Get original exported object back?

Question

It just sunk in that when I pass out my Project as an IProject, its actually going out as a Proxy. So when I get back in another interface IProject I cant then do this;
void remoteCall(IProject project){
    Project proj = (Project) project;
}Is there any utility already in RMI that will get my my original object back? Or should I get it back myself? I thought toStub would do that, but it really did not do anything..
Thanks!

Answer 1

Unfortunately, RMI holds onto
the object returned from the exportObject call (I
think since I implemented unreferenced but its not
been called), and it does not hold onto the object
passed into that call. It has a strong reference to the stub and a weak
reference to the remote object.
Indeed. What I said above is sort of backwards.
My Remote object implements Unreferenced. I holda
weak reference to my remote object. The weak
reference is cleared, but unreference is never
called.This just means that DGC has never found the object
to be releasable. This is completely separate from
local GC.
The local GC can't reclaim an object that the DGC has yet to release.
DGC runs every ten minutes or so but this should
start immediately a client receives a stub, i.e. not
ten minutes later. This acquires a DGC lease, then it
tries to renew the lease in the middle of the
10-minute expiry time.Thats what I was expecting. But its kind of a misnomer. The DGC is always running. Its only checking for expiration every 10 minutes. In the meantime, any objects that the client explicitly says it does not need, the DGC may reclaim at any time.
In the end I am using a WeakHashMap to hold my remote objects. Its my first time finding a use for that weird map...
