J2EE Unleashed presents techniques and examples for building
applications based on the Java 2 Enterprise Edition development model. The goal
of this book is not to teach the J2EE specification but to illustrate the best
practices for developing J2EE applications. It will cover the most commonly used
J2EE API's as well as migration techniques that can be used to port a J2EE
application from one platform to another.
The book will discuss all of these platforms with an emphasis on the
SilverStream application server, which is J2EE compliant and certified for
Windows and several UNIX platforms. Moreover, the book will illustrate how a
J2EE application can interface with most SQL based DBMS platforms including
ORACLE, INFORMIX, Microsoft SQL Server 7, SYBASE, IBM DB2 as well as others.
