Java Applets

Tekla Inc. developed a flower bouquet design Java applet for the commercial retail web site The Java applet allows the Internet customer to arrange and alter flower images into a bouquet from a shopping basket of selected flowers. A Microsoft Commerce Server program generates Active Server Pages that invoke the Java applet and access flower images in a database. The web customer can play with the simulated merchandise before purchasing.
