JPA Annotation Processor

Annotation processor that create support classes for JPA annotated classes.

Table Module

The processor creates a Stateless Session Bean that represents the table module class. The table module design pattern represents a single instance that handles the business logic for all rows in a database table or view.

In the traditional design pattern, a table module represents a single model; as generated by this processor, the table module represents a single entity graph that may span one or more tables.

The generated class provides support for CRUD operations via

• save(EntityType) which creates or updates an entity
• remove(EntityType) which removes an entity from the database
• getById(EntityIdType) which reads a single entity from the database

In addition, it creates a new method for each @NamedQuery to ensure the method is called correctly at compile time rather than at run-time.

For non-standard operations, any public static method that has an EntityManager as it's first parameter will have a mapping in the generated code where the entity manager is passed in. Annotations are not copied over for the non-standard operations.
