Hi Martin.
Thank you for your answer.
If I have understood correctly, I use Http11Protocol Connector, as it is
default connector for attribute protocol and it isn't set in my
server.xml (I wrote full listing of this file it in my first letter).
And this is clear from the line of the log of catalina.out:
...
Mar 5, 2009 9:32:46 PM org.apache.coyote.http11.Http11Protocol start
INFO: Starting Coyote HTTP/1.1 on http-123.123.123.123-50002
And I don't have attribute executor anywhere.
