"The aspiring Grid programmer need be frustrated no longer. Borja Sotomayor and Lisa Childers have produced, in ’Globus Toolkit 4: Programming Java Services’, a masterly tutorial text that is surely destined to find a place beside every Grid programmers keyboard."
- from the Foreword, by Ian Foster and Carl Kesselman, authors of The Grid 2

The Globus Toolkit (http://www.globus.org/toolkit/) is a key technology in Grid Computing, the exciting new computing paradigm that allows users to share processing power, data, storage, and other computing resources across institutional and geographic boundaries. Globus Toolkit 4: Programming Java Services provides an introduction to the latest version of this widely acclaimed toolkit. Based on the popular web-based The Globus Toolkit 4 Programmer’s Tutorial, this book far surpasses that document, providing greater detail, quick reference appendices, and many additional examples. If youre making the leap into Grid Computing using the Globus Toolkit, youll want Globus Toolkit 4: Programming Java Services at your side as you take your first steps.

Features:
+ Written for newcomers to Globus Toolkit, but filled with useful information for experienced users.
+ Clearly situates Globus application development within the context of Web Services and evolving Grid standards.
+ Provides detailed coverage of Web Services programming with the Globus Toolkit’s Java WS Core component.
+ Covers basic aspects of developing secure services using the Grid Security Infrastructure (GSI).
+ Uses simple, didactic examples throughout the book, but also includes a more elaborate example, the FileBuy application, that showcases common design patterns found in Globus applications.
+ Concludes with useful reference appendices.

hides some of the complexity of Globus
Will Globus ever be successful? It is very specialised, and currently it seems only a few universities and companies use it. To encourage greater uptake, this book shows how to write various Java services in Globus. An acknowledgment of Java’s popularity, in part driven by the relative ease of programming in it.

This toolkit does hide some of the programming complexity of Globus. A Java programmer will still need to learn somethings specific to Globus. There appears to be no way around this with the current version of Globus.

Another attraction of the book is due to the big interest about Web Services. While these are independent of any language in which to encode them, in practice, a lot of work has been done in Java.
