  • All the code examples in this book are coded as Java applets so that they can be used with Java-enabled Web browsers and published on the Web. At the time of this writing, the current release of Java is release 1.1.5 with version 1.2 just appearing as a developer release. Java versions 1.1 and later add many new features, such as a completely new event model, but many Web browsers have yet to fully incorporate these new features. Therefore, the applets in this book are coded to be compatible with the earlier Java 1.0.2 standard so that they work with the widest variety of web browser....

  • Asmentioned in the introduction, the information associatedwith an event is represented by a data structure called a notification.We refer to the datamodel or encoding schema of notifications as the event notification model or simply event model. Most existing event notification services adopt a simple record- like structure for notifications, while some more recent frameworks define an object-oriented model (e.g., the Java™ Distributed Event Specification [Sun Microsystems 1998] and the CORBA Notification Service [Object Management Group 1998b]).

  • This book is for every Java web developer, regardless of his or her level of expertise. It is designed primarily for intermediate to advanced developers, who understand the specifics of the various web APIs in Java but haven’t yet mastered the best way to apply them. It is perfect for developers who have heard terms like Model- View-Controller and Model 2, but weren’t present for the series of events that led to the widespread adoption of these best practices.

  • Messaging systems based on queuing include products such as Microsoft’s MSMQ [28]and IBM’s MQSeries [29]. The queuing model with their store-and-forward mechanisms come into play where the sender of the message expects someone to handle the message while imposing asynchronous communication and guaranteed delivery constraints. A widely used standard in messaging is the Message Passing Interface Standard (MPI) [21]. MPI is designed for high performance on both massively parallel machines and workstation clusters.
