Written by

In a client-server architecture, Java applications are most often located on the server side, and web interfaces are created by separate groups of front-end developers using JavaScript. Java does not provide any useful tools to develop modern Web interfaces (Do you still remember what Java applets look like?) — neither in terms of design, nor in terms of the client-server interaction. But what if the entire client-server application was developed using Java?
