OK, I Googled all over for this and found literally nothing. So here goes...
I'm using Hibernate 3.4 implementation of the JPA.
Q: Is it possible to map a collection of Java 5 enum instances using EnumType.ORDINAL?
I have a class with the following mapping (PaymentMethod is a java enum):
Code:
@CollectionOfElements
@JoinTable(name="ListingPreferencesPaymentMethods", joinColumns=@JoinColumn(name="listingPreferencesEntityId", referencedColumnName="entityId"))
@Column(name="paymentMethod")
@Enumerated(EnumType.ORDINAL)
private Set<PaymentMethod> paymentMethods;
When trying to access this in a test:
Code:
prefs.getPaymentMethods().size();
This blows up. It appears as if the @Enumerated annotation isn't used in this context. Is this true?
Here's the exception:
