Hi, For managing transactions (multiple operations in one transaction),the preferred approach would be to use Session Facade pattern i.e., wrapping the entity bean layer in a layer of session beans. You can put the same code in entity bean also but that would make entity bean difficult to understand,maintain, and reuse.Merging application logic with persistence logic will result in poor application design. thanks [ June 17, 2002: Message edited by: snigs ]

Hi, Authentication refers to valid user or not, the registered user or not.Authorization refers to whether the user is authorized to access a particular application/ module or not. Hari
