DB commit causing CORBA exception

Hello,

I am using the following code to make an entry into the database :-

         DataServiceTransaction dtx = DataServiceTransaction.begin(true); 
         dtx.setSendChangesToAdapter(true);
         Currency c1 = new Currency();
         c1.setCurrencyCode("ABC");
         c1.setCurrencyName("Dummy Currency");
         c1.setCurrencyLastUpdated(new Date());
         c1.setCurrencyId(new Integer(1)); 
         dtx.createItem("TraderWorkStation.Currency", c1); 
         dtx.commit();

The model has the following DMS annotations, while the entry is being created but there is a CORBA exception as shown below, pls advise

annotationname="DMS">

<itemname="datasource">java:comp/env/ALGODB</item>

<itemname="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</item>

<itemname="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.JOTMTransactionManagerLookup</item>

<itemname="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</item>

<itemname="ServerGeneratedEntities">false</item>

</annotation>
