Friends..

Finding difficult in calling the Oracle 10g stored procedure in hibernate.
the scenario is
My Oracle stored procedure returning a String which is something like
(2001,2002,2003) which cannot be mapped to any other Class objects/properties.
Just like a error number.

Input arguments is one integer and one varchar.
How should i map that Return String object in the hibernate mapping file. How should i call in the hibernate.?
Using NamedQuery?

I have tried to map the return type="scalar" in the hibernate mapping file but its not working. GEtting null values.

Please help me in this topic since am struggling for more than a week to resove this
