Hi all,

I am using Spring with Hibernate 3.1. An ClassCastException is throw in the follwoing code:
HibernateTemplate temp = getHibernateTemplate();
Object load = temp.load(FormSubmission.class, submissionId);
return (FormSubmissionInterface) load; (Exeption occure this line)

In debug mode, I can see the load=FormSubmissonInterface$$EnhanceByCGLIB$$



My mapping file is:


<class name="com.abc.FormSubmission"
table="form_submission"
dynamic-update="false"
dynamic-insert="false"
proxy="com.abc.FormSubmissionInterface"
>
<id name="id" column="id" type="java.lang.Long">
<generator class="native"></generator>
</id>
<property name="submissionDate" type="java.util.Date" update="true" insert="true" access="property" column="submission_date"/>
</class>


I assume hibernate will generate a class implements the interface. How can the casting throw an exception??
Any help much appriciated !

You should not declare load as an Object. Instead, declare it as an interface:

FormSubmissionInterface load = temp.load(FormSubmission.class, submissionId);

Hi imchi,

HIbernateTemplate.load actually return a Object type value.
