EJB relation assembly settings

An EJB relation describes a relationship between two entity beans with container-managed persistence.

The name of the relationship, if specified, is unique within an EJB archive file.

Description

Contains text to describe the EJB relationship role.

Source EJB

Specifies the source of the role that participates in a relationship.

Multiplicity

Specifies the multiplicity of the role that participates in a relation.

Cascade delete

Within a particular relationship, specifies that the lifetime of one or more entity beans is dependent on the lifetime of another entity bean.

Cascade delete can be specified only for an EJB relationship role contained in an EJB relation in which the other EJB relationship role specifies a multiplicity of one.

CMR field

Enables the declaration of a container-managed relationship (CMR) field.

The CMR field describes the bean provider's view of a relationship. It consists of an optional description and the name and class type of the source enterprise bean's role in a relationship.
