Question

I am currently fronting issues mixing a CXF web service with Spring @Configurable annotation.

From one side I have my CXF web service fully working and configured like this :

<import resource="classpath:some-other-context.xml" />

<jaxws:server id="Init"
        serviceClass="package.to.my.ServiceInterface"
        address="/">
        <jaxws:serviceBean>
            <bean class="package.to.my.BADematInitImpl">
            </bean>
        </jaxws:serviceBean>
</jaxws:server>

<context:spring-configured />

And in my some-other-context.xml is my Spring configuration containing the following Bean’s :

@Configurable(autowire = Autowire.BY_TYPE)
public class MyConfigurable {

    @Autowired(required=true)
    private A a;

    @Autowired(required=true)
    private B b;

    @Autowired(required=true)
    private C c;

...

}

But when I try to create a new instance of MyConfigurable bean into my service, I get a NullPointerException due to the null valued supposed-autowired A,B and C objects.

Any idea ?

I finally found out the problem.

I needed to add this configuration into my third-part application XML files :

<context:load-time-weaver/>

… and add this argument to my jvm launch command line :

-javaagent:"path\to\my\spring-agent.jar"

And it just works like a charm.

I understand that this is because Spring needs at some point to have an entity managing its AOP part so that the dependencies are well injected. It would be interesting if someone had further explanations.
