Webcockpit is a Web application generator for reporting and monitoring applications. It generates complete JSP-based Web applications which contain charts and tables whose contents are retrieved using database queries. The charts and tables can be configured to link to each other, enabling master detail-like drill-down. You can provide your own HTML or JSP template files which are mixed with the generated JSP to provide a final Web application.
SIOX4Java (Simple Interactive Object Extraction) is a Java SDK that provides a generic segmentation engine for extracting the foreground from still images with little user interaction. The underlying method (which has also been integrated into GIMP) is noise and motion blur robust and can easily be adapted for the segmentation of objects in videos. The SDK also contains an experimental feature called the "Detail Refinement Brush", which enables the removal of spill colors and manual refinement of highly detailed textures.
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.
