Ensure that the following line is commented out. You may have already
done this
<!-- Define the top level container in our container hierarchy -->
<!-- <Engine name="Catalina" defaultHost="localhost"> -->
And uncomment
<Engine name="Standalone" defaultHost="localhost" jvmRoute="worker1">
Hope that will help.
