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 the content
of several RMI registries. N-JMR associates the same N
JMR service name to the absolute addresses of different
instances of the same RMI class. As a consequence N
JMR can select the 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 possible 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
any information of interest to N-JMR services names.
This information can be accessed both at run-time by
client applications and by programmers of distributed
systems through web applications.
