I am trying to export a spring bean as service using Spring's application context, I need to have them exported as "prototype" scope, but this is not possible due to OSGi Service registry caching the service as singleton.

Doing some research I came upon a post suggesting to use "session" scope to get around this issue. I am following this tutorial to get this working, but I am stuck with an issue that has to do with class loader not finding an interface.

Here's how I am declaring the bean

<osgi:service id="SimulationExporter" ref="simulationService" interface="org.geppetto.core.simulation.ISimulation"/>
<bean id="simulationService" scope="session" class="org.geppetto.simulation.SimulationService">
<aop:scoped-proxy proxy-target-class="false"/>
</bean>

When exporting the bean to another bundle, I get the following error 

Caused by: java.lang.IllegalArgumentException: interface org.springframework.aop.scope.ScopedObject is not visible from class loader
at java.lang.reflect.Proxy.getProxyClass0(Proxy.java:484)
at java.lang.reflect.Proxy.newProxyInstance(Proxy.java:713)
at org.springframework.aop.framework.JdkDynamicAopProxy.getProxy(JdkDynamicAopProxy.java:117)

The bundle importing the service bean has the dependency org.springframework.aop-3.0.0.RELEASE , and this has also being copied to the virgo repository. Any ideas why would the class loader not find that interface that it needs for scope "session"?

Does your MANIFEST.MF include import packages for aop.scope? If you are using Apache Felix to generate it try adding something like this:

    <Import-Package>org.aopalliance.aop,org.springframework.aop,org.springframework.aop.scope,org.springframework.aop.framework,*</Import-Package>
