--(BUSINESS WIRE)

    Who:    Chuck Cavaness, Senior Technologist at S1 Corporation
            (Nasdaq: SONE), the leading global provider of Enterprise
            software solutions

    What:   Programming Jakarta Struts, published by
            O'Reilly & Associates, Inc.

    When:   The book, which provides insight and guidance for
            developers using Struts to create Web-based applications,
            will hit bookshelves this fall to coincide with the
            general availability of Jakarta Struts 1.1.

Since early 2000, developers across multiple industries including banking, automotive, e-commerce and healthcare have utilized Jakarta Struts as a framework for enabling the efficient creation of Web-based applications. As Struts continued to gain wide popularity and acceptance, Chuck Cavaness recognized the need for an educational guide that would help readers leverage Struts 1.1, a significantly enhanced framework from the flagship version. Struts 1.1 promises to better enable developers to focus on solving business problems, rather than spending precious time creating application infrastructure. Programming Jakarta Struts highlights the new features delivered in version 1.1, such as better exception handling, built-in client- and server-side validation support, and richer JSP custom tag support. The concise and comprehensive guide will educate readers on how to implement the powerful new tool using best practices in Web-based application development.

"I am honored to create a solid reference for developers across many industries, as well as my colleagues that write applications for financial services," said Cavaness. "I have already been approached by several academic institutions looking to employ my book as the standard textbook for teaching the latest in Struts technology. It gives me great pride to provide a vehicle to showcase S1's expertise in application development, and make educational contributions to both industry and academia."

In his role as Senior Technologist at S1, Cavaness focuses on long-term strategic technology planning for the S1 Enterprise Platform. Based on a J2EE architecture, the platform enables financial services providers to integrate all delivery channels - Web, phone, branch/agency, call center, ATM/Kiosks - and leverage the interfaces built to its back-end systems. As a result, financial services providers gain a unique ability to share customer data across the organization and obtain the one, consolidated view of each customer's financial world critical to establishing comprehensive, targeted marketing programs and delivering personalized services that foster profitable long-term relationships.

Programming Jakarta Struts is Cavaness's third book. He published Special Edition Using Enterprise JavaBeans 2.0 in September 2001 and Special Edition Using Java 2 Standard Edition in December 2000. In addition to authoring reference books, Cavaness frequently shares his expertise on using Struts to build enterprise applications at various Java User Group forums.
