This app demonstrates the use of two major Java frameworks, Vaadin and Spring, seamlessly together.

The application follows the Model-View-Presenter pattern. Data model is represented by two classes – Task, which holds data of a task, and TaskRepository, which acts as a task repository. There is only one View-Presenter pair, TaskView and TaskPresenter.

To demonstrate the use of Spring Web Services library, the application implements one more feature – the IP address of a user is looked up in GeoIP database and the user's country is logged into standard output. Logging is provided by LoggingService, GeoIP lookup by GeoIPService.

In order to be able to run this application, you must have these dependencies installed:

• Java 1.8 or higher
• Maven

For running the TestBench tests, you also need:

• Google Chrome
• ChromeDriver for Selenium

Before you build the application, you need to either disable TestBench tests (in case you don't want to use them) or correctly set the ChromeDriver path. In that case, please see src/test/java/cz/jkapoun/todo/tests/AppIT.java file.
