Hi,

Our application deals with specific 'type' classes that need to be used instead of int, double etc. For this, I implemented a UserType class that is specifically for use by Hibernate and extends the type classes required by my application so that the hibernate object returned would already be of the type as required by my app.

In code terms...

CUSIP: A String stored in my database
Cusip: A class used to store this cusip value. The entire application expects this class instead of just a plain string.
SBSHibernateCusip: My implementation of UserType that I want the objects to return so that the objects returned by Hibernate can directly be used by my classes.

The classes compile fine but I get the exception stated below when I run my app. Please advise...

Hibernate version:2.1.6

Mapping documents:
*.hbm File
<property
column="CUSIP"
length="9"
name="cusip"
not-null="true"
type="SBSHibernateCusip"
/>

Full stack trace of any exception that occurs:
