Abstract
Dynamic loading of code is a crucial and often neglected part of today’s distributed systems that face increasing dynamics, complexity and heterogeneity. Ubiquitous computing and mobile computing even strengthen this trend. As the local availability of suitable code cannot be assumed in such environments, we propose a generic, decentralised code loading infrastructure. The whole process of publication, look-up, implementation selection and the final loading of platform-specific code is decentralised and requires only basic peer-to-peer functionality. In contrast to previous work, our infrastructure allows any peer participating in the network to offer and to obtain platform-specific code in a dynamic and heterogeneous environment. By building on our generic concept, we present a JXTA-based service for dynamic code loading, which is realised by extending and improving JXTA-built-in mechanisms for dynamic service integration. Subsequently, we show the practical application of our infrastructure by an integration into our CORBA middleware and an implementation of mobile objects and mobile web services.
