Using relationship components  How it works

Chapter 28: Configuring Persistence for Stateful Session Components

Stateful components collect client session data over successive client method invocations. Normally, state data is stored in memory using fields in the implementation class. However, instances of a component coded this way can run on one server only, and cannot support load balancing or failover. Using persistent state storage allows your component to participate in failover and load balancing. EAServer also uses database storage to support the EJB session bean passivation and activation mechanism.
