One of the big advantages of JAVA is the ability to host applications directly on your website. This is called JAVA Webstart Technology. The user does not need to install individual applications on his/her local machine, and the web-launched applications are cross-platform compatible; otherwise, they run in Windows, Mac OS/X, Linux, and other UNIX variants. It is estimated that about 90% of computers have JAVA already installed, although some versions may be significantly out of date. This page demonstrates the power of Webstart and also gives you the opportunity to test-drive the Daily Calorie Needs Calculator v1.01.
