The DBacesslayer (or DBSlayer for short) is a lightweight database abstraction layer suitable for high-load Web sites where you need the scalable advantages of connection pooling. DBSlayer talks to clients via JSON over HTTP, meaning it's simple to monitor and can swiftly interoperate with any Web framework you choose.
Reverspring is a Java library that allows you to create Spring IoC XML files from POJO at runtime. CoI stands for Control of Inversion: Reverspring just inverts the inversion of control mechanism of Spring Framework, allowing you to (re)write Spring descriptors starting from your Java objects. With Reverspring, you can write process descriptors on XML files without reinventing a new DTD or XML schema, but just using the well known Spring IoC syntax.
The Spring Rich Client Project (RCP) is a sub-project of the Spring Framework. Spring-RCP's mission is to provide an elegant way to build highly-configurable, GUI-standards-following rich-client applications faster by leveraging the Spring Framework. It also provides a rich library of UI factories and support classes. Its initial focus is on providing support for Swing applications, but a goal of Spring-RCP is to be view agnostic as much as possible.
Location Source is an implementation of Java's Location API (JSR-179). It is intended to give Java applications access to location data on platforms that do not have a JSR-179 implementation of their own. It currently only runs on Windows Mobile using IBM's WebSphere Everyplace Micro Edition (WEME) 6.1.1 bu can easily be extended to run on other platforms. For example, you could use it on any laptop by tying it into SkyHook's Loci API.
