Features: With the continuous development of Internet applications and the emergence of next-generation distributed computing models like Web services, J2EE technology is becoming a universal platform technology for developing Internet-based and transactional applications. Developers can build flexible and reusable components and applications on this platform, making it a trendsetter in enterprise applications over the past few years, thereby making the development of enterprise application systems faster and more convenient. J2EE itself is a standard that provides a benchmark for different vendors to create platform products, enabling interoperability between various J2EE platform products. When developing applications using J2EE, it is essential to carefully consider the services provided by the platform and how application components can best leverage these services. This book offers numerous practical tips for efficiently constructing J2EE components and integrating them into applications, including how to evaluate and select the correct software component collections and services. It provides practical techniques for J2EE software development methods and using reference architectures to build applications. Starting from the concept of business applications, it defines and explains the concepts and related content of three key components of the reference architecture: Business Object Architecture, Service-Oriented Architecture, and User Interaction Architecture. It analyzes the relevance and implementation methods of each part from both principles and technical perspectives, followed by the implementation and practical applications of the corresponding application architecture. A banking application example is used throughout the book to vividly illustrate the practical application of J2EE. After discussing the architecture and many practical techniques, the later part of the book delves deeper into the issues of application security, performance, and reusability. This book provides concepts and examples on how to quickly and high-qualityly build applications, which will be helpful for every Java technical professional using J2EE to develop business applications. It is suitable for computer science undergraduates, graduate students, as well as software engineers and network engineers engaged in software and e-commerce development for learning and reference. J2EE technology is becoming a widely used platform technology for developing Internet-based and transactional business applications. During the implementation of J2EE projects, robust application design patterns must be applied. This book proposes an application structure called a reference architecture from the developer's perspective, primarily consisting of three components: Business Object Architecture, Service-Oriented Architecture, and User Interaction Architecture. This design pattern can adapt to dynamically changing business and user needs. The book details how to leverage component technology to implement this application structure, as well as how to efficiently develop J2EE components and integrate them into applications, showcasing a series of practical techniques for J2EE application development, including evaluating and selecting appropriate software components and services. From a principle and technical perspective, the book analyzes the causes of system performance issues and their solutions. Using the banking application throughout the book, readers will gain a deeper understanding of all concepts and practical techniques. Additionally, the book discusses how to integrate third-party technologies such as Jakarta Struts into applications, as well as issues related to security, performance engineering, and reusability. This book can serve as a reference for J2EE developers and also provide valuable assistance for J2EE project managers and readers studying J2EE-related content.
