Does @JoinTable has a property of "table" or not?

    @JoinTable(
            table=@Table(name="BoyFavoriteNumbers"),
            joinColumns = @JoinColumn(name="BoyId")
    )
    @Column(name="favoriteNumber", nullable=false)

However, when I put this in practice, I just found that @JoinTable has no "table" property, instead it has a "name" property to specify the table name. But I need "table" property to specify indexes.

What's going on here? I'm almost driven crazy!


No, it doesn't, this sample is not accurate. Just in case, the @IndexColumn annotation that you see in this sample has nothing to do with a database index, it is used to store the index number of an element in an indexed collection. But I guess you're aware of that.

Actually, I'd suggest to raise a Jira issue specifying your use case and your database dialect (it seemts that generating an index on the FK works with some dialects, like MySQL, but doesn't with say Oracle).
