hm, another attempt to send an attachement.
-----Original Message----- From: Ilyschenko, Vlad Sent: Sun 2/13/2005 1:32 AM To: [email protected] Cc: Subject: RE: dodgy session class thanks for your reply Peter. unfortunately none of the applications has explicitly configured sessions manager. I have managed to consistently reproduce the problem. The problem involves two webapps, app1 and app2. App1 is distributable. App2 contains a filter that forwards requests to app1. As it turns out all sessions created via filter are instances of StandardSession! This is with app1 being distributable and with cluster session manager. Making app2 distributable doesnt seem to have any effect on the sessions that are being created in app1 context. I've attached a test case with two sample webapps, to run them you just have to make sure crossContext is enabled for app2 and context of app1 is actually called "/app1". App1 does some nasty hack to display what Class is actually hiding behind session facade, so you would have to excuse me for that. Another thing that i've noticed along the way: if a request goes to app1 via filter in app2 two sessions are created, one for each context. Filter in app2 does not create sessions explicitly (as you will see from the example) and session would not be created for app2 context if filter didnt forward requests to "app1" context. The question is why session gets created implicitly in context of "app2"? It is not that I cannot live with it, just cant think of a logical explanation to this. Ideas anyone?
