Getting a weird classcastexception while casting the object which has many-to-one relationship with the object being retrieved. Spring's hibernateTemplate is being used here.
I tried the following but it did not work:
1. Added lazy="no-proxy" to the many-to-one relation
2. Added proxy="com.sterling.drug.common.domain.AlcoholTestResultSubject" to the AlcoholTestResultSubject.hbm.xml
3. Tried with hibernate version 3.0
I have given the additional details here. Thanks in advance.
Hibernate version:[3.2.0 cr4]
Mapping documents:[
AlcoholScreeningResult.hbm.xml
<hibernate-mapping>
<class name="com.sterling.drug.common.domain.AlcoholScreeningResult" table="AlcoholScreeningResult" schema="dbo" catalog="sttestdb">
<id name="alcoholScreeningResultId" type="int">
<column name="AlcoholScreeningResultId" />
<generator class="identity" />
</id>
<many-to-one name="alcoholTestResultSubject" class="com.sterling.drug.common.domain.AlcoholTestResultSubject" fetch="select">
<column name="AlcoholTestResultId" not-null="true" />
</many-to-one>
<property name="orderNumber" type="string">
<column name="OrderNumber" length="20" />
</property>
