Scalaffinity is a library providing core functionality for any social networking Web site based on ratings and recommendations. In other words, it is a generic collective intelligence library. Examples of such sites are Anobii, Rate Your Music, and Filmaffinity. It is designed to act as an out-of-the-box model for such Web applications. Nevertheless, Scalaffinity is fully customizable, extensible, and scalable. It incorporates lessons learned while reading "Collective Intelligence in Action" by Satnam Alag.
The Generic Repository (grepo) is a framework for Java which allows you to access (database) repositories in a generic and consistent manner. Using grepo, it is generally no longer required to provide all the boilerplate code which is necessary in order to access (database) repositories from Java. All you have to do is write appropriate database code (queries, procedures, functions, etc.), an appropriately annotated Java interface, and very little Spring configuration.
Metawidget is a "smart user interface widget" that populates itself, at runtime, with UI components to match the properties of your business objects. Metawidget does this without introducing new technologies. It inspects your existing back-end architecture (such as JavaBeans, existing annotations, existing XML configuration files) and creates widgets native to your existing front-end framework (such as Swing, Java Server Faces, Struts, Android). Metawidget does not replace or hide your existing UI framework and guarantees that your investment in its technology and knowledge is as valid as always.
Automated Business Logic (ABL) is a transaction logic engine. You define the behavior of your persistent objects declaratively, and the engine will take care of executing and enforcing your logic at commit time. Despite its simplicity, this approach is remarkably powerful, and can replace a large portion of the code in most transactional applications that use Hibernate.
LightAdmin speeds application development by bringing a pluggable, fully operational data management backend to JPA-based applications and relieving your codebase for more important things. It allows developers to define a data management backend with POJOs and JPA and customize it using simple Domain-specific language.
