While Gartner Group research identified the Internet as the home of roughly half of Java deployments, the combined intranet (37 percent) and extranet (19 percent) proved to be the platform of choice for an entirely separate set of applications. A mere 4 percent of institutions deployed the same application on both the Internet and private networks.
Feiman said that most organizations began using Java in the form of applets over the Internet (see Figure 4), but applets have shifted in many cases to private networks, where companies can anticipate more uniform browser usage (different browsers may display applets incorrectly), and where high-bandwidth networks provide better support for large applets.
As Java develops, Feiman anticipates a shift to server-side Java (or servlets) as the preferred use for Java.
"Server-side developers have begun choosing Java applications and servlets for features that make it possible to program complex, changeable, and maintainable distributed business logic," concluded the report. "The shift from client-side to server-side Java represents the next, higher phase of Java adoption, and it will require [application development] organizations to master OO technology and distributed computing."
