It occurred to me that I might want to clarify what I'm asking, since it's a slightly complicated scenario. As my immediate exception is an aegis.DatabindingException, I was hoping somebody with good experience with CXF & aegis could look at my mapping file setup and / or annotations. Since they don't seem to be having any effect I suspect I'm doing something ignorant, as I am pretty inexperienced with CXF and Aegis.
Also, I'm pretty green to this code, is it foolish to try to expose the same service via mule *and* the web app? They are exposed at different addresses, but it's the same code, the mule service definition refers to the same spring bean successfully exposed by CXF and the web app. Do implementation details preclude exposing this same service via mule at a different address? The web app is successfully publishing the service at /services/FooService, but the mule configuration at /mule/FooService is hitting the binding exception. If I make a request of a /mule/* URL the mule servlet gets invoked but can't find the endpoint, I think because it failed o get properly created due to the binding exception. My goal is to integrate mule into appfuse (and mule embeds cxf), but perhaps I'm taking a misstep in my pursuit of this. Should I perhaps suppress the web app's publication of services? I'm not seeing any conflict with ports or anything unless that's somehow involved with this binding exception but I'm new to both mule and CXF (I have more experience with appfuse and want to exploit it's web app capabilities and add mule in). It's a common scenario to load mule in web apps but most of the code on the mule site has very rudimentary web apps while appfuse has fairly high production values by comparison, I want to add mule to that rich environment. I am at liberty to share the code, there's not any "client" IP involved (hence the FooService), if anybody's interested, I can post it or send it to you.
