SlimWeb aims to replace Struts or JSF in your J2EE application, but is closer to Rails or TurboGears in its heavy use of convention-over-configuration, simplicity, and power. It aims to reduce (and most of the time completely eliminate) all boilerplate code, XML configuration files, and even deployment times.
Naked Objects is an application development platform. It's called Naked Objects because all you need to develop are your domain objects; the Naked Objects platform automatically creates an object-oriented user interface (giving you the choice of different styles) and the underlying storage mechanism (again, giving you the choice as how to persist your objects).

Sleutel is the Dutch word for key.
Subversion is a version control system. Originally designed to be a compelling replacement for CVS in the open source community, it has far exceeded that goal and seen widespread adoption in both open source and corporate environments. The Subversion project produces Subversion's core libraries (written in C), a fully functional command line client (svn), repository administration programs, API bindings for various languages (Perl, Python, Java, Ruby, etc.), and various additional tools and scripts.
XMLBeans is a technology for accessing XML by binding it to Java types. XMLBeans provides several ways to get at the XML. You can do this through XML schema that has been compiled to generate Java types that represent schema types. In this way, you can access instances of the schema through JavaBeans-style accessors after the fashion of "getFoo" and "setFoo". The XMLBeans API also allows you to reflect into the XML schema itself through an XML Schema Object model. There is a cursor model through which you can traverse the full XML infoset. There is support for XML DOM.
