The net worth of an object-oriented pattern: practical implications of Java RMI

Debugging distributed applications in their run-time environment is notoriously hard and development and testing of application logic must be completed ahead of this step. Using Java RMI allows a developer to separate the two stages (development of the application logic from the deployment of the application in its distributed run-time environment) but the developer must acknowledge a specific pattern from the outset. We present this pattern below: it allows for a stage of fully carried out development of the application in an isolated run-time environment (no network) and makes the switch to a true networked run-time environment completely transparent.
