Overview
The future of business is e-commerce. Internet business-to-business (B2B) and business-to-consumer (B2C) initiatives have revolutionized the world's marketplaces. The companies that will survive in this new environment are those that can deliver quick solutions.
Enterprise Java ™ Programming with IBM® WebSphere® brings together six WebSphere experts, who share with you their vast knowledge of Java™ server technology and examine how Java and the Web have met the unfulfilled expectations of e-commerce customers. This hands-on guide delves into the most exciting parts of Java ™ 2 Enterprise Edition (J2EE™), servlets, JavaServer Pages™, and Enterprise JavaBeans™. These technologies are examined in the context of the IBM WebSphere Application Server and the IBM VisualAge® for Java, Enterprise Edition, development environment. This book provides techniques for maximizing your use of the Java technologies and IBM products to deliver effective and efficient e-commerce solutions.
Java and Web developers looking to produce new e-business applications will find Enterprise Javaª Programming with IBM® WebSphere® invaluable. Through the course of this book you will learn
- How to apply J2EE technologies (e.g., Java servlets, JavaServer Pages, and Enterprise JavaBeans) within the correct architectural frameworks
- How WebSphere Application Server, Advanced Edition, addresses the J2EE standard and what advantages it provides developers as a J2EE application server.
- What advantages VisualAge for Java, Enterprise Edition, conveys as a platform for developing J2EEprograms for deployment on the WebSphere Application Server, Advanced Edition.
Two CDs included: The first CD contains fully-functional evaluation copies of IBM DB2 7.1 Personal Developer's Edition, IBM WebSphere Application Server (Advanced Edition 3.5), and WebSphere Studio 3.5, as well as the example code from the book's case study. The second CD contains a copy of VisualAge for Java 3.5, Enterprise Entry Edition.
