Trying to Migrate from Primefaces PUSH to JSF Push(Websocket), While trying out JSF Push in Java project JSF Push works fine as expected.

But when trying in Spring application I'm getting the below exception

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'pushBean': Unsatisfied dependency expressed through field 'clock'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'javax.faces.push.PushContext' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@javax.inject.Inject(), @javax.faces.push.Push(channel=clock)}

Project structure looks like this.

Below is my xml configs

PushBean.class

@Component
public class PushBean implements Serializable
{
    @Inject
    @Push(channel = "clock")
    private PushContext clock;

    public void clockAction()
    {
        Calendar now = Calendar.getInstance();
        String time = now.get(Calendar.HOUR_OF_DAY) + ":" + now.get(Calendar.MINUTE) + ":" + now.get(Calendar.SECOND);
        clock.send(time);
    }
}

Please suggest whether I'm missing any configurations in order to resole this issue and get JSF Push working?
