An integrated development environment for Java Card

This article describes a Java Card programming environment which to a large extent is generated from formal specifications of the syntax and semantics of Java Card, the Java Card Runtime Environment (JCRE), and the Java Card APIs. The resulting environment consists of a set of tightly integrated and somewhat smart tools, such as a Java-specific structure editor and a simulator which allows an application to be tested before being downloaded to a card. Furthermore, the simulator analyses the applet in question in order to find out the structure of the accepted commands. This information is then used to automatically adapt the GUI of the simulator

A Mechanized Model of the Theory of Objects

In this paper we present a formalization of Abadi's and Cardelli's theory of ob jects in the interactive theorem prover Isabelle/HOL. Our motivation is to build a mechanized HOL-framework for the analysis of a functional calculus for distributed ob jects. In particular, we present (a) a formal model of ob jects and its operational semantics based on de Bruijn indices (b) a parallel reduction relation for ob jects (c) the proof of confluence for the theory of ob jects reusing Nipkow's HOL-framework for the lambda calculus. We expect this framework to be highly reusable and allow further development and mechanized proofs of various aspects of ob ject theory, e.g., distribution, aspect orientation, typing

Exceptions for Algorithmic Skeletons

to appearInternational audienceAlgorithmic Skeletons offer high-level abstractions for parallel programming based on recurrent parallelism patterns. Patterns can be combined and nested into more complex parallelism behaviors. Programmers fill the skeleton patterns with the functional (business) code, which transforms the generic skeleton into a specific application. However, when the functional code generate exceptions, this exposes the programmer to details of the skeleton library, breaking the high-level abstraction principle. Furthermore, related parallel activities must be stopped as the exception is raised. This paper describes how to handle exceptions in Algorithmic Skeletons without breaking the high-level abstractions of the programming model. We describe both the behavior of the framework in a formal way, and its implementation in Java: the Skandium Library
