Laszlo in Action is the first comprehensive guide to the Laszlo system and its language LZX. OpenLaszlo is an increasingly popular open-source platform for the development and delivery of rich internet applications across multiple platforms: Flash, DHTML, and J2ME. The dramatic emergence of Ajax over the past year was a first step in the transition from page-oriented HTML web applications towards more full-featured rich internet applications. OpenLaszlo provides another important step in this continuing evolutionary process through the increased productivity resulting from LZX’s declarative approach. It provides developers with the tools to create web-based applications offering the usability and interactivity associated with desktop applications, and the low costs associated with web-based deployment. The cross-platform nature of Laszlo LZX applications allows source code with only minimum modifications to run natively on all popular web browsers, on all desktop operating systems, on the Flash platform, and other platforms in the future.
