An authoring system prepares a specified set of classes for preloading in
client devices lacking a virtual memory manager. The authoring system
converts the specified set of classes into a plurality of resource
modules, a subset of the resource modules each including items that have
pointers to items in other ones of the resource modules. The authoring
system generates a load module, for loading into the client devices, that
includes the plurality of resource modules, an interpreter and a startup
procedure. The interpreter is for executing, on the client devices,
programs in a predefined computer language. The specified set of classes
includes methods in the predefined computer language. The startup
procedure is for execution by the client devices when loading the
interpreter for execution. The startup procedure replaces pointers in the
resource modules with updated pointers in accordance with actual memory
locations of the resource modules in any particular one of the client
devices. The resource modules include a class table resource module, a
method table resource module, a field table resource module, a constant
pool resource module and a string resource module. The class data
structure includes pointers to items in the method table, field table and
constant pool resource modules, the field table resource module includes
pointers to items in the string resource module, and the constant pool
resource module includes pointers to items in the field table resource
module and items in the string resource module.
