  • From Java to Ruby: Strategies for Pilots

    The Ruby on Rails revolution has been led by developers. Convincing management takes another kind of persuasion. A manager needs to understand the risks of adopting Ruby, the risks of snubbing mainstream languages like Java--even for one project--and the overall technical landscape of Ruby's capabilities.

  • ESB Roundup Part One: Defining the ESB

    A healthy debate has arisen in the SOA community around the Enterprise Service Bus. Is an ESB needed? What is the best definition of an ESB? When should an ESB be deployed? What is its role in SOA? In the first part of a series, InfoQ explores this vital topic.

  • Book Review: Agile Java Development with Spring, Hibernate and Eclipse.

    Anil Hemrajani relates Agile practices to Java and several open source toolsets (Spring, Hibernate, Eclipse) designed to make Java development simpler. It's a high level overview of some free technologies used in web app development. Matt Morton liked this book, recommending it to technical managers and intermediate developers in small Java web development shops.

  • Delivering Java Apps on Fedora Core

    Fedora Core 4 was the first release to include a a lot of code written in Java. gcj aims to implement a complete system, compatible with Java, centered around an ahead-of-time compiler. It has a cleanroom class library based on GNU Classpath, and a built-in interpreter. The compiler can compile Java source files, class files, or even entire jar files to object code.

  • Real-World Rule Engines

    For many developers, rule engines are buzzwords, or black boxes on an architectural diagram: something to be feared or admired from afar, but not understood. In this article, Geoffrey Wiseman shares his practical experience with rule engines and with Drools in particular to support in-market solutions for financial services.

  • Evolutionary integration with ESBs

    ESB Programming experts provide simple working examples and clearly communicated ideas and patterns using the open source Mule ESB tool set. These examples provide both working code as well as suggest a methodology of evolutionary integration which can be used to dramatically simplify and accelerate SOA integration.
