Yes, you would have to define your component as AOP of class management. See Ebro's presentation on that class alongside the EJB class of objects. Then we know to augment your object with the management implementation in an aspect's interceptor. Also it is our classloaders take care of that. See the work commited by Bill already.

At least that is the goal.

yes but in that case your base object must have an interface. We support interface and POJO access with metadata.

You could in theory. with jdk1.4 you could replace the references to existing objects as you define them of class management dynamically. I hear (see other thread in this forum) that the state of the implementation varies. Of course the new instances would be classes of instance (AOPManagement) and would support the signature. It also means that the clients are calling using reflection.
