A java meta-registry for remote service objects

In this paper we propose a meta-registry system., in what follows referred to as Netlab Java Meta-Registry (N-JMR). that integrates in a single access point tbe content of several RMI registries. N-JMR associates tbe same N-JMR service name to the absolute addresses of different instances or tbe same RMI class. As a consequence N-JMR can select tbe best remote service, among those associated to the- same N-JMR service name, according to some evaluation criterion, selected among those provided by the system. In addition it is pnssible to define and add new evaluation criteria to the system. Furthermore, N-JMR extends the functionality of the RMI naming service by a directory service, thus making it possible to associate many information of interest to N-JMR services names. This information can be accessed both at run-time by client applicatioos and by programmers of distributed systems through web applications.
