This is all in the User's Guide. You must specify properties in the Server.xml file on the Load Balancer and all Servers to configure the desired load-balancing functionality. Open the Server.xml file in a text editor and add the desired properties to the <Properties> section at the end of the file. All of the properties are listed in the Guide.
In this case, you could use this property with the example application you created on the client. As an example, I included 3 applications to load balance. You could just allow 1.
I hope this helps.
(Optional) A comma-separated list of
applications to include in bandwidth and
connection load-balancing calculations. Leaving
this value blank includes all applications on the
Server automatically. Any applications specified
in loadbalanceApplicationsExclude override
