We have a EJB project that contains about 10 EJBs that are common to most of our web \
and client applications. As the EJB are generic, so to speak, this is packaged and \
deployed as the only thing in the ear file. Everything works fine except for when we \
need to change any of these EJBs and redeploy. When we redeploy, everything appears \
to redeploy properly but the webapps then start generating class cast exceptions and \
the only way to fix it is to restart jboss.  This happens on our single jboss server \
and the 10 clustered machines we have (running jboss4.0.1sp1 on gentoo with one the \
machines set-up as loadbalancer using mod_jk and apache).

Is this expected behaviour? 
What is standard practice for this sort of common code. I am at a loss as to how we \
can deploy to a live enviroment without any impact on the users and client \
applications.  I thought that this is what hot deployment is all about but it doesn't \
seem to work.

BTW all the EJBs are stateless session beans that just provide glue between web \
apps/clients and the Business Classes (using Data Factory pattern).
