This table lists the properties of the Entity Class page of the Create JPA Entity wizard.

Property | Description | Default
--- | --- | ---
Project | The name of the JPA project. |

Java Package | The name of the class package. |
Class name | The name of the Java class. |

Inheritance

Because the wizard creates a Java class with an `@Entity` notation, the Entity option is selected by default.

Select Mapped Superclass if you defined a superclass.

To add an `@Inheritance` notation to the entity, select Inheritance and then select one of the inheritance mapping strategies (described in JSR 220):

- `SINGLE_TABLE` -- All classes in a hierarchy as mapped to a single table. This annotation is without an attribute for the inheritance strategy.

- `TABLE_PER_CLASS` -- Each class is mapped to a separate table.

- `JOINED` -- The root of the class hierarchy is represented by a single table. Each subclass is represented by a separate table that contains those fields that are specific to the subclass (not inherited from its superclass), as well as the column(s) that represent its primary key. The primary key column(s) of the subclass table serves as a foreign key to the primary key of the superclass table.

Entity

XML Entity Mappings | Select Add to entity mappings in XML to create XML mappings in `orm.xml`, rather than annotations. Use the Mapping file field to specify the file to use. By default, mappings are stored in the `META-INF/orm.xml` file. |
