"Apache Tuscany simplifies the task of developing SOA solutions by providing a comprehensive infrastructure for SOA development and management that is based on Service Component Architecture (SCA) standard. With SCA as it's foundation, Tuscany offers solution developers the following advantages: Provides a model for creating composite applications by defining the services in the fabric and their relationships with one another. The services can be implemented in any technology. Enables service developers to create reusable services that only contain business logic. Protocols are pushed out of business logic and are handled through pluggable bindings. This lowers development cost. Applications can easily adapt to infrastructure changes without recoding since protocols are handled via pluggable bindings and quality of services (transaction, security) are handled declaratively. Existing applications can work with new SCA compositions. This allows for incremental growth towards a more flexible architecture, outsourcing or providing services to others. In addition, Tuscany is integrated with various technologies and offers: a wide range of bindings (pluggable protocols) various component types including and not limited to Java, C++, BPEL, Spring and scripting an end to end service and data solution which includes support for Jaxb and SDO a lightweight runtime that works standalone or with other application servers a modular architecture that makes it easy to integrate with different technologies and to extend Integration with web20 technologies Apache Tuscany SCA is implemented in Java and C++ (referred to as Native)"

Setting up an infrastructure for Instant Messaging" article series. In my previous tutorials, I showed you how to setup the Openfire IM Server and how to configure the Spark client in order to connect to that server. In this tutorial, I will show you how to add XMPP messaging capabilities to your own application. I will use the Smack library, an Open Source XMPP (Jabber) client library for instant messaging and presence. Smack is a pure Java library and can be embedded into your applications to create anything from a full XMPP client to simple XMPP integrations.

The aim of this paper is a brief introduction to MDA technology and a summary / comparison to the approachments to MDA of AndroMDA and Acceleo, intending to be a practical and understandable summary Introduction Model-driven architecture (MDA) is a software design approach for the development of software systems. It provides a set of guidelines for the structuring of specifications, which are expressed as models. It was launched by the Object Management Group (OMG) in 2001 The Model-Driven Architecture approach defines system functionality using a platform-independent model (PIM) using an appropriate domain-specific language (DSL). One of the main aims of the MDA is to separate design from architecture. As the concepts and technologies used to realize designs and the concepts and technologies used to realize architectures have changed at their own pace, decoupling them allows system developers to choose from the best and most fitting in both domains. The design addresses the functional (use case) requirements while architecture provides the infrastructure through which non-functional requirements like scalability, reliability and performance are realized. MDA envisages that the platform independent model (PIM), which represents a conceptual design realizing the functional requirements, will survive changes in realization technologies and software architectures.

The Fornax-Platform is a development platform for tools related to the Model-Driven-Software-Development - MDSD. In this context tools are cartridges, transforms, ready-to-use generators or simple enhancements to make it easier to work in a MDSD environment. Another approach is to provide Howto's and tutorials that simplify the undestanding of MDSD. The Fornax-Platform provides infrastructure and tools to simplify the management and the development of such components and tools. It is independent from companies in this area of software development.

Xtext - Language Development Framework With Xtext you can easily create your own programming languages and domain-specific languages (DSLs). The framework supports the development of language infrastructures including compilers and interpreters as well as full blown Eclipse-based IDE integration. While Xtext equips you with a set of sensible defaults, you can tweak every single aspect of your language with Xtext's powerful APIs. A comprehensive documentation as well as the vivid community will help you getting started in no time. And if that is not enough you can buy trainings, consulting or support contracts delivered directly by the committers.

Eclipse provides a modeling infrastructure evolving around the Eclipse Modeling Framework (EMF) for which offering graphical representations and editing possibilities is essential. Graphiti is an Eclipse-based graphics framework that enables easy development of state-of-the-art diagram editors for domain models.

Couchbase: The End of the Trade-off Game Before Couchbase, ops teams managing web applications faced tough compromises when it came to databases. Screaming speed or durable, safe data storage. Super scale out virtually overnight or scaling up with lots of hardware upgrades. Bleeding-edge NoSQL or safe, but inflexible relational solutions. Couchbase eliminates those trade-offs. We supply extraordinary speed with complete safety and incorruptibility.  A growth path that will never force you to rethink your application infrastructure from datacenter deployments to mobile devices - one continuous, synchronized flow. Solutions that complement your other systems - including your RDBMS.  Technology that meets the needs of developers and conforms to the mission-critical demands of ops teams. This really is the beginning of a new era of NoSQL solutions. Couchbase: database solutions for a post-relational world. Learn more.

"Errai is a framework for building GWT applications Errai offers a set of components for building rich web applications using The Google Web Toolkit. The framework provides a unified federation and RPC infrastructure with true, uniform, asynchronous messaging across the client and server."

"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."
