How can a web.xml parameter be read inside a bean?

Question

Java

You need to get the <session-timeout> value from web.xml inside the bean.

There is an armor-piercing method - to parse web.xml, but it does not differ in elegance. Maybe there are some alternative methods?

Or, specifically for session timeout, is it possible to read the actual value from somewhere else?

We are talking about EJBs, not Java Beans (POJOs).

Answer 1

HttpSession session = request.getSession();
session.getMaxInactiveInterval();
But what if "someone" changes it?
