Lulu.com is an on demand publisher with the benefits of very low start-up cost, better loyalty, distribution services etc. There are number of other Java/J2EE books published via Lulu.com. Go to
http://www.lulu.com and search for
Java J2EE to see other books. I am very happy with their set up and services. They do provide markeing services (I do my own google adwords) as well.
