Question About Clustering EJB's

[Oisin Kim]

Hi All,
I've noticed that some asked for help on how-to cluster EJB's and got no 
reply. I thought I read in the documentation that this isn't possible, is 
it?? 
Or has someone got a workaround that wouldn't involve sharing a database, 
hard disk or anything that would be a single point of failure?
Thanks,
Oisin Kim
