I was clustering CAS (Central Authentication Service). I used the <Cluster> tag from the Clustering CAS page. But, there is also a <Cluster> tag in the server.xml that is commented out. Either one looked like they would work with the appropriate setup. We are using Tomcat 5.5.23, which should not be too different from Tomcat 5.5.25.
It looks like multicasting is not working on your system.
