New: SVGObjects -- "SVGObjects is a framework for vending SVG components from WebObjects. Now a technology pre-release, SVGObjects Framework demonstrates the use of Apple's WebObjects to serve dynamic SVG content."

Another tool for WO, ReportMill, makes it very easy to dynamically generate complex PDF and Flash content from WebObjects.

The great part about WebObjects is reusability. SVGObjects and Reportmill use the same Enterprise Objects classes you wrote for your Web app to generate SVG, PDF and Flash.
