<Engine name ... causes tomcat not to start

[ronb722]

Hi All,
I'm trying to setup load balancing on two separate tomcat servers. When I add the following line to my server.xml file, and restart tomcat, tomcat fails to start (See error below).

I have the same setup on my other server I and I am not having this issue.

Any ideas?
Ron
The line I added is:
<Engine jvmRoute="ngdserv5" name="Standalone" defaultHost="localhost" debug="0">
