It is 'exported' by the RMI Runtime system.

This happens when it is exported by the RMI runtime system.

It becomes ready to receive incoming remote calls via a TCP listening

Wherever the JVM that executes them is running.

1. A remote object is exported.
2. It can be bound in the RMI registry, or returned as the result of
another remote method.
3. The client acquires the stub for the object, from the Registry or via
another remote method on another remote object.
4. The client executes methods on the stub, which are marshalled and
passed over the network to the exporting JVM, where they are executed,
and the return value or exception is returned over the network to the

You should read the the RMI Tutorial.
