Change Session Timeout during runtime in Struts2

I know that I can set the session timeout in web.xml in the <session-config> section. What I need now is to change this setting dynamically during runtime, i.e. call a method that overrides the web.xml setting if needed.

Any ideas? I found nothin开发者_运维知识库g so far.

Found it! As described in JBoss Session Timeout one can use HttpSession.setMaxInactiveInterval(int seconds).
