Is it possible to use RMI bidirectional between two classes?

Question

I want to share some information between two classes (A and B), which are running in different java programs. Instead of writing a whole communication protocol I want to use the java build-in rmi classes for that purpose. Currently class B is able to run a method which belongs to class A remotely. Is it somehow possible to use the same "connection" within class A to call a method of class B? Otherwise I probably have to implement a second rmi service ...

BR,

Answer 1

If B implements Remote, it can be export and passed as a parameter in an RMI call to A. In this scenario, there's no need to register B in an RMI registry, since the client is being passed a reference to it explicitly.
