"The NetKernel Resource Oriented Computing (ROC) platform separates architecture from code. With ROC you can compose your architectural design independently from implementation code.
By keeping the details of code separate from high-level information architecture you gain:
freedom of choice in implementation language
rapid click-fit compositional development
long-term evolvable solutions
Threading and scheduling is managed by the microkernel so your code execution is efficiently optimised with linear scaling on multi-core without the need to learn new languages.
Something brand-new also comes from separating architecture and code. NetKernel provides system-wide caching of every area of your system. For free. No configuration.
NetKernel learns what information is reusable and reuses it. This makes NetKernel systems fast. Very fast."

As Eclipse plug-in and Rich Client Platform developers, we face unique challenges in how we structure and execute our unit tests. In this article, I suggest an approach to unit testing based on Eclipse fragments that can help us overcome these challenges. If you find yourself frustrated with your current plug-in testing options, read on!
But before going into detail on a fragment based solution, let's examine the current approaches and the pros and cons associated with each. The first approach is the one most of us start with as we learn the ropes of plug-in development: placing all code in a single plug-in.

Hibernate Tutorial. In this hibernate tutorial, we will learn basics of hibernate, inheritance mapping, collection mapping, component mapping, HQL, HCQL, Named Query, Caching and Integration of Hibernate with other frameworks.
Java technology is widely used currently. Let's start learning of java from basic questions like what is java, where it is used, what type of applications are created in java and why use java? What is Java? Java is a programming language and a platform.
There is given many features of java. They are also called java buzzwords. 1.Simple 2.Object-oriented 3.Platform independent 4.Secured 5.Robust 6.Architecture neutral 7.Portable 8.Dynamic 9.Interpreted 10.High Performance 11.Multithreaded 12.Distributed Simple Java is simple in the sense that: syntax is based on C++ (so easier for programmers to learn it after C++).

Spring Security is a powerful and highly customizable authentication and access-control framework. It is the de-facto standard for securing Spring-based applications
Spring Security is one of the most mature and widely used Spring projects. Founded in 2003 and actively maintained by SpringSource since, today it is used to secure numerous demanding environments including government agencies, military applications and central banks. It is released under an Apache 2.0 license so you can confidently use it in your projects.
Spring Security is also easy to learn, deploy and manage. Our dedicated security namespace provides directives for most common operations, allowing complete application security in just a few lines of XML. We also offer complete tooling integration in SpringSource Tool Suite, plus our Spring Roo rapid application development framework. The Spring Community Forum and SpringSource offer a variety of free and paid support services. Spring Security is also integrated with many other Spring technologies, including Spring Web Flow, Spring Web Services, SpringSource Enterprise, SpringSource Application Management Suite and SpringSource tc Server.
"Executing external processes from Java is a well-known problem area. It is inheriently platform dependent and requires the developer to know and test for platform specific behaviors, for example using cmd.exe on Windows or limited buffer sizes causing deadlocks. The JRE support for this is very limited, albeit better with the new Java SE 1.5 ProcessBuilder class.
Reliably executing external processes can also require knowledge of the environment variables before or after the command is executed. In J2SE 1.1-1.4 there is not support for this, since the method, System.getenv(), for retriving environment variables is deprecated.
There are currently several different libraries that for their own purposes have implemented frameworks around Runtime.exec() to handle the various issues outlined above. The proposed project should aim at coordinating and learning from these initatives to create and maintain a simple, reusable and well-tested package. Since some of the more problematic platforms are not readily available, it is my hope that the broad Apache community can be a great help."
Atmosphere is a POJO based framework using Inversion of Control (IoC) to bring push/Comet and Websocket to the masses! Finally a framework which can run on any Java based Web Server, including Tomcat, Jetty, GlassFish, Weblogic, Grizzly, JBossWeb and JBoss, Resin, etc. without having to learn how Comet or WebSocket support has been differently implemented by all those Containers. The Atmosphere Framework has both client (JQuery PlugIn) and server components.
Servlet 3.0 is supported along with framework like Jersey (natively), GWT (natively), Wicket, Guice, Spring etc. and programming language like JRuby, Gr oovy and Scala. We also support massive scalability with our Cluster plugin architecture (JGroups, JMS/ActiveMQ, Redis, XMPP,i etc.)
Jettison is a collection of Java APIs (like STaX and DOM) which read and write JSON. This allows nearly transparent enablement of JSON based web services in services frameworks like CXF or XML serialization frameworks like XStream.
There are currently two included conventions for mapping JSON to XML. The first, is BadgerFish which implements the full XML infoset in JSON using various techniques. The second, is called the "mapped" convention. It allows you to manually map XML namespaces to JSON element prefixes.
Jettison was developed for usage in XFire and CXF to enable JSON based services. Later it also found its place in Java object serialization with XStream
