A Distributed Object Model for the Java System

Abstract
We show a distributed object model for the Java(tm) System (hereafter
referred to simply as "Java") that retains as much of the semantics of
the Java object model as possible, and only includes differences where
they make sense for distributed objects. The distributed object system
is simple, in that a) distributed objects are easy to use and
to implement, and b) the system itself is easily extensible and
maintainable. We have designed such a model and implemented a system
that supports remote method invocation (RMI) for distributed objects
in Java. This system combines aspects of both the Modula-3 Network
Objects system and Spring's subcontract and includes some novel
features.
To achieve its goal of seamless integration in the language, the
system exploits the use of pickling to transmit arguments and
return values and also exploits unique features of Java in order to
dynamically load stub code to clients (patent pending). The final
system will include distributed reference-counting garbage collection
for distributed objects as well as lazy activation.
