This indeed can be an issue. <vendor> GemStone/J lets you share http session state through its persistent cache so that load balancing can be completely dynamic (i.e. not sticky). </vendor> You could do the same thing yourself by serliazing EJB handles to a data store external to the servlet engine (i.e. don't use http session state). But this would be a fair amount of work.
