Hibernate mapping between JGeometry & SDO_Geometry

Question

Has anyone figured out how to create a hibernate mapping file for mapping between oracle.spatial.geometry.JGeometry and SDO_Geometry type? Haven't been able to figure out how to do it with UserTypes
for instance I'd like to create a simple class like the following:
import oracle.spatial.geometry.JGeometry;
public class Building {
private Long id;
private String label;
private JGeometry shape;
public Building() {}
with a corresponding hibernate mapping file that would contain something like:
<hibernate-mapping>
<class name="Building" table="BUILDING">
<id name="id" column="ID" type="long">
<generator class="native"/>
</id>
     <property name="label" type="string" length="100"/>
     <property name="shape" type="JGeometry"/>
</class>
</hibernate-mapping>
that would create a create SQL like:
CREATE TABLE Buildings (
     id NUMBER PRIMARY Key,
     label VARCHAR(100),
     shape SDO_GEOMETRY)
     storage (initial 1m);

Hi,
We're specifying the custom type mapping using the OracleCustomTypeMappingAttribute and not in any configuration.
The problem is occurring only on our test server and it has worked fine in the past.
Strangely, our application works fine for a few hours and then the problem starts to occur.
Once it happens, the problem stays until we re-start the web site or IIS.
It's since we've done a completely fresh install of Oracle and .NET on the server so it's something to do with that I suspect.
I can't seem to find any differences between the test server and our development machines however.
I've tried to enable tracing but the trace file grew to over 1.5 gig within 30 mins so it would be impossible to let it run for hours.
Even if we did have enough space, the file would be too big to analyse using any tools I know of.
Any other suggestions would be welcomed.
