Using SSL with JBoss/Tomcat: key pair selection

A few days ago i spend time searching how to configure JBOss/Tomcat bundle for SSL. You 
 can find many documents or tips such as SSLSetup (JBoss WIKI)
 or Using SSL With JBoss. But my problem
 was, that i had keystore with multiple keys. I have been through the many documentations and 
 have not found any mention about setting appropriate key pair or more precisely his alias.

It was very frustrated to see many simillar connector definitions without any change. Bad news 
 was missing DTD in XML configuration file and missing this type of parameter in official documentation
 SSL Configuration HOW-TO 
 and in The Coyote HTTP/1.1 Connector reference.
 Fortunately helped me Mr. Google and found outlandish patch comment 
 by Doug Barnes.

These undocumented parameters are keyAlias and keyPass (if you have different password than keystore password).
