Hi, I'm new in mod_cluster and I'm try to run the Load Balancing Demo Application.

I'm using:

mod_cluster-1.1.1.Final-bin.tar.gz

mod_cluster-1.1.1.Final-windows-x86-ssl.zip

the httpd server included in mod_cluster-1.1.1.Final-windows-x86-ssl.zip

and a Tomcat 6.0.32

I followed the steps from chapter 2 in the mod_cluster documentation but when I click Start in the Load Balancing Demo Application the following exception is thrown:

java.lang.NullPointerException

I think the problem is that the method findService() is returning null.

Do you know why this is happening?

Thanks!
