/**
 * This Class acts as remote local interface for the AlertsBean which is a
 * local EJB Object. UserAccount is an Entity Object. Every User Account
 * can have multiple Alerts and this 1:N relationship between User Account
 * Entity Bean and Alerts Bean is managed by the EJB Container.
 *
 * This new feature called CMR (Container Managed RelationShips) is a new
 * feature added in EJB 2.0 Specification.
 *
 * Note that the JSP/Servlet Clients never invoke the Local Objects directly.
 * Session Bean namely 'UserManagementSessionFacadeBean' invokes the methods
 * on this Local Objects on the behalf of outside clients.
 * This pattern is called as Session Facade Pattern
