Knowledge Discovery Metamodel (KDM) is publicly available specification from the Object Management Group (OMG). KDM is a common intermediate representation for existing software systems and their operating environments, that defines common metadata required for deep semantic integration of Application Lifecycle Management tools. KDM was designed as the OMG's foundation for software modernization, IT portfolio management and software assurance. KDM uses OMG's Meta-Object Facility to define an XMI interchange format between tools that work with existing software as well as an abstract interface (API) for the next-generation assurance and modernization tools. KDM standardizes existing approaches to knowledge discovery in software engineering artifacts, also known as software mining.

WindowBuilder Pro (also known as just WindowBuilder) is a powerful and easy to use bi-directional Java GUI designer. It is composed of SWT Designer, Swing Designer and GWT Designer and makes it very easy to create Java GUI applications without spending a lot of time writing code to display simple forms. With WindowBuilder Pro you can create complicated windows in minutes. Use the visual designer and Java code will be generated for you. You can easily add controls using drag-and-drop, add event handlers to your controls, change various properties of controls using a property editor, internationalize your app and much more.

Eclipse Rich Client Platform has come a looong way since it was first introduced (and used in Eclipse IDE). The new Eclipse RAP (Rich Application Platform) is also becoming more and more attractive for deploying existing or new Eclipse RCP applications to the web. One of my the projects I'm working on is developed on top of Eclipse RCP. It uses additional plugins such as EMF (Eclipse Modeling Framework) including EMF Editor UI, Teneo (EMF Persistence for Relational Databases), and Hibernate. After some work, I managed to run the whole application on both Eclipse RCP (desktop) and Eclipse RAP (web-based). See the screenshots for proof. Thanks to the recently released EMF Support for RAP I don't have to let go any of the nice EMF generated editor UIs for the web-based RAP version. What's amazing is how little the work I have to do to port the RCP app to RAP. The changes I needed to do is not changing code, but juggling dependencies to plugins and/or packages. Also creating a few platform-specific plugins (different based on whether I deploy on RCP or RAP).

" In general when people think about running a Java based application server with Apache as front-end they almost always think about using mod_jk to proxy to Glassfish, but you can also use mod_proxy quite effectively. If you are wanting to proxy from a HTTPS Apache to a HTTP Glassfish then this article describes how you can do that. "

Akka is the platform for the next generation event-driven, scalable and fault-tolerant architectures on the JVM We believe that writing correct concurrent, fault-tolerant and scalable applications is too hard. Most of the time it's because we are using the wrong tools and the wrong level of abstraction. Akka is here to change that. Using the Actor Model together with Software Transactional Memory we raise the abstraction level and provide a better platform to build correct concurrent and scalable applications. For fault-tolerance we adopt the "Let it crash" / "Embrace failure" model which have been used with great success in the telecom industry to build applications that self-heal, systems that never stop. Actors also provides the abstraction for transparent distribution and the basis for truly scalable and fault-tolerant applications. Akka is Open Source and available under the Apache 2 License.

"Scalaz is a library written in the Scala Programming Language. The intention of Scalaz is to include general functions that are not currently available in the core Scala API. The scalaz-core module depends only on the core Scala API and the core Java 2 Standard Edition API. Scalaz is released under a BSD open source licence making it compatible with the licence of the Scala project. Scalaz 6.0.1 was released in June 2011, targeting Scala 2.8.1 and 2.9.0.1. "

Modeling is supposed to be one of the most important activities in any software development process. At least this is the general understanding within the software engineering research community. However, in the day-to-day practice, modeling is usually regarded as, basically, a waste of time.

"The general architecture of Jackrabbit can be described in three Layers: A Content Application Layer, an API Layer and a Content Repository Implementation Layer."

"This page will be used to show solutions to common problems related to Apache Jackrabbit and the JCR API. These examples shouldn't be considered Best Practices - general error checking and exception handling have been omitted to keep the example code simple. "

The Compact Namespace and Node Type Definition (CND) notation provides a compact standardized syntax for defining node types and making namespace declarations. The notation is intended both for documentation and for programmatically registering node types (if you are unfamiliar with JCR node types, you may want to read the general Node Types section first).

Scala is a general purpose programming language designed to express common programming patterns in a concise, elegant, and type-safe way. It smoothly integrates features of object-oriented and functional languages. It is also fully interoperable with Java

"Clojure is a dynamic programming language that targets the Java Virtual Machine (and the CLR ). It is designed to be a general-purpose language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming. Clojure is a compiled language - it compiles directly to JVM bytecode, yet remains completely dynamic. Every feature supported by Clojure is supported at runtime. Clojure provides easy access to the Java frameworks, with optional type hints and type inference, to ensure that calls to Java can avoid reflection. Clojure is a dialect of Lisp, and shares with Lisp the code-as-data philosophy and a powerful macro system. Clojure is predominantly a functional programming language, and features a rich set of immutable, persistent data structures. When mutable state is needed, Clojure offers a software transactional memory system and reactive Agent system that ensure clean, correct, multithreaded designs. I hope you find Clojure's combination of facilities elegant, powerful, practical and fun to use."

Free universal java GC log viewer for parsing JVM garbage collection logs. Generates WOW graphs & AHA metrics. Memory tunning, long GC pause, memory leak, OutOfMemoryError debugging, verbose java gc analysis all made easy.

The default EMF UML2 repository implementation was changed from UML2 1.x to UML2 2.x, in order to support the most current versions of the MagicDraw and Rational tools. Due to conflicting dependencies in the uml libraries, both implementations could not be supported at the same time.

"Essential is a project to create a workbench for applying Model Driven Development (MDD). The workbench allows to experiment with models, metamodels, templates and transformations in an integrated environment. The main focus is to provide a declarative environment oriented to prototyping and evolving custom DSL and MDD tools in a quick and clean way. Motivation for a new tool Essential.Meta. DSL for Metamodelling Modelling with Essential StringTemplate, the template engine"

" Xtext has been released as a part of the Eclipse Galileo release train on June 24th, 2009. Xtext is a framework for building DLSs (domain specific languages). In fact, it can be seen as a DSL for defining DSLs. In this article, we will develop a small DSL for defining entities."
