+1 and that's why I'm here looking for the correct solution :-)

What I've outlined is what I had to do to get the "native" JBossWS stack (which uses JAXB, right?) to work with a set of Java bindings that are not JAXB annotated.  Kohsuke Kawaguchi has confirmed that this is the correct solution from a JAXB perspective, so I guess what we need to do here is figure out how this all fits into your view of the world ala the JBossWS SPI etc

OK.  It's basically as I outlined in the JAXB forum post...

So JAXB requires the java bindings it's trying to unmarshal the SOAP message into to have JAXB annotations.  In the JBossESB usecase, this is very often going to be impossible because the interface is probably owned by something outside the ESB (i.e. we can't modify them to add the annotations).  

An ESB example of this that we continually use is where the ESB is being used to expose a Webservice interface for a legacy EJB based Service.  The EJB remote interface is already defined and is what we want to base our ESB "hosted" (interpret loosely) JSR181 endpoint - the EJB wrapper Webservice.  

Our current solution to all this from a JBossESB + JBossWS 2.0.x perspective is as outlined in that JAXB forum post.

How the SPI exposes this is up to you for sure.
