Im looking desperately for a solution to my problem:
I tried to lookup an session bean - named ServiceEjb - from which i only have one @Remote
interface in my class loader (ie. in the ear or in the unit test runner) from within
another session bean, say the SessionBeanFactory.
That session bean - named ServiceEjb - implements other @Remote interfaces. But i dont
care for them. My code is like the user of the factory pattern: InitialContext().lookup()
ist the factory, i get an session bean, i communicate with it across the one @Remote
interface known to me.
Reason why the other @Remote interface needs to be loaded is that the deserialized
statelessproxystub references it in its internals.
When I activate remote class loading ... i can see that the referenced session bean
interfaces get remotely downloaded... but they are not available for the container that
hosts the referencing session bean.
I have a complete example project I can offer to anyone interested (unfortunately one
cannot attach files here). So please ask.
