Perhaps it is worth opening an enhancement request against JAXWS runtime
?
In meantime, any chnace that you can force Sprion AOP to use CGLIB ? It
might help.

=20
You can probably register a custom input CXF interceptor and configure
it with the names of the methods to be throttled but I'm not right now
how to get the name of the method to be invoked from the Message.
Another option is to register a custom JAXWS invoker (configured with
the names) and check the Method there
=20
cheers, Sergey

	I kind of found the issue. Since, I am doing my own Spring-AOP,
I need to modify the jaxws:endpoint XML config as follows.
	=20
	<jaxws:endpoint  id=3D"XXXService"=20
	   implementorClass=3D"com.xxx.ws.soap.XXXServiceImpl"
	   implementor=3D"#xxxServiceImpl"=20
	  address=3D"/XXXService"/>
	=20
	Because of this, since Spring works on proxies, somehow,
@Resource (WebServiceContext ) is failing. This is because
ResourceInjector (CXF class) works on Fields (using Reflections API)
rather than on methods. If the accessing of WebServiceContext is done
using Methods (Reflections API),  it would not be a problem because
proxies have methods too.
	=20
	So it appears that, we can not have any custom annotations in
CXF implementor classes. I see this is a limitation of CXF (at least for
now). I might need to do some other way of doing Throttling in stead of
using Custom annotations.
	=20
	Has anybody done any custom annotations on CXF implementor class
which have @Resource (WebServiceContext)?

	Hi
	=20
	I have a weird issue. I have a JAX-WS java-first webservice
using CXF and Spring. I have WebServiceContext in my Implementer class.
Here is snippet of my Implementer class
	=20
	@WebService(endpointInterface =3D "com.xxx.ws.soap.XXXService",
serviceName =3D "XXXService")
	@WebFault(targetNamespace =3D "com.xxx.ws.soap", name =3D
"XXXFault", faultBean =3D "XXXFault")
	public class XXXServiceImpl implements XXXService {
	=20
	 @Resource
	 private WebServiceContext webServiceContext;
	=20
	 @Throttle
	 public PatientMatchResp getSomeMethod()
	    throws ApplicationFault {
	 ....
	 ....
	 ....
	 }
=09
	I have a custom annotation @Throttle and would like to do some
work (basically throttling the method such as way that this service is
not abused by users when exposed to public) on that method using Spring
AOP.=20
	=20
	1) My issue is when I started my Tomcat with this
implementation, I am getting this error. Again, this is at the startup
time of Tomcat time. Not at some invocation of webservice time. If I
comment either WebServiceContext OR @Throttle, then, things are OK. Why
is my custom annotation is giving problem for CXF startup?
	=20
	2) Second questions is.. is there a easy way to get hold of
HttpServletRequest into my Aspect (Spring AOP). I don't know whether
this is a right forum or not. Currently, I am trying to get hold of
WebServiceContext using reflections API in my Aspect class and trying to
get HttpServletRequest. Is there an example where I can write a CXF
Handler/Filter and put WebServiceContext  into ThreadLocal so that I can
get it wherever I want down-the-line(here..in this case my Aspect
class)?=20
