Middleware has emerged as an important architectural component in supporting distributed applications. With the expanding role of middleware, however, a number of problems are emerging. Most significantly, it is becoming difficult for a single solution to meet the requirements of a range of application domains. Hence, the paper argues that the next generation of middleware platforms should be both configurable and re-configurable. Furthermore, it is claimed that reflection offers a principled

The main emphasis of the paper is on resource management within this architecture (accessible through one of the meta-models). Through a number of worked examples, we demonstrate that the approach can support introspection, and fine-and coarse-grained adaptation of the resource management framework. We also illustrate how we can achieve multi-faceted adaptation, spanning multiple meta-models. P.
