why don't you use the toolkit for this purpose !

Indeed, I would just use the toolkit itself. But if you want to do it by hand, you need to run preverify.exe on the .class files you want to use. You'll need two directories -- one directoy to hold the original .class files and one to hold the verified .class files. You then create your jar from the .class files in the latter. I'm surprised the book you're using doesn't show you how. Maybe the problem is you're using the toolkit -- it's not really meant for standalone/batch mode operation. You can download a MIDP reference implementation from the Sun site that is better suited for that. Complete instructions on this kind of stuff are given in my latest book, by the way.
