Hmm, that book explains in detail how Java security works and how it is implemented, but I've found it lacking when it comes to explaining how to apply those security features.
I think this book provides an easier start for someone looking to apply security principles in Java code.
Oh, and not to step on the original posters toes, but just to point out the obvious: Here at JavaRanch we take a strong position against the illicit use of copyrighted material (such as illegal electronic copies of books), so nobody had better post links to ripped off material on a file sharing site.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
