A join table is typically used in the mapping of many-to-many and unidirectional one-to-many associations. It may also be used to map bidirectional many-to-one/one-to-many associations, unidirectional many-to-one relationships, and one-to-one associations (both bidirectional and unidirectional).
When a join table is used in mapping a relationship with an embeddable class on the owning side of the relationship, the containing entity rather than the embeddable class is considered the owner of the relationship.
If the JoinTable annotation is missing, the default values of the annotation elements apply. The name of the join table is assumed to be the table names of the associated primary tables concatenated together (owning side first) using an underscore.
Example: [JoinTable(name="CUST_PHONE")] [JoinColumn(AttributeRef="CUST_PHONE",name="CUST_ID", referencedColumnName="ID")] [JoinColumn(AttributeRef="CUST_PHONE",name="PHONE_ID", referencedColumnName="ID", Inverse=true)] )

Initializes a new instance of theclass
(Optional) determines that this join table belongs to an AssociationOverride definition. If populated, this join table overrides a mapping of a relationship. The joinTable element must be specified if a join table is used in the overriding of the mapping of the relationship. The joinTable element must not be specified if a foreign key mapping is used in the overriding of the relationship.
(Optional) The catalog of the table. Defaults to the default catalog.
(Optional) The name of the join table. Defaults to the concatenated names of the two associated primary entity tables, separated by an underscore.
(Optional) The schema of the table. Defaults to the default schema for user.
