Java Remote Method Invocation (RMI)
RMI was Java’s first native solution for distributed computing, RMI API performs remote method invocation on objects, in a similar fashion to RPC.
It operates on a Client/Server architecture, where remote objects can be invoked from another JVM, remote objects are referenced in a RMI Registry.
Clients lookup services in the Registry and retrieves a stub that allows it to invoke methods in the remote object.
Java RMI was part of Sund JDK 1.1 and a prior release RMI-IIOP included support for CORBA (Common Object Request Broker Architecture).
Although RMI is still supported it’s a limited solutions, used mostly within Java application, it also doesn’t support authorization off the shelf.
