Groovy is an agile, dynamic language for the JVM which combines many features from languages like Python, Ruby, and Smalltalk and makes them available to Java developers using a Java-like syntax. It is designed to help get things done on the Java platform in a quicker, more concise, and fun way. It can be used as an alternative compiler to javac to generate standard Java bytecode to be used by any Java project or it can be used dynamically as an alternative language, such as for scripting Java objects, templating, or writing unit test cases.
Combean is a Java framework for combinatorial structures like graphs or linear programs and optimization algorithms working with these structures. The objective of Combean is to integrate existing proven optimization packages as well as new implementations through a set of lean Java interfaces. Using a JavaBeans-based configuration mechanism, solvers for real-world optimization problems can be generated by plugging together the best-performing components. Using Combean as "glue" between optimization packages leads to more interoperable, adaptable, and flexible solutions.
[fleXive] is a Java EE 5 content repository aiming to support upcoming industry standards like CMIS. It strives to provide a holistic approach by offering a comprehensive set of tools and building blocks for building content-centric Web applications around a [fleXive] content repository. It speeds up development by easing many tedious and repetitive programming tasks and helping to keep your application(s) flexible during the development cycle and in production. It concentrates on enterprise-scale content modeling, storage, and retrieval, and includes comprehensive JSF support for displaying and manipulating these contents in (Web) applications. Key features include persistence, security, versioning, multi-language support, and scripting.
JCatapult is a development platform written in Java. Built for modularization, JCatapult allows developers to build modules such as a blog, content-management system, wiki, or any other reusable set of features and use them across multiple applications. Built on top of open source technologies, JCatapult is a robust and scalable platform. However, it is also agile and lightweight because it uses a convention over configuration approach.
[fleXive] CMS is a Java EE content management system based on JavaServer Faces 1.2. It combines the power of JSF XHTML templating with that of the Java EE 5 content repository, [fleXive]. Some highlights include dynamic JSF templating (Facelets), easy integration of custom logic with EJB or JSF beans, a modular structure, Maven support, generic data structures, and WebDAV and CMIS support. It incorporates all core [fleXive] features like security, versioning, multilinguism, and scripting.
Xtempore is a lightweight, modular, and powerful XML-based domain independent templating language. It's essentially a programming library which provides flexible tools for transforming an object (model) and an XML document (template) into another XML document. Xtempore is implemented in Java and requires JRE 1.5 or later and slf4j for logging.
