It helps to read the fine javadoc for org.apache.coyote.ajp.AjpAprProtocol.

In there you will find a protected string called requiredSecret (much like Tomcat 7.x).

Indeed, changing request.secret to requiredSecret when loading the native libraries eliminates
the warning.

However, a cursory glance at the online documentation didn't reveal any mention of this requirement
for the AjpAprProtocol. It's not a problem for Tomcat 7.x obviously since this is the same
attribute for both AprProtocol and AjpAprProtocol.

However, for Tomcat 6 this presents an issue.

So a note when loading the native libraries, using AjpAprProtocol, and Tomcat 6 with the "secret"
attribute:

Change request.secret="somesillypassword" on the AJP/1.3 connector definition to requiredSecret="somesillypassword".

Sorry for the bandwidth.

. . . . just my two cents.
