Hi Claudio,
I am also implementing a setup with CAS 2.1 + Tomcat 5.0.28 +
Jboss-cache and it is setup for clustering, but I haven't come across the
exception that you experienced. Granted my setup isn't working completely
as my replication component does not seem to work (I believe this is just a
configuration issue), but I am wondering if the problem you're seeing is
something I will encounter or are you doing something more unique. You
stated that as long as the <distributable /> tag is present in the
web.xmlthen you don't see the error?
Regards, David
