Hibernate: fetching a set of objects in an entity mapping

I've got an entity Case that has an id CaseId (unfortunately a string due to compability with a legacy system). This id is foreign key in the table Document, and each Case c开发者_如何学Can have many documents (onetomany). I've put the following in my Case entity:

@Id
@Column(name = "CaseId", length = 20, nullable = false)
private String caseId;

@OneToMany(fetch=FetchType.EAGER)
@JoinColumns ( {
    @JoinColumn(name="caseId", referencedColumnName="CaseId")
} )
private Set<Document> documents;

The table for Document contains "CaseId varchar(20) not null". Right now, in the database, all cases have six documents. Yet when I do myCase.documents().size, I only ever get a single document. What should I do to get all the documents?

Cheers

The mapping looks correct. But it would be interesting to see:

• the Document entity (and its equals/hashCode)
• the SQL performed (see this previous answer to activate SQL logging)
