Cloud-platforms.pdf (application/pdf Object) A Jersey POJOMapping Client/Server Example. JAX-RS is the specification that describes how to build RESTful interfaces in a Java EE environment.
Jersey is the reference implementation of that spec, and, like many implementations, offers features above and beyond what spec does. One feature that I’ve been working with recently is the POJOMapping feature, which makes writing services and clients much easier, as well as typesafe. In a nutshell, what this feature allows you to do is deal with actual model classes in your service with little to no regard for their serialization and deserialization.
That’s a huge boon, as dealing with XML and JSON isn’t always pretty, and really isn’t what we’re wanting to do with our service. To see how this works, we’ll develop a simple service and a client to interact with. It’s a POJO in every sense of the word, so it’s pretty boring. This is a very basic JAX-RS resource. Handle the serialization of the `Cluster ` instances to JSON, XML, etc., but we’re not. Play Framework. History Play was created by software developer Guillaume Bort, while working at Zenexity. Although the early releases are no longer available online, there is evidence of Play existing as far back as May 2007. In 2007 pre-release versions of the project were available to download from Zenexity's website. Play 1.1 was released in November 2010 after a move from Launchpad to GitHub.
It included a migration from Apache MINA to JBoss Netty, Scala support, native GlassFish container, an asynchronous web services library, OAuth support, HTTPS support and other features. Play 1.2 was released in April 2011. It included dependency management with Apache Ivy, support for WebSocket, integrated database migration (reversion is not implemented yet), a switch to the H2 database and other features. Sadek Drobi joined Guillaume Bort late 2011 to create Play 2.0 which was released on March 13, 2012 in conjunction with Typesafe Stack 2.0. Motivation Components

W ogóle jakiś taki grzeczny - zdecydowanie za mało płacze. Żonka uśmiechnięta i cała w skowronkach, a starszaki - Iwetka i Patryś - rozkochane w braciszku. Sielanka, że nic tylko mieć kolejne dzieci.

Warto się z nim zapoznać, bo jest, jak to się wyrażono na stronie 2: Part Three: New Features in EJB 3.1. This series of articles is a preview of the changes the EJB 3.1 expert group is working on for the next version of the Java EE specification.
The idea is to give you a head's up on the changes as well as gather your feedback early so the expert group has the best chance of getting it right. EJB 3.0 brought simplicity to Java EE 5 by moving away from a heavyweight programming model. EJB 3.1 aims to build on those successes by moving further down the path of simplicity as well as adding a handful of much-needed features. In each article in this series, I will let you know about the progress made by the expert group.
In the first two articles of this series, I covered a few of the earliest discussed features - optional interfaces for Session beans, Singleton beans, EJB Timer Service enhancements and simplified packaging. - The Java EE 6 Tutorial. How to Access EJBs. Setting JNDI Properties If the client is collocated with the target, the client exists within the same application as the target, or the target exists within its parent, then you do not need a JNDI properties file.
Else, you must initialize your JNDI properties either within a jndi.properties file, in the system properties, or within your implementation, before the JNDI call. The following sections discuss these three options: To specify credentials within the JNDI properties, see "Specifying Credentials in EJB Clients". No JNDI Properties A servlet that is collocated with the target bean automatically accesses the JNDI properties for the node. //Get the Initial Context for the JNDI lookup for a local EJB InitialContext ic = new InitialContext(); //Retrieve the Home interface using JNDI lookup Object helloObject = ic.lookup("java:comp/env/ejb/HelloBean"); This is also true if the target bean is in the same application or an application that has been deployed as this application's parent.
