Enterprise Java Beans (EJB) is a server-side component architecture and a central part of the J2EE platform. EJB enables the rapid development of distributed, secure and portable Java applications. This follow-up title to Professional Java Server Programming - J2EE Edition goes from design principles and theory right through to building robust real-world applications and concludes with several case studies including EJB applications and COM integration. Published to coincide with the EJB 2.0 specification this book is an in-depth guide to every aspect of this component architecture.

Jini is a simple set of Java Classes and services that allows devices (e.g., printers) and services (e.g., printing) to access each other seamlessly, adapt to a continually changing environment, and share code and configurations transparently. Jini has the potential to radically alter our use of computer networks, since it allows and encourages totally new types of services and new uses of existing networks."Jini in a Nutshell" is a quick reference guide to developing services and clients using Jini. It covers everything an experienced Java programmer needs to know to implement Jini, including tutorial chapters to get you up to speed quickly and reference chapters that analyze and explain every Java package related to Jini. Over the course of the book the authors develop a complete example program--with samples of both server and client applications.Topics covered include: Setting up the Jini programming environmentRMIBasic and advanced Jini programmingJini services, including JavaSpacesJini utilitiesSecurity"Jini in a Nutshell" covers the Jini 1.0 specification and requires the Java 2 Platform.

Annotation "JavaSpaces technology is a powerful Jini service from Sun Microsystems, Inc. that facilitates building distributed applications. The JavaSpaces model provides persistent object exchange "areas" in which remote Java processes can coordinate their actions and exchange data. JavaSpaces technology supplies a necessary, cross-platform framework for distributed computing with Jini technology." "This book introduces the JavaSpaces technology architecture and provides a comprehensive description of the model. Using an example-driven approach, this book shows you how to use JavaSpaces technology to develop distributed computing applications." "JavaSpaces Principles, Patterns, and Practice also includes two full-scale applications - one collaborative and the other parallel - that demonstrate how to put the JavaSpaces model to work."--BOOK JACKET.

Jini and JavaSpaces Application Development demonstrates real-world usage and application of the Jini technology. Specifically the book presents and builds on the concept of a "virtual development center." It will use the concepts of distributed development, open-source, virtual corporations, and the borderless world as a backdrop to developing products and services using Jini and JavaSpaces technologies.

"Java P2P Unleashed" provides a single source for Java developers who want to develop P2P systems. The book explains the benefits of each technology and shows how to fit the P2P "pieces" together - both in building new systems and integrating with existing ones. starts with a discussion of the P2P architecture, referencing similarities with existing, familiar systems while previewing several types of P2P applications. It explains how to plan ahead for security, routing, performance and other issues when developing a P2P application. Each technology included in the book - JXTA, Jini, JavaSpaces, J2EE, Web services - is approached from a P2P perspective, focusing on implementation concerns Java developers will face while using them. The last section includes several large-scale examples of different P2P applications - managing content, building communities, integrating services, routing messages, and using intelligent agents to gather information. The final chapter looks ahead to future developments in Java P2P technologies.

missions in fact also treat an envisaged mutual impact among them. As for the 2002 edition in Irvine, the organizers wanted to stimulate this cross-pollination with a program of shared famous keynote speakers (this year we got Sycara, - ble, Soley and Mylopoulos!), and encouraged multiple attendance by providing authors with free access to another conference or workshop of their choice. We received an even larger number of submissions than last year for the three conferences (360 in total) and the workshops (170 in total). Not only can we therefore again claim a measurable success in attracting a representative volume of scienti?c papers, but such a harvest allowed the program committees of course to compose a high-quality cross-section of worldwide research in the areas covered. In spite of the increased number of submissions, the Program Chairs of the three main conferences decided to accept only approximately the same number of papers for presentation and publication as in 2002 (i. e. , around 1 paper out of every 4–5 submitted). For the workshops, the acceptance rate was about 1 in 2. Also for this reason, we decided to separate the proceedings into two volumes with their own titles, and we are grateful to Springer-Verlag for their collaboration in producing these two books. The reviewing process by the respective program committees was very professional and each paper in the main conferences was reviewed by at least three referees.
