"EMF URI handler implementation that can persist EMF object instances to MongoDB. "

"Morphia is a lightweight type-safe library for mapping Java objects to/from MongoDB: Easy to use, and very lightweight; reflection is used once per type and cached for good performance. Datastore and DAO access abstractions, or roll your own... Type-safe, and Fluent Query support with (runtime) validation Annotations based mapping behavior; there are no XML files. Extensions: Validation (jsr303), and SLF4J Logging"

"Blueprint provides a dependency injection framework for OSGi and was standardized by the OSGi Alliance in OSGi Compendium R4.2. It is designed to deal with the dynamic nature of OSGi, where services can become available and unavailable at any time. The specification is also designed to work with plain old Java objects (POJOs) enabling simple components to be written and unit tested in a JSE environment without needing to be aware of how they are assembled. The Blueprint XML files that define and describe the assembly of various components are key to the Blueprint programming model. The specification describes how the components get instantiated and wired together to form a running module. The following documentation covers the 80:20 usage of Blueprint. For further details, please refer to the OSGi Compendium R4.2 specification."

"The Qt SOAP project provides basic web service support with version 1.1 of the SOAP protocol. The SOAP (Simple Object Access Protocol) component recognizes the XML standard for describing how to exchange messages. Its primary usage is to invoke web services and get responses from Qt-based applications. These classes make it easy to construct, send, receive and process SOAP messages on the client side."

"An "executable" UML model is one with a behavioral specification detailed enough that it can effectively be "run" as a program. This can be extremely valuable in order to test and validate the model, independently of the one or more implementation platforms to which the system being modeled will ultimately be deployed. Or, in some cases, the model itself can actually be run as the production implementation, given an appropriate execution environment. There have been model execution tools and environments for years, even before UML. However, each tool defined its own semantics for model execution, often including a proprietary action language, and models developed in one tool could not be interchanged with or interoperate with models developed in another tool. A previous post described Stephen Mellor's quest of more than a decade to change this through OMG standards for precise UML model execution semantics and a UML action language. In 2008, this led to the adoption of the Foundational UML (fUML) specification, providing the first precise operational and base semantics for a subset of UML encompassing most object-oriented and activity modeling. The fUML specification still did not provide any new concrete surface syntax, however, tying the precise semantics solely to the existing abstract syntax model of UML. This meant that, in order to fully specify a detailed behavior in a UML model - say the effect behavior of a transition on a state machine or the method of an operation of a class - one still had to draw a very detailed, graphical activity diagram.

" Openbravo ERP REST consists of a framework offering security and exception services and a data access REST web service implementation. The data access (DAL) REST web services provide a CRUD-like web service so that external applications can retrieve, update, create and delete business objects through standard HTTP requests. "

The Java Content Repository (JCR) standard, which is based on the Java Specification Requests JSR170 (version 1.0) and JSR 283 (version 2.0), provides a Java-centric object-oriented storage API specifically targeted at content management scenarios. The JCR is not a content management system or a full-fledged content management system API, but rather a content repository API. A content repository provides a common API for all content-driven applications and CMS components, which require access to the content. It provides methods to read, write, and query content. The primary motivation of the JCR standard is to provide a standard and vendor-neutral programmatic interface for content repositories, allowing applications of multiple vendors to interact efficiently.

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

" Should you need to compile an OT/J program outside the OTDT, the following steps should enable you to use ANT for this task: download ecotj.jar you'll always find the latest version here in the column "Command Line Compiler" add it to your ANT runtime classpath (either place it in your ant_lib directory or provide the path by a -lib command line option to ant). in your build.xml set the property build.compiler to use the OTDT compiler in tasks, like that: "

" OT/J: extreme modularity Whenever modularity gets tricky, OT/J provides just one more dimension for your architecture. With OT/J there's no excuse for any architectural workarounds. OT/J: extreme reuse With OT/J any existing piece of Java code is reusable. Existing components can be adapted to specific needs in full adherence to your projects requirements and without compromising a crisp modular architecture. The fabric for quality software OT/J is the fabric from which high quality software can be produced: flexible, durable, elegant. OT/J in the Wiki"
