Is it possible to define a spring bean that extends ApplicationListener with access to current request? this way in the onApplicationEvent you can manipulate request attributes as a side effect of an application event firing. This could cause particular messages to be published to the screen as a result in response to the events that occured.
You may see this as a hack (well, ok, you should) but instead of inserting web notion into the application listener, which is doable but requires to extends WebApplicationContext, etc... you could use a ThreadLocal to store the current request and access it in any application listener aware of this ThreadLocal ...
This can be a dirty hack but useful when you don't want to break apis to pass a new parameter...
