J Consortium submits Java file format to ISO for approval

Paris, France; Cupertino, Calif.— For small computing devices, such as smart phones and personal digital assistants (PDAs), that have limited memory for computing, J Consortium is submitting to the ISO/IEC JTC 1 standards organization an efficient file format for Java applications called JEFF. This format specification reduces requirements for runtime memory, and has already helped enable broad deployment of Java technology to small devices. “I’m proud to submit our JEFF specification for Publicly Available Specifications approval by the ISO/IEC JTC1, a well-recognized formal international standardization body,” says Wendy Fong, J Consortium’s chairman. “And I am pleased that several companies will be offering JEFF products and realizing the dream that an open, vendor-neutral Java specification will allow multiple independent implementations.” J Consortium released the JEFF specification in March 2001. It allows developers to store non-pre-linked Java classes in a form that does not require any modification or decompression for efficient execution. This reduces runtime memory and processing start time, and yet preserves the flexibility of allowing programs to be easily updated. Individual classes may be replaced instead of complete programs.
