First of all 5.5.12 is very outdated and also very early in the 5.5 release cycle.
You need to add 'tomcatAuthentication="false"' in the Connector element for your AJP connector. The connector you showed us above is
- an https connector
- a comment and not active
At least two good reasons, why this is not the right one. The AJP Connector is the one, which uses port 8009 in the default configuration and which you can identify by 'protocol="AJP/1.3"'.
