Design questions CXF//my need
hi
I'm currently looking at CXF for the needs I have here and I'm having
difficulties to figure out whether it fits. Hopefully some on the ML
could help me (thanks in advance!).
My "ideal" world needs are :
- defining the service in Java through annotations
- publishing it both through some Web Service and REST
- feeding the service with my own Guice managed objects
- making it available through my own web application (namely a wicket one)
- having some documentation (not only the WSDL but as well some docs
based on the written Javadoc) automatically generated in a way that
makes it easy to provide to my service's users
- integration with maven and m2eclipse (ability to launch my web
service as a Java embedded app from eclipse would be a bonus)
Is it possible ? Could you give links/helps/tips ?
Up to now, I found that it was possible to create a web application
delivering Web Service or REST (but both I've no clue) and the others
questions remain unresolved.
Thanks in advance

I'm not sure about some of your questions as I've only worked in
WSDL-first SOAP services. I'm sure others can help with these though.

Yes. There's no direct integration (CXF uses Spring for DI, not
Guice), but you can create an Injector in your service implementation
object's constructor and then do an injectMembers( this ) or whatever
to bring up the rest of your object graph.
Or you could try it via the Spring/Guice integration approach:

Not sure what you mean here -- do you want a single web app to contain
wicket stuff and CXF stuff? It's probably more flexible to build them
into separate WARs that you can deploy alongside each other. But it
may be possible to do this (anyone?).

Yes, this works very well.

Umm, not sure...

Hi Nono,
Filters, providers, dispatch... that could get pretty advanced. I am
currently sticking to just the basic annotations until I could
thoroughly get the experience I need. The following should enable you to
create the basics that you need:
For the ReST part:
http://cwiki.apache.org/CXF20DOC/jax-rs.html#JAX-RS-Understandingthebasics
For the SOAP part:
http://cwiki.apache.org/CXF20DOC/developing-a-service.html#DevelopingaService-JavaFirstDevelopment
Note that this is java-first development. I believe this would be the
easier way of having both in just one implementation class. Preferably
though, you would have most of the annotations in your interface.
If you prefer wsdl-first (or wadl-first for rest), I believe there is
also a section on that as well.
Hope this helps.

I am not sure how it is not as straightforward as it could get. But to
get you jump started, basically just combine/overlap the jax-rs and
jax-ws tags in your service interface. If you use annotation, then you
could just do something of the following:
@WebService(name="Service")
@SOAPBinding(use=Use.LITERAL, style=Style.RPC)
@Consumes("*/*")
@Produces("text/xml")
@Path("/ServicePath")
public interface Service
@PUT
@Path("/Some/Additional/Path/")
@WebMethod
@WebResult(name="resultName")
public long method(
@QueryParam("someParam")
@WebParam(name="someParam")
long someParam
)
and in the implementation:
@WebService(endpointInterface="some.domain.Service",
serviceName="Service", portName="ServicePort")
public class ServiceImpl implements Service{
Simply, just combine the annotations of Jax-rs and jax-ws as specified
in the user's guide.
Hth.

is there some documentation around on how to do them both together ?
The only thing close to it I found is this blog entry :
http://sberyozkin.blogspot.com/2008/07/rest-and-soap-united-in-cxf.html
which makes it seems not straightforward.

Great :)
thanks again !

Definitely. JAX-WS definitely defines a lot around how to do this. With
the upcoming CXF 2.3 version, we're going to be taking this even further by
adding custom annotations for a lot of things that are either not possible
with straight JAX-WS/config things (like adding documentation to the generated
wsdl), or require more complex configuration (to turn on things like
fastinfoset support, schema validation, etc...).
> - publishing it both through some Web Service and REST
This is definitely one of the strong points for CXF compared to some of the
others. CXF implements both JAX-WS and JAX-RS and provides good support to
allow implementations to support both SOAP style interactions and REST style.
> - feeding the service with my own Guice managed objects
I honestly don't know enough about Guice to answer this. In general, we use
Spring.
> - making it available through my own web application (namely a wicket one)
The CXF services would just be an additional service in you web.xml, thus,
they should work find together.

As mentioned above, with 2.3, there will be a new set of annotations to expand
the wsdl:documentation tags in the generated WSDL.

Yep. We like maven. :-)
If you use a maven "war" packaging, it should wire into wtp fairly
automatically which would allow it to launch in eclipse. That said, it's
also very easy to create a quick "main" method to start any service (or in
your setUp method for a unit test or similar).
