Mastering XPages: A Step-by-Step Guide to XPages Application Development and the XSP Language, 2nd Edition

Description

IBM's Best-Selling Guide to XPages Development–Now Updated and Expanded for Lotus Notes/Domino 9.0.1

XPages instantly revolutionized Notes/Domino application development, and the newest versions deliver unprecedented performance and flexibility. Now, the popular insider's guide to XPages development has been updated and expanded to reflect all these improvements, through IBM Notes/Domino 9.0.1 and beyond.

Three key members of the IBM XPages team have brought together comprehensive knowledge for delivering outstanding solutions. They have added several hundred pages of new content, including four new chapters. Drawing on their unsurpassed experience, they present new tips, samples, and best practices reflecting the platform's growing maturity. Writing for both XPages newcomers and experts, they cover the entire project lifecycle, including problem debugging, performance optimization, and application scalability.

This second edition of Mastering XPages fully addresses enhancements to the XPages data sources for Domino views and documents; the latest XPages mobile library; the new Domino Designer Server-Side JavaScript debugger; and improvements to integrated technologies such as Dojo and CKEditor.

Nearly every chapter contains at least one downloadable sample application, offering extensive hands-on practice. This guide concludes with complete references to XSP tags, relevant Java/JavaScript classes, and XSP style classes.
