SDO Databinding implementation to CXF

[Luciano Resende <lu...@gmail.com>]

Just FYI, as It seems CXF is working with GSoC students to build a SDO
Databinding [1] possibly based on Tuscany SDO.

One important part of a databinding for CXF is that the "wsdl2java" tooling 
plugin is part of the databinding.  Thus, the proposal can cover a wide 
variety of requirements and use cases.  

Basically, the wsdl2java tool in CXF supports pluggable databindings.  There 
currently exists plugins for XmlBeans and JAXB (JAXB being the default for 
jax-ws compatibility reasons), but is relatively easy to extend to to other 
mappings.   If the databinding has a xsd -> java type tool that can be 
controlled from java and produced a model or similar where we can query qname 
-> classname, producing a databinding plugin for wsdl2java is relatively easy.  
It took me about a week to do the xmlbeans databinding, but some of that was 
just cleaning up some of the stuff that expected jaxbisms.  Subsequent 
databindings should be easier.

Obviously, the GSoC proposal covers more than wsdl2java.   For CXF, we want 
runtime support to then use the SDO  objects.  Basically, mapping all the 
marshalling and unmarshalling stuff into the runtime, configuration, java2ws 
stuff (if applicable), etc....  I mostly just wanted to mention that if the 
project is accepted and is successful, not only would it be a huge new feature 
for CXF, but it could also help out Tuscany.

Anyway, it's definitely an opportunity for the student to engage with both the 
CXF and Tuscany communities which is definitely not a bad thing.
