A session bean encapsulates business logic that can be invoked programmatically by a client over local, remote, or web service client views. More specifically, a stateless session bean does not maintain a conversational state with the client, so it is mostly used as a service(e.g. rest api, persistence-retrieval) and does specific job without the need of keeping a state.
