Hi Gavin, Frankly, I don't really know how to set session timeout. I tried to add the following code in web.xml: | <session-config> | <session-timeout>3</session-timeout> | </session-config> Then I login into system, after having waited for a while. I got the following exception. My destroy code is set in a super class which is extended by a SFSB. | @Destroy @Remove | public void destroy() { | | } The exception:2006-12-03 22:17:13,781 WARN [org.jboss.seam.contexts.Contexts]
