How to use @Inject or @EJB in a CXF interceptor context?

Question

Is there a way to use @Inject or @EJB in a CXF interceptor? I know I can still do a JNDI lookup but I'd rather avoid it.

I find it weird that JAX-WS handlers are managed but CXF interceptors are not. Is it possible to make them managed? I'm using annotations to add my interceptors to the endpoint (@org.apache.cxf.interceptor.InInterceptors and @org.apache.cxf.interceptor.InInterceptors), could it be handled with a configuration file?

Configuration:

• Java 6
• JBoss EAP 6.1 (AS 7.2)
• CXF 2.6.6

has there been any update in 2 years ? Do I start bounty ? – Truism

@Truism No, no update as far as I know, CXF interceptors are still not managed by the container. But if you use CDI 1.1+, you can use CDI.current(), see #24799029 – Dissimulate

Thank you for the response. I had just figured it and got it working that way. And yes I use Wildfly which supports JEE 7. – Truism

@ulab: I'm quite curious how you got this to work.. If I use the constructor of the interceptor to lookup by means of CDI.current() I get: WFLYWELD0039: Singleton not set for org.jboss.ws.common.utils.DelegateClassLoader – Phrenology

@Phrenology my use case was simple. I tried to get in handleMessge() and not in the constructor. Please see my answer below. – Truism

@ulab. Thanks. That would be very similar to having a request scoped lookup. Since there is a jndi lookup behind the object I factorise I was looking for a lookup with the same scope as the bean, which implements the webservice. But I realize I can possibly work around this with an application scoped bean producing the remote bean I actually need in order to be more efficient (save jndi lookup) – Phrenology

It all feels a bit clunky. Would be so much better if I could directly inject on the constructor of the interceptor – Phrenology

I have injected with the help of CDI 1.1 as below.

CallerInfoInterceptor.java (CXF Interceptor)

public class CallerInfoInterceptor extends AbstractPhaseInterceptor<Message>  {

    @Inject CallerInfoBean callerInfo; // bean

    public CallerInfoInterceptor() {
        super(Phase.RECEIVE);
    }

    @Override

     if (callerInfo == null) {
