AndroMDA EJB Cartridge Profile

This profile contains all elements that can be applied on the model used as the MDA transformation process. These elements are specific to the AndroMDA EJB Cartridge component.

Stereotypes
Stereotypes are the names you sometimes see appear in UML diagrams, they typically look like <<MyStereotype>> and can be applied on any type of UML model element.
Tagged Values
Sometimes it happens you want to add information to the model but there is no clean way of doing it. In those cases you may want to resort to tagged values, but these cases should be considered with caution. A tagged value is something extra, something optional, and the application should run fine without them.

Entity(Back to Stereotypes)
Applied on: class
Produces a CMP EJB entity.
Service(Back to Stereotypes)
Applied on: class
Produces a Session EJB facade for the CMP EJB entities.
Identifier(Back to Stereotypes)
Applied on: Entity attribute
Identifies an attribute as an identifier (primary key).
CreateMethod(Back to Stereotypes)
Applied on: Entity operation
Used to tag an EJB create method.
EntityRef(Back to Stereotypes)
Applied on: A dependency going into an Entity
Used to reference an entity from another entity or service.
ServiceRef(Back to Stereotypes)

Used to reference a service from an entity or another service.
ValueRef(Back to Stereotypes)
Applied on: A dependency going into a ValueObject and out of an Entity
Used to generate an association between an entity and a value object class. Found attributes inside the entity as well as the value object are used to get automatically filled out. The entity will provide the helper method, also for saving a value object to an existing entity.
@andromda.ejb.automaticKey(Back to Tagged Values)
