http://nagoya.apache.org/bugzilla/show_bug.cgi?id=9367 HttpSessionBindingEvent not thrown for HttpSessionBindingListener objects when session expires Summary: HttpSessionBindingEvent not thrown for HttpSessionBindingListener objects when session expires Product: Tomcat 3 Version: 3.2.3 Final Platform: HP OS/Version: HP-UX Status: NEW Severity: Major Priority: Other Component: Servlet AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] This was reported by a user for TC 3.3. I have found it on 3.2.3 on HPUX as well. The attached code works perfectly on TC 3.2.3 on Win NT 4 SP 6. Fails always (i.e. HttpSessionBindingListener objects never get an unbound event) when sessions expire on HPUX. The following two JSP's demonstrate the bug. Install them in any web- application. Open Monitor.jsp in a browser (it refreshes every 5 secs). Open SessionTest.jsp in another (Monitor should now show the new session) and then close the "SessionTest" browser window. After "session-timeout" minutes, the row should vanish in the "Monitor" browser. It does on Windows. It does not on HPUX.
