In this paper we introduce the JavaSpaces NetBeans IDE
(JSN) which integrates the JavaSpaces technology, an implementation
of Linda principles in Java, with the NetBeans1
IDE. JSN is a didactic tool for practical assignments during
distributed programming courses. It hides advanced aspects
of JavaSpaces configuration and lets students focus on interprocess
coordination. An important component of JSN is
a distributed debugger which can help to make concurrent
programming classes easier to understand and more compelling.
