WebSphere Application Server V3.5 is the latest version of
the IBM open standards-based e-business application
deployment environment. This redbook will show you how to
install and use the product. It provides detailed insights
into the product's architecture and gives a wealth of
practical advice about how best to exploit the features of
WebSphere.
At the heart of the book are detailed step-by-step
descriptions of the tasks you will carry out to deploy and
execute your applications. These descriptions include not
only the use of the improved V3.5 GUI administration
console but also examples of how to exploit the new command
line administration facilities.
The redbook places these task descriptions in a broader
context by providing discussions of possible application
architectures, deployment topologies, best practices and
problem determination when using WebSphere Application
Server.
These discussions are founded on clear descriptions of
concepts and technologies that provide the framework for
WebSphere Application Server. These include the Servlet,
JSP and EJB APIs, security, transactions, JDBC, and
JNDI.
The redbook also contains details of the support for the
Servlet API V2.2 and JSP V1.1 APIs introduced by WebSphere
V3.5 Fix Pack 2 and examples of using these new
facilities.
