Value object:
...
public class Xxx{
public java.sql.Date data;
public Xxx(java.sql.Date data){
this.data = data;
}
}
...
HQL:
...
select new Xxx(sc.data) from SomeClass sc
...
Exception:

1 errors occurred while listing (and calling getPathNames).
net.sf.hibernate.PropertyNotFoundException: no appropriate constructor in class: Xxx

I'm sure sc.data is a java.sql.Date in the java code and in the mapping files (type=java.sql.Date)... the sql-type is timestamp and the database is Postgres. Writing and reading from the original class (SomeClass) works fine. If I change the the attribute data in Xxx to java.util.Date the HQL works...

Any Ideas ?

Thanks in advance,

Walter
