Mapping file for Dept class is

Hibernate documentation says following.

The {cat.*} and {mother.*} notation used above is a shorthand for "all properties". Alternatively,
you can list the columns explicitly, but even in this case Hibernate injects the SQL column aliases
for each property.



But it is not working as documented in hibernate reference.

ORA-00904: "DEPT2"."DEPTNAME": invalid identifier

check your column name in the mapping file/model class.

Mapping seems to be okay, check the table instead. Is the column there?

{dept1.*} <==> d1? Try: "{d1.*}... FROM Dept d1"

BTW: Don't crosspost... I read your post in the hibernate forum some minutes ago.
