This book is a guide to building a rich web application using Grails. The approach taken for building the application is incremental and iterative; each chapter will produce a working addition to the application, or iterate over existing features, as well as introduce and carefully explain the new part of the Grails framework used. The book does not go into exhaustive descriptions of every detail of Grails. While there is a lot of code in the book, there are very few large code listings. As you will find, it is not necessary to write reams of code to get results using Groovy and Grails. This book is aimed at Java web developers looking for ways to build web applications quickly, and wanting to find out how it's done quickly. If you are frustrated with integrating the many different frameworks that are available for web development and want to get on with building slick web applications for your users, then this book is for you. Grails is built on the Groovy language, but experience in Groovy is not required, as you will learn enough about Groovy to understand how to use Grails.

For a period of 6 years, the course retention rate for Marylhurst University's (MU) online courses was 91%, which is within four percentage points of its on-campus course retention rate (Schreck, 2001). This grounded theory, web-based, research study aims to explicate the reasons why MU online students complete courses at high rates and develop this understanding into an online student retention model. A grounded theory approach was used to conduct this study, which is described by Creswell (2002) as, "a systematic, qualitative procedure used to generate a theory that explains, at a broad conceptual level, a process, an action, or interaction about a substantive topic" (p. 439).

University websites hold considerable power for reaching prospective students via a cost-effective means as many view the Internet as the great equalizer among institutions. Unlike traditional forms of marketing, the quality of a website does not have to be limited by university size or budget as the price of accessing the medium and distributing the message can be equal for all. Therefore, in terms of marketing activities, websites have the potential to remove the disparity between what larger universities are able to accomplish and what smaller ones would like to achieve. But establishment of a website provides no guarantee that visitors, especially prospective students, will find what they seek within a reasonable time frame. Therein rests the dilemma for institutions - failure to locate desired information or difficulty negotiating the site might, and likely do, lead prospective students to exit. The focus of this research study was two-fold: to evaluate the extent to which university websites use relationship marketing techniques to communicate with prospective students and to evaluate the usability of these sites. This book is addressed to professionals in higher education responsible for student recruitment and marketing.

Since these technologies covered are different from each other, they are covered in separate chapters that are not interdependent; therefore you can learn to use whichever tool you want, without exploring the previous chapters. This approach sustains the learning per example paradigm and helps you to use the book as a quick guide for your favorite technologies. This book is recommended for Java developers who use at least one of the covered technologies (JSF, Struts, Hibernate, Seam, and so on). It is for all Java developers who are looking for a powerful, unitary tool, especially designed to increase the speed of development and quality of Java web applications. No matter how much (or how little) experience they have, developers of all levels will benefit as their use of JBoss Tools is directly proportional to the complexity of their application. Since JBoss Tools covers all levels of experience, you can use it at your own level for your own applications, without involving unnecessary features. All you need is to be familiar with the Eclipse environment and Java core, and to have some expertise in the technology for which you want to use the JBoss Tools. Basic expertise for each technology is provided in the book, but for more complete and detailed aspects you should read dedicated specifications, tutorials, and articles.

The simple and clear approach is ideal for beginners to Django.

As Web-based interactive 3D graphics, popularly referred to as Virtual Reality (VR), continue to become more affordable, research and development groups in various fields have been adopting Web-based VR technology. Despite substantial adoption, how and how much the technology benefits target users and the providers who choose to adapt the technology is not well understood. Previous research has established that VR provides users with unique human-computer interaction. However, little is known about how users experience the Web-based VR technology and how user-system interaction contributes to system usability. This book investigates user perception of Webbased VR comparing to conventional 2D graphics and system usability affected by the user-system interaction process. The impact of Web-based VR on system usability was empirically examined from an integrated view of technology acceptance in information systems and human-computer interaction. In addition, the impact of user characteristics on user-system interaction while using a VR system was examined. This book provides new knowledge about usability, sense of presence and technology acceptance in VR and provides insights for future research, which should be important to anyone designing, developing and evaluating a VR system in general and to an electronic commerce or market research system in particular.
