A complete guide to designing and using frameworks for Java applications. Java(TM) Application Frameworks. Application frameworks are a major leap forward in systems design and software reusability. Java has provided an enormous foundation upon which highly reusable components and applications can be built successfully. Building object-oriented systems is complex. Building highly reusable frameworks and components is even more challenging. This book substantially reduces the application frameworks' learning curve. Expert Darren Govoni follows a natural progression, from concept, to practice, to implementation. Building on examples of existing frameworks, he walks you through all the steps involved in designing frameworks, and provides guidelines on how to use frameworks within large architectures and systems. Important topics covered include: * Basic framework concepts and design techniques. * Using 8 design patterns-illustrated with UML-for framework design and implementation. * Constructing JavaBean components as the building blocks for a reusableframework . * A complete discussion of two powerful Java frameworks-Java Foundation Classes (JFC/Swing) and InfoBus-and how they adhere to the important traits found in good frameworks: proper use of abstraction through interfaces and abstract classes, substitution of application objects, extension or enhancement of key objects within the framework through abstract and default implementations. * How to manage complexity and reusability with abstracted foundations. * A complete methodology and architecture-Composite Foundation Architecture-for organizing and developing frameworks, components, and subsystems within a larger complex system. * Key considerations for developing frameworks within distributed architectures, including data access, GUIs, business objects, and distributed objects using JDBC, JFC, and RMI. * How to use enterprise frameworks such as Enterprise JavaBeans and CORBA (via Java IDL) to access, retrieve, and store information across a network. Visit the Companion Web site at www.wiley.com/compbooks/govoni/ for: * Source code from the application objects presented in this book. * Links to more information on frameworks.

Microservices and big-data increasingly confront us with the limitations of traditional input/output. In traditional IO, work that is IO-bound dominates threads. This wouldn't be such a big deal if we could add more threads cheaply, but threads are expensive on the JVM, and most other platforms. Even if threads were cheap and infinitely scalable, we'd still be confronted with the faulty nature of networks. Things break, and they often do so in subtle, but non-exceptional ways. Traditional approaches to integration bury the faulty nature of networks behind overly simplifying abstractions. We need something better.Join Spring Developer Advocate Josh Long for an introduction to reactive programming in the Spring ecosystem, leveraging the reactive streams specification, Reactor, Spring Boot, Spring Cloud and so much more.This book will cover important concepts in reactive programming including project Reactor and the reactive streams specification, data access, web programming, RPC with protocols like RSocket, testing, and integration and composition, and more.
