Backend meets Frontend: Log in and log out of a web application with Vaadin

One big little thing about every web application is log-in and log-out. Also, the application should not simply throw the user out just by pushing the reload button. How this works with Vaadin shows this part of "Backend meets Frontend".

How to start

To play with this you only have to start the main - method from the class org.rapidpm.vaadin.helloworld.server.Main and go with your browser to the address: http://localhost:8080/

Ok, you got your first Vaadin "Hello World".
