The Java Virtual Machine (JVM) provides a high degree of platform independence, but being an interpreter, Java has a poor system performance. New compiler techniques and Java processors will gradually improve the performance of Java, but despite these developments, Java is still far from real-time. We propose the Communicating Java Threads (CJT) model, which eliminates several shortcomings, su...

This article looks at the advantages and disadvantages of using Java and Java 3D for games programming. It assumes the reader is familiar with Java, but presents short overviews of gaming, the low-level APIs OpenGL and DirectX, and Java 3D. No programming examples are included here, although links to online code are supplied. 1. Background to Gaming Giving a definition for ‘computer game’ is pr...

We present a design and an implementation of the MPI (Message Passing Interface) standard in the Java language, called JMPP (Java Message Passing Package). Our implementation is not an interface from the Java language to existing MPI libraries. Rather, the implementation is completely coded in Java. Therefore, JMPP maintains the platform-independence property of Java. Furthermore, JMPP enhances...

This paper describes the motivations and strategies behind our group’s efforts to integrate the Tcl and Java programming languages. From the Java perspective, we wish to create a powerful scripting solution for Java applications and operating environments. From the Tcl perspective, we want to allow for cross-platform Tcl extensions and leverage the useful features and user community Java has to...

Scaling web applications by adding processors is important as the number of users increase by the day, database size is on the rise which results in huge volume of work. The complication that exists in scaling does not just depend on increasing the count of new processors as the paradox also exists in extensive scaling of Java applications. This limitation is bounded specifically to Java progra...

In this paper we report on the features of the Java Commodity Grid Kit. The Java CoG Kit provides middleware for accessing Grid functionality from the Java framework. Java CoG Kit middleware is general enough to design a variety of advanced Grid applications with quite different user requirements. Access to the Grid is established via Globus Toolkit protocols, allowing the Java CoG Kit to commu...

ABSTRACT Java has become one of the most popular languages for network applications. The main drawback of Java is concerned with the execution speed due to interpreted execution. We implemented a translation system that converts Java bytecode to X86 assembly code. The main approach of our translation system is that objects are still created and manipulated inside the (run-time) Java virtual mac...
