BEA Systems and Nokia have begun shipping technology that allows businesses to make e-commerce services available to people with cell phones or handheld computers. The two firms are bundling BEA's application server, software that runs e-commerce Web sites, with Nokia's wireless software called the WAP Server. The two pieces of software, used together, will allow businesses to make their applications available over the handheld devices. Bank customers, for example, can get stock quotes or perform financial transactions on the small devices.
