Hi again, I found that I've sent wrong log when stopping the server
(second log in my earlier post). The correct is:
INFO: Pausing Coyote HTTP/1.1 on http-8080
2007-11-16 10:50:35 org.apache.catalina.core.StandardService stop
INFO: Stopping service Catalina
DEBUG 2007-11-16 10:50:35,625 test.SessionBean Session will passivate
DEBUG 2007-11-16 10:50:35,640 test.MyServletContextListener Context destroyed
2007-11-16 10:50:35 org.apache.coyote.http11.Http11Protocol destroy
INFO: Stopping Coyote HTTP/1.1 on http-8080
Best regards,
Jacek
