  • Dynamic Routing Using Spring framework and AOP

    Vigil Bose shows how a business transaction can trigger business events dynamically for subsystem processing. The examples shown in this article uses Spring framework 2.0 and Spring AOP effectively to decouple the business service from the subsystem processing functionality.

  • Aaron Erickson on LINQ and i4o

    Aaron Erickson introduces his new LINQ extension Indexes for Objects (i4o). Indexes for Objects allows for fast lookup against in-memory collections while retaining the LINQ syntax and semantics. He also discusses how expression trees interact with LINQ and how they can be leveraged in other scenarios.

  • Service Firewall Pattern

    How can you protect a service against detect malicious incoming messages and prevent information disclosure on outgoing messages? In this sample chapter from Arnon Rotem-Gal-Oz' in-progress book SOA Patterns, Arnon explains how to use a Service Firewall to intercept incoming and outgoing messages and inspect them in a dedicated software component or hardware.

  • Service Oriented Architecture Governance: The Basics

    In this article, MomentumSI's Ed Vazquez explains the basics of SOA governance, with an explicit focus on the need for a holistic SOA governance model, shared governance principles and the difference between (and the need for both) tactical and strategic efforts.

  • Unit-Testing XML

    There are many occasions where software creates XML output: XML documents are used for data interchange between different applications, web application create (X)HTML output or respond to AJAX requests with XML, and this has to be tested as much as anything else. In this article, Stefan Bodewig explains how to perform those tests with the XMLUnit framework he has co-authored.

  • "Real Options" Underlie Agile Practices

    Whether we realise it or not, "freedom to choose" is a principle underlying many Agile practices. By avoiding early commitments, we gain flexibility in the choices we make later. In this article, Chris Matts and Olav Maassen propose that an understanding of "Real Options" allows us to develop and refine new agile practices and take agile in directions it hasn't gone before.

  • Interview: Jezz Santos about Software Factories

    InfoQ had a chance to talk to Jezz Santos, a trusted expert advisor for the Web Service Software Factory and the creator of one of the world’s first implementations of a software factory (the EFx Factory), which demonstrates some of the advanced features of a future generation of software factories to come from Microsoft. We questioned him on his view of the Microsoft Software Factory Initiative.

  • Using Java to Crack Office 2007

    Office file manipulation used to be difficult, but since Office 2007, Word, Excel and Powerpoint files can be read and written without anything more complicated than the native JDK itself because Office 2007 documents are now nothing more than ZIP files of XML documents. Ted Neward demonstrates this in action.

  • Interview and Book Excerpt: RESTful Web Services

    Today, InfoQ publishes a sample chapter from RESTful Web Services, a book authored by Leonard Richardson and Sam Ruby. The book covers the principles of the REST style, and explains how to build RESTful applications using Java, Ruby, and Python. InfoQ's Stefan Tilkov had a chance to talk to the authors about their motivations for writing this book and their views on REST and Web services.

  • Implementing Exceptions in SOA

    In this InfoQ article, Boris Lublinsky highlights the problems with exception handling in SOA, and suggests a SOA-based solution: a logging service that accepts all logging requests, stores and forwards them to an exception resolution service, which is responsible for enforcing rules about exception resolution, a notification service, an exceptions/logging portal, and service management.

  • Case Study: Composite Applications at Safeco

    A case study about how motor vehicle insurance records company Safeco used SOA approahes, SCA, BPEL, and composite application approaches to reuse legacy code, enable runtime modifiability thanks to decoupling, Java and .NET interoperability, and the ability to deliver a complex solution integrating over 5 systems in less than 8 weeks with a small team.

  • Case study: A new approach to integrating architectures post-merger at Lawson

    The merger of Lawson and Intentia in 2006 left developers with an important problem to solve - the integration and presentation of legacy applications and business services that are constructed in Java, .NET, and other technologies. This case study looks under the hood at the new architecture at Lawson and how they got there.
