Chapter 8 Creating J2EE Applications for BEA WebLogic
This section describes the behavior of EJBs and their associated transactions in a WebLogic Server cluster, and explains key deployment descriptors that affect EJB behavior in a cluster.
EJBs in a WebLogic Server cluster operate using modified versions of two key structures: the Home object and the EJB object. In a single server (unclustered) environment, a client looks up an EJB via the EJB's home interface, which is associated with a Home object on the server. After referencing the bean, the client interacts with the bean's methods via the remote interface, which accesses the EJB object on the server.
Note: Failover of EJBs works only between a remote client and the EJB.
