I suppose the initial expression for the static field would be like this:
BeanX singleton = ((BeanXHome)javax.rmi.PortableRemoteObject.narrow(
new InitialContext().lookup(path), BeanXHome.class)).create(parms)
but where would this code would be placed. It's no good inside ejbCreate
as ejbCreate is already running on a new instance rather than the singleton.
So how could you implement the singleton portably?

I agree. CICS treats enterprise beans and their helper classes the same
in this respect.
