Subject activemq throws exception on tomcat stop log4j related.
Date Fri, 13 Apr 2007 22:22:19 GMT

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

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.
