using List<T> in a OneToMany relationship

[bill.burke]

Currently, only Set and Collection are supported.

You must also use a Java generic as the EJB 3.0 deployer looks at the type of the generic to determin the other side of the OneToMany relationship.

So, it should be

@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
@JoinColumn(name = "language_oid")
public Set<Word> getWords() {
return words;
}

public void setWords(Set<Word> value) {
words = value;
}
