The most common use for client-server technology is to combine the graphical display capabilities of a desktop PC with the database and number-crunching power of a large central system. But peer-to-peer programs can run equally well.

Client/server applications are of increasing importance in industry; they are a significant first step towards a global distributed processing model. A very recent response to this trend is the Distributed Computing Environment (DCE) of the Open Software Foundation (OSF), the emerging new industry standard for distributed processing. The papers in this volume discuss the client/server approach based on DCE, illustrating and analyzing the functionality of important DCE components and applications. A number of contributions also focus on new models beyond traditional client/server processing and beyond DCE. The papers in this volume were presented at the International Workshop on the OSF Distributed Computing Environment, held in Karlsruhe, Germany, October 7-8, 1993. Following an introductory chapter, the contributions are grouped into parts on DCE analysis and comparison, application support, methods and tools, RPC extensions, and object-based systems.

Client/Server applications are of increasing importance in industry, and have been improved by advanced distributed object-oriented techniques, dedicated tool support and both multimedia and mobile computing extensions. Recent responses to this trend are standardized distributed platforms and models including the Distributed Computing Environment (DCE) of the Open Software Foundation (OS F), Open Distributed Processing (ODP), and the Common Object Request Broker Architecture (CORBA) of the Object Management Group (OMG). These proceedings are the compilation of papers from the technical stream of the IFIPIIEEE International Conference on Distributed Platforms, Dresden, Germany. This conference has been sponsored by IFIP TC6.1, by the IEEE Communications Society, and by the German Association of Computer Science (GI -Gesellschaft fur Informatik). ICDP'96 was organized jointly by Dresden University of Technology and Aachen University of Technology. It is closely related to the International Workshop on OSF DCE in Karlsruhe, 1993, and to the IFIP International Conference on Open Distributed Processing. ICDP has been designed to bring together researchers and practitioners who are studying and developing new methodologies, tools and technologies for advanced client/server environ ments, distributed systems, and network applications based on distributed platforms.

Both authors have taught the course of “Distributed Systems” for many years in the respective schools. During the teaching, we feel strongly that “Distributed systems” have evolved from traditional “LAN” based distributed systems towards “Internet based” systems. Although there exist many excellent textbooks on this topic, because of the fast development of distributed systems and network programming/protocols, we have difficulty in finding an appropriate textbook for the course of “distributed systems” with orientation to the requirement of the undergraduate level study for today’s distributed technology. Specifically, from - to-date concepts, algorithms, and models to implementations for both distributed system designs and application programming. Thus the philosophy behind this book is to integrate the concepts, algorithm designs and implementations of distributed systems based on network programming. After using several materials of other textbooks and research books, we found that many texts treat the distributed systems with separation of concepts, algorithm design and network programming and it is very difficult for students to map the concepts of distributed systems to the algorithm design, prototyping and implementations. This book intends to enable readers, especially postgraduates and senior undergraduate level, to study up-to-date concepts, algorithms and network programming skills for building modern distributed systems. It enables students not only to master the concepts of distributed network system but also to readily use the material introduced into implementation practices.

This updated edition features extensive revisions to explain OS/2 2.0 and its new functions. The authors also introduce new database features and incorporate them into RSQL. New SAA features, System View, and the Distributed Computing Environment (DCE) are fully described. Code developed with OS/2 2.0's Workframe environment and the new 32-bit C Set/2 compiler enables users to make improvements in tasking APIs and PM calls. Other new sections in the edition address Novell, TCP/IP, CPI-C, CUA'91 and the OS/2 Workplace Shell.

Now that Microsoft's systems have been unleashed onto the Internet, they are more vulnerable to attack. This book describes how Microsoft has taken Distributed Computer Environment/Remote Procedure Calls and implemented it over Server Message Block. The author presents Microsoft Developer NT system calls and shows what they look like over the wire.

This example-driven book offers a thorough introduction to Java's APIs for XML Web Services (JAX-WS) and RESTful Web Services (JAX-RS). Java Web Services: Up and Running takes a clear, pragmatic approach to these technologies by providing a mix of architectural overview, complete working code examples, and short yet precise instructions for compiling, deploying, and executing an application. You'll learn how to write web services from scratch and integrate existing services into your Java applications. With Java Web Services: Up and Running, you will: Understand the distinction between SOAP-based and REST-style services Write, deploy, and consume SOAP-based services in core Java Understand the Web Service Definition Language (WSDL) service contract Recognize the structure of a SOAP message Learn how to deliver Java-based RESTful web services and consume commercial RESTful services Know security requirements for SOAP- and REST-based web services Learn how to implement JAX-WS in various application servers Ideal for students as well as experienced programmers, Java Web Services: Up and Running is the concise guide you need to start working with these technologies right away.
