-projects.html
The main idea is to configure the CORBA binding in your CXF wsdl contract. There are tools like idl2wsdl that can help.
In my personal toolbox I also have a simple Camel demo that uses CXF to call an external CORBA server. I can send it to you separately via email if you are interested.
Thanks Mielke ! Sample Project has CORBA example ,will try out that.
I would also like a copy if the Sample Project, I have a simular task
