This book provides a practical, example-driven approach to understanding and implementing Enterprise JavaBeans (EJB). It aims to guide developers through the complexities of EJB technology by focusing on real-world application scenarios. The content is structured to build knowledge progressively, starting with fundamental concepts and moving towards more advanced topics, all illustrated with code examples.

The subject matter points to a technical text aimed at software developers seeking to learn or deepen their understanding of Enterprise JavaBeans. The 'by example' approach suggests a hands-on learning experience, likely focusing on practical application rather than theoretical deep dives. The publication date indicates it covers earlier versions of EJB technology, potentially making it a historical reference for those working with legacy systems or studying the evolution of Java EE.
