Multi-Level Mediator-Based Technique for Classes Hot Swapping in Java Applications

It is software system nature to be updated over time; the usual way of updating software is to shut down the system and install the new version, then restart it. This poses problems for applications that have limited down-time. In this paper, we present an approach for building dynamic Java application where its classes can be updated while the program is running. Our approach is based on the features supported by Java language such as dynamic linking, class loader, and Java reflection
