[jboss-user] [EJB 3.0] - "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
