JTOpen Lite / JTLite is a library of Java classes supporting the mobile programming models to a system running OS/400, i5/OS, or IBM i. The ‘Lite’ version of the java tool box for IBM i is intended to give our programming community a new smaller foot print toolkit for access IBM i native objects from Java running on mobile devices. The JTLite version is a newly written library of Java classes that is covering the basic needs for programmers and is written to maximize speed and footprint size.
