Package org.fryske_akademy.services Description

This package contains interfaces and base classes for the development of crud (EJB/CDI) beans. The goal is to provide support for dynamic queries, named queries, lazy loading, write operations (including batch) and at the same time deal with intricacies of EntityManager and Transactions. The preferred usage is Local Stateless session bean injected in CDI controller beans. The controller beans may be passivation capable, in that case a field holding a reference to a stateless session bean should be transient and a private method readObject should initialize it, see Util#getBean. Read and write operations are completely separated in the interfaces, which allows for optimization and extra security. EJB is required for declarative security to work.
