The next huge wave of Internet development, Java Aglets are lightweight mobile agents that enable the autonomous execution of programs on remote heterogeneous hosts. Because Java aglets automate many of the processes users must now perform manually, the technology is poised to transform the way many users interact with the Internet. Written by the creators of the technology, this book gives you the knowledge and skills you need to create Java aglets using IBM's Aglets Software Development Kit. Practical in focus, the book features numerous real-world examples of Java code that illustrate concepts and demonstrate Java aglets in action. Geared for Java programmers with no previous agent experience, the book presents a clear introduction to mobile agents that explains the basic conceptual model, agent behavior, the creation and disposal of agents, and agent transfer over a network. The appendix provides systematic, detailed coverage of the Java Aglet API describes and illustrates aglet anatomy, context, messaging, and collaboration.Moving beyond these basics, the book also presents advanced topics, such as design patterns for creating mobile agent applications, and provides a deeper look inside the Aglets framework to help you optimize the performance of your aglets.
Aglet security, a topic of critical importance for this mobile technology, is covered in depth. 0201325829B04062001
Dr. Danny B. Lange is director of Agent Frameworks at General Magic, Inc., located in Sunnyvale, California. Prior to joining General Magic, he was a visiting scientist at IBM's Toyko Research Laboratory, where he invented the Java Aglet and was the chief architect for IBM's Aglets Software Development Kit. Danny received an M.S. and Ph.D. in computer science from the Technical University of Denmark. Mitsuru Oshima, the lead implementor of the Aglets Software Development Kit and co-designer of the Aglets Framework, is a researcher at IBM's Tokyo Research Laboratory. 0201325829AB04062001
