Reflection for Adaptable Mobility - Experiences from a project on a reflective system for strong mobile systems
Mario Sudhölt, École des Mines de Nantes.

We present our experiences gained from a project supported by France Telecom R&D on a reflective system for strong mobile systems. We argue that separation of concerns can be advantageously applied to the development of applications relying on weak mobility (i.e. moving and executing code) and coarse-grained strong mobility (i.e. moving distributed entities while these entities are executing). We present the design of an infrastructure for such mobile applications where the mobility concern is cleanly separated from other concerns. We present an overview of a prototype implementation --- called RAM (Reflection for Adaptable Mobility) --- of such an infrastructure for strong mobility in Java by means of computational reflection. This infrastructure permits the development of mobile applications by plugging a mobility concern implemented at the meta-level into a sequential base program, and enables the dynamic introduction of different migration policies. We discuss an implementation of such an infrastructure based on program transformation techniques using appropriate existing tools (Javassist,, and JavaGo, Based on the results of this project, we discuss how the relationships of reflective systems for mobile systems with two larger but closely related contexts:

Reflective Security
Ian Welch, Department of Computing, University of Newcastle upon Tyne.

This talk will discuss the use of reflection to enable a separation between security and application level concerns. The talk will cover:

The Development of OpenORB
Geoff Coulson, Distributed Multimedia Research Group, Department of Computing, Lancaster University.

This talk will discuss experiences with the design of a reflective middleware platform called OpenORB v2 that addresses the following requirements: The platform is built using a well-founded lightweight component model built on the heart of Microsoft's COM (but without COM's higher levels), uses reflective techniques to facilitate (re)configuration, and employs the notion of component frameworks to manage and constrain the scope of reconfiguration operations.
