This book constitutes the refereed proceedings of the Second International Conference on Electronic Commerce and Web Technologies， EC-Web 2001， held in Munich， Germany in September 2001. The 31 revised full papers presented together with one invited survey were carefully reviewed and selected from more than 80 submissions. The papers are organized in topical sections on Web software development; XML transformation; electronic payment， simulation and case studies; modeling design， and complex transactions; security aspects; electronic negotiation and trust; product catalogs; Web site engineering; user behaviour and modeling; and business models and system aspects.

One of the most important reasons for the current intensity of interest in agent technology is that the concept of an agent， as an autonomous system capable of interacting with other agents in order to satisfy its design objectives， is a natural one for software designers. Just as we can understand many systems as being composed of essentially passive objects， which have a state and upon which we can perform operations， so we can understand many others as being made up of interacting semi-autonomous agents. This book brings together revised versions of papers presented at the First International Workshop on Agent-Oriented Software Engineering， AOSE 2000， held in Limerick， Ireland， in conjunction with ICSE 2000， and several invited papers. As a comprehensive and competent overview of agent-oriented software engineering， the book addresses software engineers interested in the new paradigm and technology as well as research and development professionals active in agent technology.

The agent metaphor and the agent-based approach to systems design constitute a promising new paradigm for building complex distributed systems. However， until now， the majority of the agent-based applications available have been built by researchers who specialize in agent-based computing and distributed artificial intelligence. If agent-based computing is to become anything more than a niche technology practiced by the few， then the base of people who can successfully apply the approach needs to be broadened dramatically. A major step in this broadening endeavor is the development of methodologies for agent-oriented software engineering accessible to and attractive for professional software engineers in their daily work. Against this background， this book presents one of the first co-herent attempts to develop such a methodology for a broad class of agent-based systems. The author provides a clear introduction to the key issues in the field of agent-oriented software engineering as well as a comprehensive overview of the state of the art. The core contribution is the presentation and application-based evalua-tion of the MASSIVE methodology for iterative multiagent system engineering. The bookwill serve as a valuable source of reference for R&D pro-fessionals active in agent-based computing as well as a gentle and systems development and anced students.

Modern software systems are becoming more complex in many ways and have to cope with a growing number of abnormal situations which， in turn， are increasingly complex to handle. The most general way of dealing with these problems is by incorporating exception handling techniques in software design. In the past， various exception handling models and techniques have been proposed and many of them are part of practical languages and software composition technologies.This book is composed of five parts， which deal with topics related to exception handling in the context of programming language models， design methodologies， concurrent and distributed systems， applications and experiences， and large-scale systems such as database and workflow process mangagement systems. The 17 coherently written chapters by leading researchers competently address a wide range of issues in exception handling.

This book constitutes the refereed proceedings of the Third International Conference on Product Focused Software Process Improvement， PROFES 2001， held in Kaiserslautern， Germany， in September 2001.The 27 revised full papers presented were carefully reviewed and selected from numerous submissions.
