Hi,
to finish this one up, here is a code snipped that does not really resolve the
"real bean", but delivers the expected behaviour:
---
// 0: get the bean (proxy)
Object proxy = FrameworkAdapter.getCurrentInstance().getBean(
beanName);
// 1: un-proxy the Spring Scoped Object
while (proxy instanceof ScopedObject) {
proxy = ((ScopedObject) proxy).getTargetObject();
}
// 2: populate a bean instance of the superclass which the CGLIB proxy
inherits from
Class requiredClass = proxy.getClass().getSuperclass();
Object bean = BeanUtils.instantiateClass(requiredClass);
BeanUtils.copyProperties(proxy, bean);
---
The Variable "bean" now holds an instance of the original class which can then
be marshalled for RMI calls.
My misconception was that I thought, I could get hold of a reference to an
instance of my original bean class when obtaining the Spring ScopedObject's
target. Instead, what you really get is another CGLIB proxy. I assume that
Spring is not aware of this _second_ proxy as this one is crafted by Orchestra.
Hence the condition (proxy instanceof ScopedObject) is false.
Kind regards
malte.
