Your component is very very good for a normal vaadin application. It’s easy to use and fast. But doesn’t work with vaadin spring application, with spring security. I think that SimpleFileDownloader uses push server function, but spring security doesn’t permit to pass (I think…!).Configuration in spring security is:
.antMatchers(“/vaadinServlet/PUSH/**”)
.permitAll()
but nothing.
Any ideas? Thanks

Hi Vittorio!
Thank you for your feedback! I’m not really sure what’s wrong with push, but maybe this topic can help?

And We are using this component in one project with spring security and we don’t have any problems. Here is some settings which maybe can help:

MainUI.java

@Push(value = PushMode.AUTOMATIC, transport = Transport.WEBSOCKET_XHR)

pom.xml

<dependency>
	<groupId>com.vaadin</groupId>
	<artifactId>vaadin-push</artifactId>
	<version>${vaadin.version}</version>
</dependency>

But we are using version: 2.0.2, so, maybe there is some issues in 2.1 of this component.

These are two eclipse project (very simple): the first one (prova) is a normal vaadin project (eka new > maven project > vaadin archetype; the second initalized with “spring boot initalizr” 1.5.19 (for vaadin 8).
The first work ok, the second NO.
