Recently, Java has been spread widely. However, Java has a problem that an attacker can reconstruct Java source codes from Java classfiles. Therefore many techniques for protecting Java software have been proposed, but, quantitive security evaluations are not fully given. This paper proposes an obfuscation scheme for Java source codes by destructing the encapsulation. In addition, we propose an...

Java has rapidly gained a large user group and has become one of the most popular platforms for developing Internet applications, e.g., servlets. The Java VM is extensively used to execute servlets in web servers and Enterprise Java Beans in application servers. Due to Java’s platform independence, it has also gained large acceptance in the opensource community. This has lead to the development...

Bytecode rewriting is a portable way of altering Java’s behavior by changing Java classes themselves as they are loaded. This mechanism allows us to modify the semantics of Java while making no changes to the Java virtual machine itself. While this gives us portability and power, there are numerous pitfalls, mostly stemming from the limitations imposed upon Java bytecode by the Java virtual mac...

Java applications are becoming increasingly popular for embedded devices, like cellphones or personal digital assistants. The reasons for this success are the properties of the Java language and environment: portability, type safety, automatic memory management and easy network downloading of code. In this context, writing a complete operating system in Java is interesting because the whole exe...

A computer language Java is a possible solution for the standardization of accelerator software to improve software productivity and realize common user interface. In this paper, JPP: a particle tracking code written in Java is presented as an example of Java application for accelerators. We discuss the advantage and disadvantage of developing scientific software with Java and investigate the p...

Increasing interest is being shown in the use of Java for large scale or Grande applications. This new use of Java places speciic demands on the Java execution environments that could be tested and compared using a standard benchmark suite. We describe the design and implementation of such a suite, paying particular attention to Java-speciic issues. Sample results are presented for a number of ...

This paper presents language interoperability issues appearing in order to implement support for the BETA language in the Java-based Eclipse integrated development environment. One of the challenges is to implement plug-ins in BETA and be able to load them in Eclipse. In order to do this, some form of language interoperability between Java and BETA is required. The first approach is to use the ...
