A J2EE application can be web-based or non-web-based. J2EE is a Java platform designed for the mainframe-scale computing typical of large enterprises. Sun Microsystems designed J2EE to simplify application development in a thin client tiered environment. J2EE simplifies application development and decreases the need for programming and programmer training by creating standardized, reusable modular components and by enabling the tier to handle many aspects of programming automatically.
