Distribution Mechanisms in Java

As a young coding language conceived for use in networked environments from the outset, Java offers more options to realize distributed apps. After all, distribution means that bits and bytes are moved from one process to another over a network. This communication can be implemented in various abstraction layers:

RMI and EJBs are interesting representatives of their kind, thanks to their high abstraction level and their specialization for Java. For this reason, we will discuss below what unit testing can look like in the RMI and EJB environments. To follow the rest of this chapter you should know at least the basics of these technologies. [2] [1]Well, not quite, because an RMI connection for IBM's VisualAge for Smalltalk is available. [2]There is plenty of introductory material on the Web, including online tutorials for both RMI [URL:RMITutorial] and EJB [URL:EJBTutorial].
