RE: How to get the container within an instance event?
Cool! That is exactly what I needed! I was getting miffed because valves got the nice catalina request object while InstanceEvent had to deal with the dumbed down HttpRequest. Now onto a design question: I am implementing a JdbcSessionManager for dealing with non-sticky clusters. We wish to use the DB to store all of our session data when it is not in use. Thanks to Craig's help I was able to figure out how to do the updating of the session data in an InstanceEventListener that catches the AFTER_SERVICE_EVENT. In talking to Filip Hank about his Clustered session manager I was also able to do the database updates in a valve. Which way is preferable? In the InstanceEvent I can just filter out all queries that make this true: default.equals(event.getServlet().getServletConfig().getServletName()) . Filip used the file extensions to create an exclusion list. Other notes: I have had to create my own JdbcSession object instead of subclassing StandardSession because the attributes HashMap is private and I need access to it. (I think) I am serializing the HashMap and storing only that in its own column. My other columns are expire_time, creation_time, app_name, and session_id. I am currently limited to sessions with 8k of data because of the DB limits on VARBINARY but that can change at a later date. --Angus -Original Message- From: Craig R.
