IT Mill will present Vaadin at Jfokus on January 27th, 2010.  Come and see how Java-only web applications are built with Vaadin at our booth #14. Also, don't miss the presentation by Joonas Lehtinen on "RIA Security - Broken by Design":

"Rich Internet Applications (RIA) provide desktop-like usability with web deployment model. The benefits of this combination are obvious and RIA is now common a choice for the presentation layer in many applications. Unfortunately, moving logic from the server to an untrusted client may open up security holes that would not be present in the page-oriented "Web 1.0" architecture. In this presentation we will take a look at client- and server-side RIA architectures from the security angle, identify some of the most common security problems and discuss strategies for avoiding them. We'll go through some example applications implemented in both architectures and demonstrate the problems. Java-based RIA frameworks, Google Web Toolkit and Vaadin, are used in the examples, but the demonstrated principles are applicable to most other frameworks and languages as well."
