Creating a JPA Entity

Use this procedure to create a JPA entity:

-
From the Navigator or Package Explorer, select the JPA project and then File > New > Other. The Select a Wizard dialog appears.
-
-
Selecting the Create a JPA Entity Wizard
-
-
-
Select Entity and then click Next. The Entity Class page appears.
-
-
The Entity Class Page
-
- -
Complete this page as follows:
-
- -
  Select the JPA project in the Project field.
  -
- -
  In the Source Folder field, select, or enter, the location of the JPA project's src folder.
  -
- -
  Select, or enter, the name of the class package for this entity in the Java Package field.
  -
- -
  Enter the name of the Java class in the Class name field.
  -
- -
  If needed, enter, or select a superclass.
  -
- -
  If needed, complete the Inheritance section as follows (these properties are optional):
  -
  - -
    Accept the Entity option (the default) to create a Java class with the @Entity option.
    -
  - -
    Alternatively, select Mapped superclass (if you defined a super class).
    -
  - -
    Select Inheritance and then select one of the JSR 220 inheritance mapping strategies (SINGLE_TABLE, TABLE_PER_CLASS, JOINED).
    -
  - -
    Select Add to entity mappings in XML to create XML mappings in orm.xml, rather than annotations.
    -

Click Next to proceed to the Entity Properties page where you define the persistent fields for the entity.

Alternatively, click Finish to complete the entity.

  -
2. -
  Accept Use default (the default setting) to use the default value for the name of the mapped table. Entering a different name results in adding the @Table notation with its name attribute defined as the new table (@Table(name="TableName")).
