Abstract

A system for creating a custom environment for executing application programs in a target device. The system broadens the applicability of software environments like Java by providing custom pre-loaded classes for application programs and by customizing the procedures for class loading to the available resources in the target device. The system includes tools for generating a pre-load class list that specifies a set of classes needed to support the application program. The tools build the custom environment including a set of code for a virtual machine and a set of code for each of a set of pre-loaded classes specified in the pre-load class list. The virtual machine loads classes from the pre-loaded classes, a file system class library, and/or a networked class library using widely available network protocols.
