activemq throws exception on tomcat stop log4j related.
Hello,
i am experiencing same problem that was described in this thread
http://www.nabble.com/active-mq-exceptions-%28when-tomcat-server-is-stopped%29-tf3367534s2354.html#a9369314
tomcat version 5.5.17
activemq version 4.1.0
i am using activemq package to send/recieve messages in webapp - the broker
is configured as separate service.
when tomcat stops, in ~ 1 sec there is an exception in std.out
INFO: Stopping Coyote HTTP/1.1 on http-80
Apr 13, 2007 2:54:04 PM org.apache.catalina.core.AprLifecycleListener
lifecycleEvent

Disconnected from server
I made sure to close all open connections/listeners on appication stop, but
it had no effect.
I also copied log4j.properties from activemq distribution to WEB-INF/classes
but it had no effect.
webapplication is using commons-logging that wraps log4j - i dont know if it
can have anything to do with it.

Apparently, i did not release the listener appropriately. I was stopping
connection insteadof closing. Once that was fixed, the problem went way.
