We will now create the entity class for Course, using Eclipse JPA tools:

1. Right-click on the CourseManagementEJBs project and select JPA Tool | Generate Entities from Tables:

2. Select the Course table and click Next. Click Next in the Table Associations window. On the next page, select identity as Key generator:

3. Enter the package name. We do not want to change anything on the next page, so click Finish. Notice that the wizard creates a findAll query for the class that we can use to get all courses:

@Entity 
@NamedQuery(name="Course.findAll", query="SELECT c FROM 
 Course c") 
public class Course implements Serializable { ...}
