Service Discovery is an essential aspect of service orientated architecture because it avoids early binding of clients to particular service instances. In this article, Jan Algermissen explains the need for discovery of RESTful services, and explains how the existing Domain Name Service (DNS) standard can be used as a widely-deployed and scalable solution.
Most web service developers rely on a data binding conversion layer within a web service to work directly with data structures in their programming language of choice - but this causes a number of problems. In the first of a series of articles that look at these problems, Dennis Sosnoski starts at the most basic level, looking at simple data types and the issues that arise from mapping them.
Kjell-Sverre and Jean-Jacques revisit the principles of contract design focusing on the concept of compatible contract based on XML, XML Schema and WSDL extensibility to foster service reuse and complement Governance. The article includes a novel approach to manage message types in relation to an enterprise data model.
Smooks is best known for its transformation capabilities, but in this article Tom Fennelly describes how you can also use it for structured event streaming. 17
Platforms need interoperability. In this article Flex interoperability with JSON and XML is explored including direct mapping to chart and grid components. 2
In this article, Bryon Jacob and Chris Berry continue their description of AtomServer, their implementation of a full-fledged Atom Store based on Apache Abdera.
In this article, Ian Robinson discusses how consumer-driven contracts (stories for services and unit tests exchanged between service development streams) can strengthen the SOA development lifecycle. 2
Thin client paradigm characterized by web applications is a kludge that needs to be repudiated. Old compromises are no longer needed and it's time to move the presentation tier to where it belongs. 24
In this article, Bryon Jacob and Chris Berry introduce AtomServer, their implementation of a full-fledged Atom Store based on Apache Abdera, which is now available as open source. 8
This article, based on a chapter from the book "Service Oriented Architecture Demystified", discusses the benefits of applying SOA to heterogenous environments in the healthcare domain.
InfoQ spoke to the lead developers of the most important open source Java Web-services stacks about their design goals, standards, data binding, XML, interoperability, REST support, and maturity. 12
Today, almost every modern application consumes or produces XML. Stefan Bodewig explains the challenges in testing XML-based applications, and shows how to use the XMLUnit Java Framework to do so. 8
