Vaadin is Java framework for rapid development of web applications in server-side environment. It abstracts the underlying document and state transfer technologies, allowing web applications to be developed in Java. Vaadin leverages the full power of GWT, a Java to Javascript compiler, making it possible to develop the entire web application stack and new client-side components without leaving the Java environment. Attendees will get an overview of Vaadin 7.1, a closer look at the Vaadin architecture behind the scenes of the framework. New features of Vaadin 7.2 will also be discussed. Language: English
