Tomcat 1   Server.xml

<!-- You should set jvmRoute to support load-balancing via AJP ie : -->
<Engine name="Standalone" defaultHost="localhost" jvmRoute="node01" >
        
<!-- Define the top level container in our container hierarchy -->
<!-- <Engine name="Catalina" defaultHost="localhost" > -->


Tomcat 2   Server.xml

<!-- You should set jvmRoute to support load-balancing via AJP ie : -->
<Engine name="Standalone" defaultHost="localhost" jvmRoute="node02" >

<!-- <Engine name="Catalina" defaultHost="localhost" > -->

is not transfered to the 2nd Tomcat.
