Thanks Ron.
I am specifically interested in CXF framework. Like I understand your
point but the only reason I am going into details is that I can
understand the Web service better as a product or a technology. There
are several concepts like JAXWS, JAXB, WSDL, Schemas....etc and each
plays a significant role in the Web service infrastructure per say.
And there are plenty of Web service based use cases which most of the
people (specially ones like me) don't even know.
I am just going a bit far as I can understand the semantics of this
framework (CXF) better and therefore also understand the Web service
as a technology better.
My apologies if that has confused you. I am just kinda researching and
it can just make me more better equipped to use Web services in projects.
No problem. I was just a bit concerned that you were going to get
frustrated before you had a chance to get something working.
We have been using CXF for over a year now in a production e-Learning
portal that servers over 8000 students.
We added Web Services after we had the portal in production so it had to
go from test to production without a hitch and work well as it had the
day earlier (only faster).
We looked at Axis and CXF and chose CXF because it seemed to be packaged
in a way that kept us from having to invest a lot in learning the
underlying plumbing.
We have been very happy with both performance and ease of development.
There is nothing wrong with the investigation that you are doing and I
am sure that it will give you a higher level of confidence with what you
are about to build.
I am just not sure where the law of diminishing returns sets in with
learning CXF internals since so much seems to work so well right out of
the box if one follows the examples and the documentation.
Ron
Thx

CXF looks after a lot of the plumbing for you and you should be
able to get a simple web service and its clients going without to
much worry about the internal flow.
What are you trying to build?
Is there anything about what you need to do that you expect to be
outside the normal web services pattern?
We were able to build quite a few web services in a simple
Tomcat/Jetspeed portal environment just by following the normal
CXF patterns as described on the site and in the docs.
I did not do the work but my team got things done very quickly
with no big complaints or delays.
It might help if you described your IDE and the frameworks that
you want to use.
For example, we used Eclipse/STS with a Spring, Hibernate, MySQL
and Tomcat.
This probably has an impact on the tools, process and packaging
that people will recommend to you.
Good luck.

Hi Dan,
Thanks for the reply. But still need to understand this. I am
a novice in
Web service and researching on various Web service use cases.
The obvious
and basic ones are consuming the service with the code first
and contract
first approach. Coming to your reply:
1. I can use the generated client and server code (and they do
not use
ObjectFactory or XXResponse classes) and comfortably run my
services. Now as
you said the ObjectFactory is checked by JAXB for xsd:any
type. What
situation makes use of this scenario?
2. XX and XXResponse are used as wrappers @ runtime. It
happens when?
I am sorry for the above questions, it may sound trivial, but
need to
understand the flow. Any pointers will be greatly appreciated.
Thx
Raj

Hi,
When I use wsdl2java with either client or server
option, it generates
ObjectFactory class,
JAXB itself uses that. In cases where there are xsd:any
and similar or
places
where a JAXBElement is needed, it checks the ObjectFactory
for the right
methods for dealing with the actual elements.
XX and XXResponse classes. Why are these classes
generated and where it could be useful?
When available, they are used at runtime. The parameters
(and returns) are
wrappered with these objects and fed into JAXB as one
whole unit instead of
for each param.
