The object's life cycle is determined by the POA the object is registered in.
However, you can provide objects with a "destroy" operation that automatically
remove themselves from the POA.

So, the answer is yes: it exists. Object life cycle is not determined by the
method/object in which it is created.

No. Method termination has nothing to do with object life cycle.

I think I understand you. I could explain it with somewhat more
detail. However, first of all, you should have clear the difference between
"reference" and "object" in the CORBA world. Without those concepts clear, it
is difficult to explain well what's happening.

No. It indicates that you are not interested any more in the reference on which
you applicate this function. References are remote representatives (or
proxies) of the remote CORBA object.

Object destruction must be carried out in the server and dealing with the POA
in which you registered the object.

    Thanks to you. You should read all above and then ask what exactly you
don't understand right now...

    Best regards.
