Java Rule Engine

Jess is a rule engine and scripting environment written entirely in Sun's Java language. Using Jess, you can build Java software that has the capacity to "reason" using knowledge you supply in the form of declarative rules. Jess is small, light, and one of the fastest rule engines available. Its powerful scripting language gives you access to all of Java's APIs. Jess includes a full-featured development environment based on the award-winning Eclipse platform.

Water tap with Internet Connection

Where does the Internet connected madness end? Televisions: okay. But refrigerators, toasters, ovens and dishwashers, connected by digital umbilical to the world wide web? The usefulness of merging Internet capabilities with everyday household appliances is more questionable; what next, the Internet connected faucet or toilet roll?

Transfer data faster with Bluetooth 3.0 + HS

Bluetooth SIG (Special Interest Group) gets official with the latest, greatest version of Bluetooth. Bluetooth 3.0 + HS, as it’ll be called, promises to be markedly faster than prior iterations thanks to the reliance on 802.11, which is the same protocol used by WiFi modules, routers, etc. The new standard obviously catapults Bluetooth into a new dimension; rather than being good for nothing more than sending images from one phone to another or syncing a fitness module to a DAP, v3.0 is nimble enough to handle camcorder-to-HDTV, PC-to-PMP and UMPC-to-printer transfers. In fact, the inclusion of the 802.11 Protocol Adaptation Layer (PAL) provides increased throughput of data transfers “at the approximate rate of 24Mbps.

Cewolf - Charting framework for web

Cewolf can be used inside a Servlet/JSP based web application to embed complex graphical charts of all kinds (e.g. line, pie, bar chart, plots, etc.) into a web page. Therefore it provides a full featured tag library to define all properties of the chart (colors, strokes, legend, etc.). Thus the JSP which embedds the chart is not polluted with any java code. Everything is described with XML conform tags.

Cewolf is based on JFreeChart and uses it's rendering engine to render the final chart image into the clients response stream. No files are created on server side. Everything is based on lightweight session objects and dynamic data analysis. Cewolf consists of one servlet which handles the chart rendering and a taglibrary which translates the chart definition included in the JSP into an HTML img tag which consults the rendering servlet for retrieval of the appropriate chart.

What is JavaOne

JavaOne is an annual conference (since 1996) put on by Sun Microsystems to discuss Java technologies, primarily among Java developers. JavaOne is held at the Moscone Center in San Francisco, California usually between April and June and typically runs from Sunday to Friday. Technical sessions on a variety of topics are held during the day. In the evening, Birds of a Feather (BOF) sessions are held at the Moscone Center and surrounding hotels. BOF sessions allow people to focus in on a particular aspect of Java technology.
Access to the technical sessions, keynote presentations, exhibits and BOF sessions requires a conference pass which usually costs between $1795 to $1995 USD.
