A Java MVC web framework focused in fast development.

Visage is a domain specific language (DSL) designed for the express purpose of writing user interfaces. A Visage application models the user interface you are designing both in appearance and function.

Easy to use, fast and stable. Create documents on-the-fly by placing objects like text, lines, bitmaps, etc. through function calls in any position. Can render the dimensions of text- and bitmap objects in advance, and allows to position other objects accordingly. Therefore allows absolute flexible dynamic layouts. You can add objects to any page at any time.

The goal of Usus is to provide Eclipse Plug-Ins that help to integrate common compiler and formatter settings in the Eclipse workspace, support Checkstyle, EclEmma and other tools, and apply some OO design metrics to analyse weak spots in the code.

Unitils is an open source library aimed at making unit testing easy and maintainable. Unitils builds further on existing libraries like dbunit and integrates with JUnit and TestNG. Unitils provides general asserion utilities, support for database testing, support for testing with mock objects and offers integration with Spring , Hibernate and the Java Persistence API (JPA). It has been designed to offer these services to unit tests in a very configurable and loosely coupled way. As a result, services can be added and extended very easily.

Umple is a programming language family. It adds abstractions such as Associations and Attributes derived from UML to object-oriented programming languages such as Java and PHP. Umple can also be used to create UML class diagrams textually.

UModel supports all 14 UML 2 diagram types and adds a unique diagram for modeling XML Schemas in UML. UModel also supports SysML for embedded system developers, and business process modeling (BPMN) for enterprise analysts. UModel includes code engineering functionality including code generation in Java, C#, and Visual Basic, reverse engineering of existing applications, and round-trip engineering. UModel was introduced in 2005, shortly after the ratification of the UML 2 standard, and is frequently updated to add new functionality, such as an integrated scripting environment and integration with Visual Studio 2010, and to support the newest versions of source code languages and the UML and XMI standards.

UMLStudio is a widely-used UML modeling tool. Its features include:
* Industry standard notations: UML, Booch, Structured, etc.
* Extensive support for UML 2.1 in UMLStudio 8.0.
* Support for Java, C++, C#, IDL, PHP, Ada 95, Forte
* Template-based, user-defined notation support
* Script-driven code/document generation and reverse engineering
* Fastest reverse engineering capability in the market
* User-defined symbol libraries and design patterns
* Support for popular image formats: bitmap, JPEG, PNG
* Capable of handling very large models (tens of thousands of classes)

The aim of uml@J is to introduce UML semantics into Java code. uml@J uses mainly:
* Java annotations to describe the UML elements;
* Aspect programming (AspectJ) to provide runtime behavior to annotated elements.

UML Lab is the first Modeling IDE to seamlessly combine modeling and programming with an intuitive class diagram editor and next-gen round-trip engineering (Round-Trip-Engineering NG). It recognizes Java legacy code and keeps your models clean and free from implementation details. This flexibility is achieved by using the same customizable Xpand Templates for forward and reverse engineering.
