Hello,
I use hibernate extended Session pattern and everything goes ok until session is not invalidated first time both by application server or by direct calling invalidate();
If application server perform httpSession.invalidate() at the method doFilter from class HibernateThreadExtendedFilter on ‘finally’ section marked line throws exception:
Code:
finally {
log.error("Cleanup after exception!");
// Cleanup
log.debug("Closing and unbinding Session from thread");
sf.getCurrentSession().close(); // Unbind is automatic here
log.debug("Removing Session from HttpSession");
httpSession.setAttribute(HIBERNATE_SESSION_KEY, null); <<<<<<<<<<<<<<< removeAttribute: Can’t do it because session already invalidated!
}
// Let others handle it... maybe another interceptor for exceptions?
throw new ServletException(ex);
}
}
After that I have a trouble with restoring transaction even if new session has been started. Here is my log. I’ve done httpSession.invalidate() (logout in my app) then I try to log in again.

Could somebody tell me what might be the reason of such application behavior? Is it possible to make transaction restore with the session?
Thanks in advance,
