The paper describes a framework used to develop mobile collaborative applications in Java 2 Micro Edition (J2ME). The framework focuses on the support for same-placesame-time collaboration on mobile phones utilising personal area networks (PANs). We believe that the PAN technology available on mobile phones enables for a broad range of new collaborative applications supporting collocated work a...

The Java J2ME platform is one of the largest software platforms available, and often the only available development platform for mobile phones, which is a problem when porting C or C++ applications. The Cibyl binary translator targets this problem, translating MIPS binaries into Java bytecode to run on J2ME devices. This paper presents the optimization framework used by Cibyl to provide compact...

Mobile commerce (m-commerce) has emerged as the promising approach for driving the next wave of e-commerce. A major issue facing m-commerce is the lack of flexible, adaptable, extensible, and robust architectures for mobile and pervasive application systems for m-commerce. To address this issue, our research has explored how to employ mobile agents in developing m-commerce applications. We have...

In this paper we present an architecture based on a Java (J2SE, J2EE, J2ME and Java Card) platform supporting a secure channel from a Mobile Operator to the SIM card. This channel offers the possibility of end to end security for delivery of large data files to a GSM SIM card. Such a secure channel could be used for delivery of high value content that requires a high bandwidth channel – perhaps...

Mobile phones offer a variety of interesting and exciting applications. A mobile phone can be a communication device, an entertainment device, and a learning device. J2ME is a popular platform for mobile phone applications. In this paper we present an English-Chinese learning system which is built using J2ME and Java servlets. The system allows users, especially, those who understand Chinese, t...

Mobile Learning (M-Learning) is an electronic learning (E-learning) using mobile devices and wireless computing technology as a communication media to make learning ubiquitous and personalize. The objective of this paper is to present the design and development of a platform independent mobile learning tool (M-LT) for Structured Programming course in Universiti Teknologi PETRONAS (UTP) as a cas...

This paper evaluates the use of AspectJ, a general-purpose aspectoriented extension to Java, to provide adaptive behavior for J2ME applications in a modularized way. Our evaluation is based on the development of a simple but non-trivial dictionary application where new adaptive behavior was incrementally implemented using AspectJ. Our main contribution is to show that the AspectJ language can b...

The tuplespace programming model is based on the concepts of shared storage and synchronized retrieval. There has been much work on the design of distributed applications over tuplespaces. However, work in the use of tuplespaces in mobile distributed environments is still in its early stages. Our work proposes a system that is targeted at these environments. Our system is called MobiSpace and i...
