Abstract
In this paper we introduce the JavaSpaces NetBeans IDE (JSN) which integrates the JavaSpaces technology, an implementation of Linda principles in Java, with the NetBeans 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.
