On first sight I thought it's about my free time project.
Then I noticed the diff ;)

Hi all,
I have been seeing the XFire and CXF projects mature of the last few years
and really like the approach. Great work guys.
J2XB is an open source for Data Binding with some novel ideas.
I have been running for some time trying to prove a point - that you can
define a complete service interface in Java using only Java code and
annotations.
JAXB + JAX-WS already allows this. :-) We've been trying to prove the same
point for quite some time. :-)
A Service interface includes the WSDL generation including XML Schema
generation with full facets supports, inheritance, customized structure
mapping, etc.
Again, JAXB + JAX-WS, although we can also do so with Aegis.
In addition, it has novel support for model classes which do not have
default constructors and require the use of complex constructors or
factories.
Now that starts getting interesting.
The J2XB site is at http://j2xb.sourceforge.net/
I am currently thinking about returning to the J2XB project to add
additional novel ideas for adding comments and documentation to the
generated WSDL and for complete interfaces inheritance support, as well as
thoughts about enabling a second mapping configuration alternative as XML
instead of annotations.
I am basically asking you guys two questions
1. Is there an interest in integrating J2XB 1.1 as it is now with Apache
CFX?
Well, I haven't seen any demand for it from CXF users specifically, but it may
be valuable, possibly for J2XB users. Having never followed J2XB at all, I'm
not sure how valuable it would be to them.
The main issue, looking at the javadoc API's, is that it seems to be fairly
"file based" and not really stream based, and definitely preferrable Stax
based. That definitely will make it MUCH harder to integrate into CXF.
CXF pretty much uses Stax (XMLStreamWriter/XMLStreamReader) things for pretty
much all interaction with the databinding layer. If the databinding supports
that, it's usually not hard to integrate into CXF.
You could look at the XMLBeans databinding as an example:
http://svn.apache.org/repos/asf//cxf/trunk/rt/databinding/xmlbeans/src/main/java/org/apache/cxf/xmlbeans/
or the SDO databinging:
http://svn.apache.org/repos/asf//cxf/trunk/rt/databinding/sdo/src/main/java/org/apache/cxf/sdo
Particularly the DataWriterImpls and DataReaderImpls.
Likewise, for generating the Schemas to stick in the generated wsdl, we would
need to generate into either:
1) DOMs
2) Stax (which we would then go to DOM)
3) org.apache XmlSchema schema objects (eventually, the DOM's from above go
into this)
2. Is there an interest in continuing the work of the J2XB project either
as joining it or as taking the ideas (including the ones I am thinking of
for J2XB 2.0) to existing frameworks in CFX?
Having never heard of J2XB before, I really have no idea. :-)
