Spiders, bots, and aggregators are all so-called intelligent agents, which execute tasks on the Web without the intervention of a human being. Spiders go out on the Web and identify multiple sites with information on a chosen topic and retrieve the information. Bots find information within one site by cataloging and retrieving it. Aggregrators gather data from multiple sites and consolidate it on one page, such as credit card, bank account, and investment account data. This book offer offers a complete toolkit for the Java programmer who wants to build bots, spiders, and aggregrators. It teaches the basic low-level HTTP/network programming Java programmers need to get going and then dives into how to create useful intelligent agent applications. It is aimed not just at Java programmers but JSP programmers as well. The CD-ROM includes all the source code for the author's intelligent agent platform, which readers can use to build their own spiders, bots, and aggregators.
