Somewhat OT: Data binding recommendations

[Brad O'Hearne <br...@neurofire.com>]

I am curious -- setting aside the greater issue of how it fits into  
CXF for the moment, what is everyone's recommendation for XML-to- 
JavaBean data binding frameworks? What frameworks do you prefer over  
others and why? I have a particular need to assess data binding  
frameworks, and since that's a core part of what CXF does, I thought  
the list users would be a resource to ask.

Oh right. Well there you go, I learnt something today!

Thanks for the tip.

JAXB supports the schema-first style as well.  CXF uses this capability 
for some of the Spring configuration classes (e.g. HTTPClientPolicy) 
which are generated from the schemas at build time.

Personally, I like XMLBeans. I prefer the XML first approach which it
seems to serve well. I've never had any problems with it (e.g.
unsupported document elements/structures) and although I'm sure its
not perfect that's a good enough reason for me to keep working with
it. Maybe I've just been lucky though?

I've often thought of switching to a JAXB solution as standards are a
good thing but I'm wary of something that generates XML from java. It
just makes me think XML-RPC for some reason (always prefered
doc/literal). I'd be interested to hear someone jump in to argue the
case for JAXB though.

Well,  JAXB is by far the best supported in CXF considering that's what JAX-WS 
requires.   All the tooling is there, it's well tested, etc...   JAXB also 
is, in general, the fastest if perfomance is a super important metric.  

The main downside of JAXB compared to some other options for general XML use 
is that it IS a bit lossy.   Stuff it doesn't know about when parsing gets 
completely skipped/ignored.   Comments/Whitespace is discarded.  Etc...   
Thus, you cannot "round trip" xml through JAXB.
