"If you're going to run enterprise Java applications in an n-tier architecture, you're going to need an applications server." -Java Pro Magazine, Fall 2001.</P>

An application server is a crucial component of any serious J2EE application. BEA's WebLogic Server (WLS) is the leading product (34% per BEA), incorporating standard models for component programming with features that tie in with J2EE "parts" including EJB 2.0 and JSP. Version 7.0 (due Summer 2002) makes WLS one of the first application servers to achieve full compliance with J2EE version 1.3, which should only increase its share of the enterprise Java application market.</P>

Sams Teach Yourself BEA WebLogic Server 7.0 in 21 Days covers all the features of WLS and how they enhance J2EE architecture. The book then covers WebLogic's role in devloping Web pages with Servlets and JavaServer Pages, components with Enterprise JavaBeans, database-driven applications with JDBC, and more. Later chapters include advanced J2EE concepts including messaging, transaction management and debugging. Each lesson is illustrated with real-world examples and finishes with useful questions and exercises to test readers' learning.</P>
