An important advantage of java is its portability due to its use of bytecode. However the use of bytecode allows decompilation of java programs to gain access to their source code. This makes it easier to pirate java programs, infringing their copyright. This is a disadvantage of java in comparison with programming languages that compile to native object *** watermarking is a relatively new approach to the problem of copyright protection that involves embedding ownership information in an executable program. Watermarking has been extensively researched in the context of multimedia and significant progress has been made toward the development of robust and secure techniques. In this paper we investigate a new software watermarking scheme. This is derived from signal detection theory which is used in multimedia watermarking.

The peer-to-peer (p2p) paradigm is attracting increasing attention from both the research community and software engineers, due to potential performance, reliability and scalability improvements. This paper emphasizes that JXTA can help teachers to teach p2p with java. This paper also presents an approach for performance analysis of JXTA pipes - one of the key abstractions in JXTA, which has not yet been fully evaluated. It explains how to assess a pipe and demonstrates performance results of the JXTA-java implementation. In doing so, this paper assists software developers in estimating the overall performance and scalability of JXTA, and the suitability of choosing JXTA for their specific application.

Numerous research works propose java extensions. Most of these works try to solve a precise problem and offer ad-hoc solutions to achieve their goal: language extensions, preprocessors implementation, modifications of the compiler, of the bytecode or of the virtual machine behavior. Most of this changes could be implemented in a common framework by extending a java Virtual Machine (JVM). Unfortunately, most JVM are not freely available or difficult to manage and/or to extend, and explicit use of their particular features implies a loss of portability. In this paper, we present an open java Virtual Machine (100% pure java) designed to be easily extensible (at compile-time and at run-time) by java programmers.

The JUTS system is a pseudoparallel java and J-Sim based simulation graphical tool. It deals with complex urban traffic systems from the microscopic point of view. The simulation process can be visualized, either online during its run or offline from a result file. JUTS uses XML to store maps, temporal configuration data and other description elements, that enables flexibility of use. The core of the system uses J-Sim for implementation of simulation primitives.
