Mutable interface:
/** * Must be implemented by any SESSION or CONVERSATION scoped * mutable JavaBean component that will be used in a clustered * environment. If this interface is not implemented correctly, * changes may not be replicated across the cluster (depending * upon the servlet engine implementation). * * @author Gavin King * */ public interface Mutable extends Serializable { /** * Get and clear the dirty flag. * * @return true if the instance is dirty and requires replication */
1) what exactly is the definition of a mutable
JavaBean component? seems to me all JavaBean components by default are mutable as per the setter methods, no?
