REST Web services
REST (representational state transfer) is an approach for getting content from a website by reading a designated webpage that contains an XML (Extensible Markup Language) file that describes and includes the desired content. A basic use case for it would be an online publisher making available syndicated content. Subscribers would need only to know the URL (Uniform Resource Locator) for the page where the XML file was located, read it with a Web browser, interpret the content data, and reformat and use it appropriately. The fundamental difference between REST Web services and document-style Web services is how the service consumer knows what to expect out of the service. Web services have contracts, defined in WSDL. Since Web services focus on the service, rather than on the resource, the consumer has clear visibility into the behavior of the various operations of the service, whereas in RESTful resource-oriented perspective, we have visibility into the resources, but the behavior is implicit, since there is no contract that governs the behavior of each URI-identified resource.

Java APIs to bridge the gap between today and future development efforts
09 Nov 2015
Feature - At JavaOne 2015, a big topic of conversation was APIs and API development. In the IBM keynote, the promise was that an evolutionary approach to API development will help modern day developers pass the torch to those doing development in the future.
When loose coupling and SOA style software layering doesn't make sense
15 Jun 2015
Feature - Loose coupling and adding in SOA style layers don't make sense unless an application is going to be distributed. If enterprise wide distribution isn't in your application's future, stop adding in extra complexity, and collapse those layers into something...
The challenge of managing distributed data can only be solved with NoSQL solutions
18 May 2015
Feature - Managing data over large geographic areas where latency and reliability problems exist is a major challenge for relational databases, but fortunately, NoSQL databases are solving the problem of managing distributed data.
Establishing a coherent API for the Internet of Things (IoT)
11 May 2015
Feature - The rapid growth of smart devices is inspiring many developers to create applications for home monitoring, health, and other services. But these applications are dependent on early adopters that actually buy and install hardware. Read on to find out how...
Where are the REST alternatives for real-time applications?
06 Apr 2015
Feature - Enterprise developers face number of challenges in creating frameworks for building scalable real-time applications that power modern apps like the cars moving in Uber. Read on to find out how new protocols and automatically synchronized database...
Can a pattern become an anti-pattern? How to avoid the loose coupling mistake
15 Jan 2015
Feature - Nobody is debating the benefits of loose-coupling, but far too many SOA architects take the practice too far. Make sure you know when loose-coupling makes sense, and more importantly, when it doesn't.
Creating pages based on a JSF template: Using the Facelets ui:define tag
20 Jul 2014
Tutorial - What do you do once you've set up a handsome page template using the Facelets functions that come with JSF 2.x? Well, you start creating new pages, meshing those ui:define tags in with ui:composition and ui:insert. It's easier than it sounds, trust me.
Conquering the challenge of integrating JAX-RS (REST) with OSGi modularity
06 May 2014
Feature - OSGi and REST based web services are two incredibly popular technologies that have evolved separately over the past few years. But now developers are tackling the challenge of bringing these two technologies together. Here's how they are making that...
Why API delivery will trump application delivery in importance in 2014
05 Jan 2014
Feature - Delivering software is important, but in this age of social media and networked infrastructure, allowing various pieces of software to integrate seamlessly is of heightened importance. This makes the development of externally facing client APIs more...
From WebSockets to HTML5: What's new and what's next for Java EE 7
01 Jan 2014
Feature - What's new with Java EE 7? In this article we talk with Peter Pilgrim, the author of the Java EE 7 Developer Handbook, about the key new elements of Java EE 7 that developers need to learn in order to stay current with modern development trends.
