WebSphere V3.5 Handbook

Book Description

WebSphere Application Server V3.5 is the latest version of the IBM open standards-based e-business application deployment environment. This redbook provides detailed insights into the product’s architecture and a wealth of practical advice about how best to exploit WebSphere.

At the heart of the book are detailed step-by-step descriptions of the tasks you carry out to deploy and execute your applications.

The redbook places these task descriptions in a broader context by providing discussions of possible application architectures, deployment topologies, best practices and problem determination.

These discussions are underpinned by clear descriptions of concepts and technologies including the Servlet, JSP and EJB APIs, security, and transactions.

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.
