Taking a shotgun approach to commercial Java and related technologies, Java Electronic Commerce Sourcebook includes information on so many subjects that the table of contents is reminiscent of a popular pasta-sauce commercial. Selecting an Internet Service Provider (ISP)? It's in there. Want to advertise online? It's in there. Buying server hardware? In there. Writing HTML? It, too, is in there. Java Electronic Commerce Sourcebook does a good enough job of explaining commercial systems that use HTML and CGI, but the handful of chapters on Java are strikingly weak. The code listings for applets appear to have commercial potential, but the discussions of these are minimal. The code does appear on the companion CD-ROM, so if the Java programs do what you need, you're all set. Do not, however, expect to learn how to modify them in these pages. The code and introductory material will be of help to beginners, but programmers and anyone serious about using Java for commerce will want to look into better references.
