A Java Package for Transparent Code Mobility

We describe the architecture and the implementation of a Java package for code mobility. The framework aims at providing the programmer with primitives to design and implement run-time systems for mobile code systems and languages. The package is intended to be straightforward to use and to make the code migration issue automatic and transparent so that mobile agent systems can be easily prototyped. With this respect the package is general and does not depend on any linguistic mobile code abstraction.
