I have a JPA code with OneToMany relationship. A Customer has a list of Item to check out. However, the code continue to generate StackOverflowError .

I am trying to perform a merge(entity) using eclipselink, and I would like to indicate to eclipse if that will be an update or insert, so it does not have to perform the initial select query.

I have the following situation: (source: kawoolutions.com ) JPA 2.0 mappings ( It might probably suffice to consider only the Zip and ZipId classes as this is where the error seems to come from ): @Entity @Table(name = "GeoAreas") @Inheritance(strategy = InheritanceType.JOINED) @DiscriminatorColumn(name = "discriminator", discriminatorType = DiscriminatorType.STRING) public abstract class GeoArea implements Serializable { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "id") protected Integer id; @Column(name = "name") protected String name; ... } @Entity @Table(name =

I have foreign key inside my Customer table. @JoinColumn(name = "DISCOUNT_CODE", referencedColumnName = "DISCOUNT_CODE") @ManyToOne(optional = false) private DiscountCode discountCode; I have a form that contains all fields of this table (including the foreign key discountCode and its description from the other table). I want to be able to show a message that this foreign key does not exist in case that the user entered an input that does not exist in the foreign key table.

I'm currently having this issue which I don't have before I migrated to eclipse-jee-kepler. What I have: I have 2 classes, base and the extending class: public abstract class BaseEntity implements Serializable { @Id @GeneratedValue(generator = "ID_GENERATOR") @Column(name = "ID") private Long id; } @Entity @Table(name = "CUSTOMER") @SequenceGenerator(name = "ID_GENERATOR", sequenceName = "CUSTOMER_SEQ") public class Customer extends BaseEntity { } Before I don't have this validation error but now eclipse is throwing it. I can compile, build and deploy successfully but the error marker is
