When someone in a corporate boardroom decides what their IT strategy is going to be, it isn't based on what language or software architecture they will use, but on how a system can provide value to their business. Very few organizations buy their hardware and OS first, and then tool up...

In concurrent programming, exclusion refers to any technique that dynamically locks certain blocks of code so multiple threads can't corrupt their shared resources in ways that can cause integrity problems. In Java, exclusion has meant using the synchronized keyword against a method or...
The creation and popularity of Web Services are growing rapidly in every industry. With this continued growth, more and more programmers find themselves writing code that, even if it's not currently packaged as a Web Service, will eventually be exposed as one.
Open Source Business Intelligence software is finally coming into its own, with three major players coming to the fore: JasperReports, Pentaho, and BIRT (Business Intelligence and reporting tools). Business Intelligence technology comprises solutions for delivering enterprise data in t...

Most non-trivial applications involve high degrees of concurrency and many layers of abstraction. Concurrency is associated with resource contention and an increase in deadlock conditions. The multiple layers of abstraction make it more difficult to isolate and fix the deadlock conditi...
Today's web developers have a lot of choices when it comes to web application platforms. Among them, Java EE has always stood out as a 'scalable' solution -- it may not be the easiest platform to prototype a web site, but it protects your software investment over longer terms. For inst...
