Setting context-parameters programatically when using vaadin-cdi

Question

I annotated my UIs with @CDIUI and dont use web.xml for the binding. But how can I set context-parameters like debugMode, heartbeatIntervall, closeIdleSessions ... ? Is there a way to annotated those features or pass them inside the UI instance? Or do I have to provide a web.xml anyway? What about System.getProperty (the JBoss property handling)? Thanks for any clue.

Try to implement your own DeploymentConfiguration in the following way:

public class ExampleUI extends UI {
    private class ExampleConfiguration implements DeploymentConfiguration {
        @Override
        public int getHeartbeatInterval() {
            return 30;
        }

        @Override
        public boolean isCloseIdleSessions() {
            return true;
        }
    }

    @Override
    protected void init(VaadinRequest request) {
        getSession().setConfiguration(new ExampleConfiguration());
        ...
    }
}

Then you can get context parameters outside ExampleUI class in a standard way:

VaadinSession.getCurrent().getConfiguration().getHeartbeatInterval();
VaadinSession.getCurrent().getConfiguration().isCloseIdleSessions();

I hope this helps.
