Hi Sandeep,
have you tried to remove the mapping for rules.

Hi All,
I have created a Castor mapping file for marshalling (creating XML text)
for an Object called ClientDcl.
ClientDcl has a field '_roles' of type Set. Through debugging I have
found that trying to expand the _roles node in Eclipse debugger
variabled view gives me a Hibernate exception. So very obviously even
Castor gets that when it tries to walk down the ClientDcl object and
it's field _roles.
To prevent the above and letting Castor marshall the object to XML, I
tried to set the _roles field as 'transient' as following:
/************************ castor-mapping.xml *************************/
<class name="com.adminserver.dcl.ClientDcl" identity="_clientGuid"
access="shared"
auto-complete="true">
<field name="roles" type="com.adminserver.dcl.RoleDcl"
get-method="getRoles"
set-method="setRoles" collection="set" transient="true">
<bind-xml name="Roles" node="element"/>
</field>
</class>
/*********************************************************************/
But, when I try to marshall the ClientDcl using the following code, I
still get the Hibernate exception and no marshalled XML!!
/********************* Code to Marshal to XML *************************/
Marshaller marshaller = new Marshaller( new PrintWriter( System.out) );
Mapping castorMapping = new Mapping();
InputSource inputSource = new
InputSource( getClass().getResourceAsStream( "/castor-mapping.xml" ) );
if( null != inputSource ){
castorMapping.loadMapping( inputSource );
marshaller.setMapping( castorMapping );
Marshaller.marshal( result, new
PrintWriter( System.out) );
}
