Re: automatically refresh data in web page

Server-Sent Events by using elemental-dom example: https://github.com/axls/gwt-spring-boot-samples/blob/master/gwt-spring-boot-sample-sse/src/main/java/gwt/springboot/sample/sse/client/ApplicationEntryPoint.java

WebSocket by using elemental-dom example: https://github.com/axls/gwt-spring-boot-samples/blob/master/gwt-spring-boot-sample-websockets/src/main/java/gwt/springboot/sample/websockets/client/ApplicationEntryPoint.java

Very simple examples, but may be usefull as starting point. And examples contains both, client and server code in one project, but this is not recommended due to leaking GWT dev-dependencies into server classpath.

Hi Thomas

For my information. What would you use on the gwt side for EventSource.

Fwiw, WebSocket is for bidirectional communication. Have a look at Server-Sent Events (aka EventSource), https://caniuse.com/#feat=eventsource, it might be easier to integrate in your server stack (it's HTTP, whereas WebSocket is a whole different protocol that needs support at the web server level as well as all reverse-proxies)
