VRaptor 2 is a Web-based MVC and IOC framework based on many frameworks and ideas (Seam, Stripes, Webwork, Hibernate Annotations, etc). It makes full use of Java 5 Annotations. It favors convention over configuration, because configuration in XML/properties/annotations is always easy to make mistakes and repetitive (aka copy and paste in many places). This framework uses a more imperative approach, instead of having many XML files to configure lifecycle and other properties. Most of the settings go inside plain Java objects (POJO), so the team knows exactly what is going on and where.

It is made of pure Java code and does not require any native library.
Jim (Java Image Manager) is a program for managing your personal images (photos, etc.). While Jim is really easy to use, its tagging technology is quite powerful. A plugin system makes it easy extensible with new technologies. It runs on several operating systems (including Windows, Linux and many more); all you need is a Java Runtime Environment.

A database and LDAP can be used to store user data. "MODE Z" is supported for faster transfers.
Kabeja is a Java library for parsing CAD data (i.e. Autodesk's DXF format) and converting to SVG (dxf2svg). You can use Kabeja from the command line or embed it into your application. It includes a plain DXF2SVGViewer and integration into the Cocoon XML Web development framework and the Inkscape SVG editor.
