Component Development For The Java Platform

Fra bagsiden: As a platform, Java defines the services needed to connect binary components at runtime safely and reliably. To truly take advantage of alle Java has to offer, you must consider not just development, but also deployment, and not just objects, but also components. The book delves into the component-oriented features of the Java platform, thoroughly discussing class loading, refelction, serialization, native interoperation and code generation.

Although industry has been leveraging the advancements of component-oriented development and assembly (CODA) technology for some time, there has long been a need for a book that provides a complete overview of the multiple technologies that support CODA. Filling this need, Component-Oriented Development and Assembly supplies comprehensive coverage of the principles, practice, and paradigm of component-oriented development and assembly. The first part of the book provides the conceptual foundation for component-oriented software. Part II focuses on the various standard Java component models and describes how to develop a component-oriented system using these component models. Part III covers the various aspects of the component-oriented development paradigm. Based on the authors’ research and teaching experience, the text focuses on the principles of component-oriented software development from a technical concepts perspective, designer’s perspective, programmer’s perspective, and manager’s perspective. Covering popular component development frameworks based on Java, it is suitable as a textbook for component-oriented software for undergraduate and postgraduate courses. It is also an ideal reference for anyone looking to adopt the component-oriented development paradigm. The book provides readers with access to all the source code used in the book on a companion site (http://www.codabook.com). The source code for the CODA implementation of the case study presented in Chapter 11 is also hosted on the website. The website will also serve as a technical forum for further discussions on the topic and for any updates to the book.

"Sams Teach Yourself Java in 21 Days" continues to be one of the most popular, best-selling Java tutorials on the market. Written by two expert technical writers, it has been acclaimed for its clear and personable writing, for its extensive use of examples, and for its logical and complete organization. This new edition of the book maintains and improves upon all these qualities, while updating, revising, and reorganizing the material to cover the latest developments in Java and to expand the book's coverage of core Java programming topics.Sun's new version of Java 2 Standard Edition--SDK version 1.4--is expected to be released by the end of 2001. According to Sun, version 1.4 builds upon Java's cross-platform support and security model with new features and functionality, enhanced performance and scalability, and improved reliability and serviceability.

The Java 2(tm) Platform, Enterprise Edition (J2EE) defines a new standard in enterprise solutions through a simplified, component-based development model. By extending the "write-once, run-anywhere(tm)" benefits of the Java programming language to enterprise servers, J2EE adds the scalability, robustness, and security required for today's vital e-commerce and enterprise solutions. The Java(tm) 2 Platform, Enterprise Edition: Platform and Components Specifications defines the architecture for developing applications with J2EE. This volume includes: Java(tm) 2 Platform, Enterprise Edition Specification, version 1.2 This specification defines the initial release of the J2EE platform. It discusses application architecture using Java(tm) Servlets, JavaServer Pages(tm), Enterprise JavaBeans(tm), and other technologies. It specifies application access to services such as JDBC(tm), Java Transaction API, JavaMail(tm), CORBA connectivity, and others. It also discusses J2EE policies regarding application deployment and security. Enterprise JavaBeans(tm) Specification, version 1.1 Enterprise JavaBeans technology provides the standard middle-tier components in the J2EE model. This technology provides simplified support for transaction management and remote object access, and it frees enterprise developers to focus on the business logic of their applications. Version 1.1 of the specification includes a number of enhancements, including mandatory entity beans and XML deployment descriptors. Java(tm) Servlet Specification, version 2.2 Java Servlets technology defines a standard for developing server-side behaviors in web applications based on the Java programming language. As part of the J2EE specifications, servlets technology supports development of dynamic web content for e-commerce and other enterprise applications. JavaServer Pages(tm) Specification, version 1.2 The JavaServer Pages (JSP) technology simplifies the development and deployment of interactive web applications. Using an extensible markup language based on HTML and the Java programming language, JSP defines a server-side mechanism to allow content experts greater freedom in creating and displaying dynamic web content. Developed with the input of a wide range of industry experts, these specifications define a new standard for resolving many complex issues related to developing, deploying, and managing multi-tier enterprise applications. 0201704560B04062001

This book simplifies the creation of well-designed enterprise applications using the upgraded Enterprise JavaBeans 2.0 specification. Experienced Java platform mentors Gail Anderson and Paul Anderson use detailed code examples to introduce every key skill involved in creating components, stand-alone Java platform clients, and JavaServer pages. They introduce powerful EJB platform design patterns and show how to apply them in real-world projects while avoiding critical errors in application design. Each chapter includes a "Design Guidelines and Patterns" section designed to help readers assess tradeoffs associated with design decisions, and key point summaries that tie together important concepts. In short, Anderson and Anderson give readers everything they need to build EJB 2.0 platform applications with maximum robustness, scalability, and performance.

Industrial development of software systems needs to be guided by recognized engineering principles. Commercial-off-the-shelf (COTS) components enable the systematic and cost-effective reuse of prefabricated tested parts, a characteristic approach of mature engineering disciplines. This reuse necessitates a thorough test of these components to make sure that each works as specified in a real context. Beydeda and Gruhn invited leading researchers in the area of component testing to contribute to this monograph, which covers all related aspects from testing components in a context-independent manner through testing components in the context of a specific system to testing complete systems built from different components. The authors take the viewpoints of both component developers and component users, and their contributions encompass functional requirements such as correctness and functionality compliance as well as non-functional requirements like performance and robustness. Overall this monograph offers researchers, graduate students and advanced professionals a unique and comprehensive overview of the state of the art in testing COTS components and COTS-based systems.

Drawing on the authors knowledge of the Java programming language and their extensive experience working on performance issues, the book reveals common mistakes and misconceptions concerning the performance characteristics of Java technologies. It offers overall development strategies and concrete, battle-tested techniques to dramatically improve the performance of applications constructed with the Java programming language. Java Platform Performance highlights the importance of integrating performance evaluation into the application development process and discusses measurement techniques. The book then presents practical tactics for enhancing application performance in the areas of I/O, RAM footprint, small object management, algorithms, data structures, Swing, and deployment. Specific topics covered include: *Incorporating performance evaluation into the development process *Profiling and benchmarking *Building scalable, fast Swing GUIs *Using high-speed I/O *Computing and controlling the RAM footprint *Reducing the number of classes *Eliminating temporary objects *Selecting high-performance algorithms and data structures *Using Java native code and applet packaging efficiently
