session between a ws service and a client in cxf
Hello,
I'm using cxf 2.1.3, and I'd like to know if like in axis
there is the possibility to mantain a conversational state
with a web service, like the setMaintainSession() method of Call in axis do.
(Precisely I publish a cxf service in servicemix, can somebody tell me if I can establish a session with a cxf client or another type of client outside the bus?)
Sorry if I didn't understand or not look at the right documentation,
Please help me.
Thank you in advance,
greetings
silvia

With singleton service beans you will have 50 different Java threads
running in methods of the same service object at the same time. If your
service object is thread safe (which it should be if it is stateless)
this will be fine.

Do you mean a separate instance of the service bean for each request?
You can certainly do that using scope="request" for your service beans
in Spring, or I think there's a way to do it with the
JAXRSServerFactoryBean, but like I say that shouldn't be necessary if
your service object is thread safe.

Yes, that's perfectly normal for server sockets.

What about concurrency?
What happen if i have 50 connections at the same time:
1) Can i create a independent invoke for each process ?
2) All the invoke process are to the same socket number ?

As far as I know, CXF doesn't provide anything for the *client* side of
RESTful services.
For server-side session support you should just be able to make your
service beans session-scoped (with <aop:scoped-proxy/>). See the notes
at the bottom of http://cwiki.apache.org/CXF20DOC/jax-rs-jsr-311.html
about Spring AOP for details of the potential pitfalls. Alternatively
you could use the HttpSession directly by injecting a MessageContext
into a singleton service bean and accessing the HttpServletRequest
through that.

There are some for JAX-RS ?

With JAX-WS, once you have the stub you can do
((BindingProvider)cxfStub).getRequestContext().put(
BindingProvider.SESSION_MAINTAIN_PROPERTY,
Boolean.TRUE);
All JAX-WS client stub objects implement BindingProvider in addition to
the service interface.
