It looks like iRex has licensed tao's Intenet Java software (
http://tao-group.com/main.php?pageid...hp&temptype=t1) to run mobipocket.
It looks like it uses a program called "elate" to load a virtual image (target.img). Within that file, it calls "app/stdio/jcode" with the following options "-classpath MobipocketCoreReader.jar;kxml2-2.3.0.jar;irex.jar com.irex.mobipocket.reader.IrexReader" it also then requires the path of the mobipocket file.
I cannot use jcode to open a standard jar file, nor can I extract the image to locate other executables within it. I'll keep you posted with my progress.
