Spring remoting; JdkDynamicAopProxy with no methods

问题

Some back story: I'm in the process of setting up a test environment of an old(er) system (2008). The system is currently in working condition, but we need to start testing it before upgrading. There is a front-end proxy application interacting through Spring (2.5.4) HTTP invoking with a back-end application.

I have the source code and spring related dependencies in place, and I'm able to compile the system through build scripts shipped with the source code. I have set up a local VM acting as my back-end, and the applications are deployed and running on JBoss (4.2.2) on both sides.

I am able to run Soap requests to the proxy, authentication is working, so everything seems to be correct.

Now, the communication between applications through HTTP invoking does not work when I try to reach my servers services.

Here is my setup on the server side:

This creates a bean that holds all of my related services

<bean id="onlineService" class="my.own.class.OnlineService">
    <property name="orderService" ref="orderService" />
    <property name="invalidateService" ref="invalidateService" />
    <property name="checkStatusService" ref="checkStatusService" />
</bean>

Exposing service using http invoker

<bean name="onlineServiceHttp"
    class="org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter">
    <property name="service" ref="onlineService" />
    <property name="serviceInterface" value="my.own.interface.OnlineServiceI" />
</bean>
<bean id="simpleUrlMapping"
    class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="mappings">
        <props>
            <prop key="/onlineServiceHttp">onlineServiceHttp</prop>
        </props>
    </property>
</bean>

This is my client setup:

<!--  Online Service using HTTP Invoker -->
<bean id="onlineservice"
    class="org.springframework.remoting.httpinvoker.HttpInvokerProxyFactoryBean">
    <property name="serviceUrl"
        value="http://${ONLINE_SERVICES_HOST}:8080/vmosvcs/vmoservice/onlineServiceHttp" />
    <property name="serviceInterface" value="my.own.interface.OnlineServiceI" />
</bean>

Finally, create my beans targeted through Soap on my client (the proxy application)

<bean id="orderMarshallEndpoint" class="my.proxy.endpoints.OrderMarshallEndpoint">
    <property name="service" ref="onlineservice" />
</bean>
<bean id="invalidateMarshallEndpoint" class="my.proxy.endpoints.InvalidateMarshallEndpoint">
    <property name="service" ref="onlineservice" />
</bean>
<bean id="checkStatusMarshallEndpoint" class="my.proxy.endpoints.CheckStatusMarshallEndpoint">
    <property name="service" ref="onlineservice" />
</bean>

When I send a Soap request towards for example checkStatusMarshallEndpoint, I get the following error on the client:

CustomAuthenticationManager 16 -----New Request in Proxy ----- 
CustomAuthenticationManager 17 Request sent by username :peter: 
CustomAuthenticationManager 19 Authentication Result:true: 
CheckStatusMarshallEndpoint 22 Check Status request received 
OnlineEndpoint 52 The authenticated partnerId is :imran 
CheckStatusMarshallEndpoint 27 The request is :: serial Number :null: activation Code :[PROTECTED]::imran 

CustomSoapFaultMappingExceptionResolver 28 org.springframework.remoting.RemoteInvocationFailureException: 
Invocation of method [public abstract RmiDataTransferObject OnlineServiceI.getServed(...,...)] 
failed in HTTP invoker remote service at [http://{ONLINE_SERVICE_HOST}:8080/vmosvcs/vmoservice/onlineServiceHttp]; 
nested exception is java.lang.NoSuchMethodException: com.sun.proxy.$Proxy76.getServed(..., ...)

at this spot

RmiDataTransferObject resp = service.getServed(getRequest(csr), OnlineServiceI.CHECK_STATUS_SERVICE);

where RmiDataTransferObject getServed(..., ...) is part of my.own.interface.OnlineServiceI. If I debug the execution, there is a JdkDynamicAopProxy declaring the correct HTTP path, but it has no methods registered. Only the intended interface.

What might I be missing? If I try the HTTP url in the browser, I get a 500, which indicate that the path is correct (something is mapped to that address).
