I am looking for an example that SessionMap should be used instead of Map. In the Struts 2 Getting Started HTTP Session tutorial ( https://struts.apache.org/getting-started/http-session.html), HelloWorldAction.java used private Map<String, Object> userSession;
I used SessionMap to replace Map. i.e. private SessionMap<String, Object> userSession; I got the same result after I compiled & executed the modified program, so this is not an example to show the difference between SessionMap and Map.
