"mapped-superclass" element in persistence XML.

[iamar]

Hi everyone,

I am using "mapped-superclass" element in persistence XML and I am getting the following error message: "Reason: java.lang.ClassCastException: $Proxy169", while using @MappedSuperclass notation everything works fine. I must specify that the persistence provider I am working with is Hibernate and JBoss version 4.0.4.

The following is the exact persistence XML:

<?xml version="1.0" encoding="UTF-8"?>
<entity-mappings xmlns="http://java.sun.com/xml/ns/persistence/orm" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm_1_0.xsd" version="1.0">
<persistence-unit-metadata>
<xml-mapping-metadata-complete/>
</persistence-unit-metadata>
<mapped-superclass class="com.fts.domain.ValueObject"/>


<sequence-generator name="CUSTOMER_PK" sequence-name="CUSTOMER_SEQ"/>



<generated-value generator="CUSTOMER_PK"/>









</entity-mappings>

I will appreciate any help.

Thanks a lot
Ilan
