Envas takes care of managing both the user interface in the browser and the AJAX communications between the browser and the application running in the station's JVM. You do not need to learn and deal directly with browser technologies, such as HTML or JavaScript. Because all the client-server communications are managed behind the scenes by Envas, you can concentrate on the application logic.
