Commercial systems are developed with a huge range of performance requirements and we are concerned in this article with the small number of systems where absolute maximum performance is demanded either in terms of execution speed or available memory. We'll discuss the role of bespoke ...
Faced with the demands of mission-critical applications, many enterprise developers have pushed the Java language and the Java Virtual Machine (JVM) to the limit. The most common issue seen in transactional environments is achieving predictable response time or latency - in other words...
Parallel programming in Java is becoming easier with tools such as the fork/join framework, Pervasive DataRush, Terracotta, and Hadoop. This article gives a high-level description of each approach, pointing you in the right direction to begin writing parallel applications of your own. ...
An applet, a Java program that runs in a browser, often has to access the client resources. However, the security manager prevents an applet from accessing client resources. To access client resources, the applet has to have the proper permission. With this permission the applet can th...
As a software journalist, there are times when certain vendors will shut the door on reporting opportunities that might represent too much of an "inside view" of their technology or their organization. I've been to more developer events than I can remember where I've been handed a larg...
Applications that have high performance as a quality goal would motivate a programmer to design and build them as multithreaded apps. The Java programming environment provides for parallel execution of logic by using threads. However, this is at a lower level and provides limited capab...
Open source software, while not synonymous with Java, may often be seamlessly integrated with Java code to produce a versatile synthesis that makes developers' lives much easier. In recent years, developers have taken some open source dynamic languages, commonly referred to as 'scripti...
A standard from OASIS called Web Services for Remote Portlets (WSRP) is used so portlets can be decoupled from a portal. In part one (JDJ, Volume. 13, issue 3) of this article, we introduced the relevant standards and specifications and then demonstrated WSRP's capabilities by consumin...
A fast-moving Comet is about to impact the Internet. When it hits, it will wipe away the architecture flaws we have lived with for the past 15 years and allow a new World Wide Web to evolve. This new Web will include applications that are instantly on and always on, applications that a...
