Abstract: A device (45) receives new program files (46) and uses pre-internalized images to avoid having to internalize a program file every time that program execution occurs. In one embodiment, a software Virtual Machine (50) in the device functions to implement the pre-internalization. Once the program files are pre-internalized to create images that are stored in a permanent memory (56) of the device, the images may subsequently be executed without having to perform a pre-internalization operation. Additionally, use of dynamic memory (52) is reduced in connection with subsequent program execution and execution time of new program files is reduced.

Abstract: An interface implements a file system for supporting Java record and resource management between an operating system using a first programming language other than Java and a suite of Java applications. The interface provides a method for maintaining any number of files to be open in a manner transparent to the Java applications. Location information of a file is put in storage allocated for usage by Java code when a maximum number of open files is exceeded. A table is used to translate between file names of differing length and to identify directories in a manner to provide a hierarchical file system. An identifier is associated with a shortened Java file name in the table to quickly identify an operating system file with a shortened file name.

Abstract: An interface (20) implements a file system for supporting Java record and resource management between an operating system (28) using a first programming language other than Java and a suite (22) of Java applications. The interface provides a method for maintaining any number of files to be open in a manner transparent to the Java applications. Location information of a file is put in storage allocated for usage by Java code when a maximum number of open files is exceeded. A table (506) is used to translate between file names of differing length and to identify directories in a manner to provide a hierarchical file system. An identifier is associated with a shortened Java file name in the table to quickly identify an operating system file with a shortened file name.
