This book is a thorough introduction to Java Message Service (JMS), the standard Java application program interface (API) from Sun Microsystems that supports the formal communication known as "messaging" between computers in a network. JMS provides a common interface to standard messaging protocols and to special messaging services in support of Java programs. The messages exchange crucial data between computers, rather than between users--information such as event notification and service requests. Messaging is often used to coordinate programs in dissimilar systems or written in different programming languages.Using the JMS interface, a programmer can invoke the messaging services of IBM's MQSeries, Progress Software's SonicMQ, and other popular messaging product vendors. In addition, JMS supports messages that contain serialized Java objects and messages that contain Extensible Markup Language (XML) pages.Messaging is a powerful new paradigm that makes it easier to uncouple different parts of an enterprise application. Messaging clients work by sending messages to a message server, which is responsible for delivering the messages to their destination. Message delivery is asynchronous, meaning that the client can continue working without waiting for the message to be delivered. The contents of the message can be anything from a simple text string to a serialized Java object or an XML document.Java Message Service shows how to build applications using the point-to-point and publish-and-subscribe models; how to use features like transactions and durable subscriptions to make an application reliable; and how to use messaging within Enterprise JavaBeans. It also introduces a new EJB type, the MessageDrivenBean, that is part of EJB 2.0, and discusses integration of messaging into J2EE.

For many Java developers, web services appeared to come out of nowhere. Its advantages are clear: web services are platform-independent (like Java itself), language-agnostic (a clear advantage over Java Rmi), can easily be tunneled through firewalls (an obvious benefit to anyone who has dealt with modern enterprise networks), object-oriented (we all know about that), and tends to be loosely coupled (allowing more flexible application development). But these advantages have been obscured by a cloud of hype and a proliferation of jargon that are difficult to penetrate. What are Soap, Uddi, Wsdl, and Jaxm? To say nothing of Jaxr, tModels, category bags, Wsfl, and other friends? And assuming that you understand what they are, how do you do anything with them? Do they live up to their promises? Are they really the future of network computing, or a dead end? Java Web Services gives the experienced Java developer a way into the Web Services world. It helps you to understand what's going on, what the technologies mean and how they relate, and shows Java developers how to put them to use to solve real problems. You'll learn what's real and what isn't; what the technologies are really supposed to do, and how they do it. Java Web Services shows you how to use Soap to perform remote method calls and message passing; how to use Wsdl to describe the interface to a web service or understand the interface of someone else's service; and how to use Uddi to advertise (publish) and look up services in each local or global registry. Java Web Services also discusses security issues, interoperability issues, integration with other Java enterprise technologies like Ejb; the work being done on the Jaxm and Jax-Rpc packages, and integration with Microsoft's .Net services. The web services picture is still taking shape; there are many platforms and Apis to consider, and many conflicting claims from different marketing groups. And although

Large It organizations increasingly face the challenge of integrating various web services, applications, and other technologies into a single network. The solution to finding a meaningful large-scale architecture that is capable of spanning a global enterprise appears to have been met in Esb, or Enterprise Service Bus. Rather than conform to the hub-and-spoke architecture of traditional enterprise application integration products, Esb provides a highly distributed approach to integration, with unique capabilities that allow individual departments or business units to build out their integration projects in incremental, digestible chunks, maintaining their own local control and autonomy, while still being able to connect together each integration project into a larger, more global integration fabric, or grid. Enterprise Service Bus offers a thorough introduction and overview for systems architects, system integrators, technical project leads, and Cto/Cio level managers who need to understand, assess, and evaluate this new approach. Written by Dave Chappell, one of the best known and authoritative voices in the field of enterprise middleware and standards-based integration, the book drills down into the technical details of the major components of Esb, showing how it can utilize an event-driven Soa to bring a variety of enterprise applications and services built on J2Ee, .Net, C/C++, and other legacy environments into the reach of the everyday It professional. With Enterprise Service Bus, readers become well versed in the problems faced by It organizations today, gaining an understanding of how current technology deficiencies impact business issues. Through the study of real-world use cases and integration patterns drawn from several industries using Esb-including Telcos, financial services, retail, B2B exchanges, energy, manufacturing, and more-the book clearly and coherently outlines the benefits of moving towar

The Enterprise Service Bus (ESB) is a technology that is being readily adopted within IT organizations across a variety of industries. An ESB provides a standards-based integration platform that combines messaging, web services, data transformation, and intelligent routing in an event-driven Service Oriented Architecture (SOA). ESBs are being used to solve real-world integration challenges in many unique ways, as we will explore throughout this book.Enterprise Service Bus contains practical strategies for understanding the architecture of an ESB while integrating diverse applications into enterprise-wide solutions. Throughout the book, there are integration patterns that show how an ESB can be applied toward solving today's application integration challenges. These strategies and patterns show how to integrate enterprise applications using standard components and interfaces.This book will provide you with a conceptual and architectural overview of the ESB from a seasoned expert in the areas of standards for enterprise messaging, web services, and SOA. Dave Chappell offers his unique insights gained from working with the pioneers and innovators of the ESB. This book will serve as a guide to define the ESB technology, as viewed through the eyes of an experienced integration architect who has worked with IT professionals on real-world ESB-based integration solutions.

In 1853, France annexed the Melanesian islands of New Caledonia to establish a convict colony and strategic port of call. Unlike other European settler–dominated countries in the Pacific, the territory’s indigenous people remained more numerous than immigrants for over a century. Despite military conquest, land dispossession, and epidemics, its thirty language groups survived on tribal reserves and nurtured customary traditions and identities. In addition, colonial segregation into the racial category of canaques helped them to find new unity. When neighboring anglophone colonies began to decolonize in the 1960s, France retained tight control of New Caledonia for its nickel reserves, reversing earlier policies that had granted greater autonomy for the islands. Anticolonial protest movements culminated in the 1980s Kanak revolt, after which two negotiated peace accords resulted in autonomy in a progressive form and officially recognized Kanak identity for the first time. But the near-parity of settlers and Kanak continues to make nation-building a challenging task, despite a 1998 agreement among Kanak and settlers to seek a “common destiny.”This study examines the rise in New Caledonia of rival identity formations that became increasingly polarized in the 1970s and examines in particular the emergence of activist discourses in favor of Kanak cultural nationalism and land reform, multiracial progressive sovereignty, or a combination of both aspirations. Most studies of modern New Caledonia focus on the violent 1980s uprising, which left deep scars on local memories and identities. Yet the genesis of that rebellion began with a handful of university students who painted graffiti on public buildings in 1969, and such activists discussed many of the same issues that face the country’s leadership today. After examining the historical, cultural, and intellectual background of that movement, this work draws on new research in public and private archives and interviews with participants to trace the rise of a nationalist movement that ultimately restored self-government and legalized indigenous aspirations for sovereignty in a local citizenship with its own symbols. Kanak now govern two out of three provinces and have an important voice in the Congress of New Caledonia, but they are a slight demographic minority. Their quest for nationhood must achieve consensus with the immigrant communities, much as the founders of the independence movement in the 1970s recommended.
