Hibernate and Date objects

[Chris Williams]

Hi everyone,

I'm having a frustrating time working with Date objects and Hibernate
with an Oracle database.

I have a Patient class containing a Date field (java.util.Date)

and the mapping in the hbm.xml file:

<property name="regDate" type="date">
<column name="REGISTRATION_DATE" />
</property>

When I try and commit a new object to the database, I get a
ClassCastException with the following backtrace:

java.lang.ClassCastException

Is this something to do with casting (and failing) an java.sql.Date to a
java.util.Date or something similar?

If anyone can shed any light on this, or has had a similar problem, it
would be greatly appreciated!

Cheers,

Chris.
