Is there analogue of Django Messages Framework (or RoR flash messages) in Java?
http://docs.djangoproject.com/en/dev/ref/contrib/messages/
I want to show a message for user one time.
Using Grails, as an example, it is easily possible using the flash scope (like this question denotes : Grails flash scope).
However, notice that any framework would allow you to do that, as that kind of scope is simply an extension of the request : by putting your message in the request attributes, you’ll have it displayed only for the currently processed request.
