Activeresource. Part 1: Introduction to Jersey--a Standard, Open Source REST Implementation. By Julien Dubois, June 2010 Introduction This article is part 1 of a four-part series. It briefly introduces basic Representational State Transfer (REST) principles, and then quickly leaves theory in order to build a real-life sample application. We will use the new Java Platform, Enterprise Edition (Java EE) 6 standard to create a classical JavaServer Faces application, and we will study why this application does not follow the REST principles.
Using NetBeans, we will then add a second, Jersey-based view on top of our application, which will run in parallel with the JavaServer Faces front end. We will then compare both approaches to determine their pros and cons. In part 2 of this series, we will look at JQuery, a popular JavaScript framework. Note: This article was written and tested using NetBeans IDE 6.8. REST and Jersey REST is an architectural style defined by Roy T. An HTTP GET request to receive a resource An HTTP POST request to create a new resource Testing the REST Application. REST Anti-Patterns. When people start trying out REST, they usually start looking around for examples – and not only find a lot of examples that claim to be “RESTful”, or are labeled as a “REST API”, but also dig up a lot of discussions about why a specific service that claims to do REST actually fails to do so.
Why does this happen? HTTP is nothing new, but it has been applied in a wide variety of ways. Some of them were in line with the ideas the Web’s designers had in mind, but many were not. Applying REST principles to your HTTP applications, whether you build them for human consumption, for use by another program, or both, means that you do the exact opposite: You try to use the Web “correctly”, or if you object to the idea that one is “right” and one is “wrong”: in a RESTful way. For many, this is indeed a very new approach. As with any new approach, it helps to be aware of some common patterns. Let’s start with a quick list of anti-patterns I’ve managed to come up with: A Brief Introduction to REST.
You may or may not be aware that there is debate going on about the “right” way to implement heterogeneous application-to-application communication: While the current mainstream clearly focuses on web services based on SOAP, WSDL and the WS-* specification universe, a small, but very vocal minority claims there’s a better way: REST, short for REpresentational State Transfer. In this article, I will try to provide a pragmatic introduction to REST and RESTful HTTP application integration without digressing into this debate. I will go into more detail while explaining those aspects that, in my experience, cause the most discussion when someone is exposed to this approach for the first time. Key REST principles Most introductions to REST start with the formal definition and background. Give every “thing” an ID I’m using the term “thing” here instead of the formally correct “resource” because this is such a simple principle that it shouldn’t be hidden behind terminology.
Link things together. Sinatra. Representational State Transfer (REST) Resource Guide. This SearchSOA.com learning guide will delve into the basics of representational state transfer (REST), its progress in various app dev tooling platforms and its uses inside of a service-oriented architecture (SOA). REST has now moved from a bleeding edge developmental style to one with widespread vendor and open source support. Whether you are a developer, architect, manager or executive, RESTful Web services are likely to become a common occurrence in your applications portfolio. REST Basics REST Tooling Support REST and SOA SearchSOA.com Tutorials Fielding describes REST as an architectural style that leverages the modern Web, adding "REST emphasizes scalability of component interactions, generality of interfaces, independent deployment of components, and intermediary components to reduce interaction latency, enforce security, and encapsulate legacy systems.
