This book is great. It helps with accelerated learning of key javabean concepts with just the right amount of code that will help to assist you in understanding key concepts, but not take forever to decipher. Ohh, did I mention the code WORKS. This is key and why a book company that I was a longtime supporter of let me down BIG TIME. This javabeans stuff has become fun. It's just a pitty that it had to be the 3rd java beans book I bought. Please don't make the same mistake and buy THIS BOOK FIRST and get to reading and coding. A good reference on the side won't hurt also: e.g., Java in a Nutshell.
