[appfuse-user] Does Hibernate support foreign key in String type?

[dev dev]

I have a table A, which has a column X defined as VARCHAR and a table B,
which has a composite key in which one of the columns referred to
table A.Xcolumn. When i map this in Hibernate, it automatically
convert the key into
Integer. It seems to me that Hibernate doesn't support foreign key in String
type or what? Anyone knows ??

Thanks
