Dustin Marx Introduces JAX-RS with Jersey (and GlassFish and NetBeans)
Our lead Java Today story is JAX-RS with Jersey: An Introduction, by Dustin Marx. I found this intersting, because a few weeks ago I spent some time studing Jersey, as I thought about resurrecting an old project of mine, and redeploying it using GlassFish, Jersey, and other current Java technologies.
Dustin begins his introduction with:
The JAX-RS (JSR 311: The Java API for RESTful Web Services) specification provides a standardized Java-based approach to implementing REST-style web services. Jersey is the reference implementation of JAX-RS and I provide a brief introduction to JAX-RS via Jersey in this blog post. Although Jersey doesn't require the use of GlassFish, I use Jersey in conjunction with GlassFish v3 in this post.
Dustin then proceeds, step-by-step, first covering how to install GlassFish Version 3 on a Windows machine, set the necessary environment variables, and bring up the GlassFish admin console:
His example REST application is MovieOfTheDay.java, a 127-line class with the requisite JAX-RS annotations. Dustin was also working with NetBeans 6.8, and presents the web.xml file that NetBeans generated when he added the necessary JAX-RS and Jersey jar files to his project's libraries. He then goes through the remaining steps to bring the application live, providing screen shots.
JAX-RS with Jersey: An Introduction concludes with:
The process of deploying a JAX-RS-based web service using Jersey and GlassFish is relatively straightforward. All I really needed was access to the JAX-RS and Jersey JARs, the properly annotated Java class, and the short web.xml file that allowed Jersey to be used as a servlet. This blog post has attempted to show the basic steps involved with writing a simple JAX-RS-annotated class, deploying it to GlassFish, and taking advantage of Jersey's implementation of JAX-RS.

In today's Weblogs, I decided to check in on Geerjan Wielenga to see if he's found any interesting new YANPAs (Yet Another NetBeans Platform Application) recently. Yes, he has. So, I posted YANPAs: They're Everywhere!:
Where I live (Connecticut, US), a popular bumper sticker is "Motorcycles Are Everywhere!" That's what I was reminded of as I surveyed the past week's posts by Geerjan Wielenga, and saw that he has discovered several interesting YANPAs (Yet Another NetBeans Platform Application, as he sometimes calls them). It really begins to appear that, like motorcycles, YANPAs are indeed everywhere! Furthermore, you find YANPAs even in the coldest months! ...
Santiago Pericas-Geertsen is Exploring Hypermedia Support in Jersey:
During the last few weeks, Marc H., Paul S. and myself have been exploring some ideas to support Hypermedia in Jersey. The outcome of this investigation is an experimental implementation that is available in Jersey's trunk (module version 1.2-SNAPSHOT). Exactly what it means to support hypermedia is still an area of research, and some other implementations of JAX-RS (notably RESTfulie) have also proposed APIs for it. The REST architectural style, as defined by Roy Fielding in his thesis, is characterized by four constraints...
Juliano Viana posted his first java.net blog, Making Apache Wicket even more designer friendly :
Hi, my name is Juliano Viana, I'm a software consultant and developer based in Brazil, and I've been honored with the opportunity to blog in Java.net! Hope I can contribute something to this great community resource. For my first blog post at Java.net I've choosen to write about my web framework of choice, Apache Wicket. A designer and developer friendly framework Wicket is a great web framework - it allows the creation of complex web interfaces, complete with fancy ajax effects, in a simple and straigthforward way...

Our current Spotlight is the Oracle announcement about Kenai.com: "Our plan is to shut down kenai.com and focus our efforts on java.net as the hosted development community. We are in the process of migrating java.net to the kenai technology. This means that any project currently hosted on kenai.com will be able to continue as you are on java.net. We are still working out the technical details, but the goal is to make this migration as seamless as possible for the current kenai.com projects..."
