Audience
Readers should have a good working knowledge of the Java language
itself. We don't expect that readers will be
entirely fluent with J2EE, but we do expect a top-level knowledge of
what's available in the J2EE technology stack (we
include a brief overview in Chapter 1 for those
who've been away, summarizing the problems that each
technology solves). In the presentation tier section, readers will
need some basic knowledge of Java Servlets and of HTTP and web
protocols in general, but we explain some of the nuances as we
encounter them. Since enterprise applications tend to be
database-intensive, the business tier section
(Chapters 6-10) makes
frequent use of databases.
For a fast-paced primer on all the J2EE technologies, check out
Java Enterprise in a Nutshell by William
Crawford, Jim Farley, and David Flanagan, also from
O'Reilly & Associates.
