Hi Brent,

I'm experiencing a similar problem. I was unable to marshall a
Assertion that was
containing an umarshalled XACMLPolicyStatement, because of the XSAnyImpl
class cast. Now, after changing a bit the namespaces, I have another
error (see below).

I've a method that obtains a PolicySet as org.w3c.dom.Element,
unmarshalls it in a
PolicySetType correctly.

I want to create a new SAML assertion (a Delegated one) containing one
Authentication
Statement, one AttributeStatement and a XACMLPolicyStatement.

// here the code for unmarshalling the policy:

XACMLPolicyStatementTypeImplBuilder stmtBuilder =
(XACMLPolicyStatementTypeImplBuilder)bf.getBuilder(XACMLPolicyStatementType.DEFAULT_ELEMENT_NAME_XACML20);
XACMLPolicyStatementType stmt =
stmtBuilder.buildObject(SAMLProfileConstants.SAML20XACML20_NS,

XACMLPolicyStatementType.DEFAULT_ELEMENT_LOCAL_NAME,

SAMLProfileConstants.SAML20XACMLASSERTION_PREFIX);


UnmarshallerFactory unmarshallerFactory =
org.opensaml.xml.Configuration.getUnmarshallerFactory();
Unmarshaller policyQueryUnmarshaller =

unmarshallerFactory.getUnmarshaller(PolicySetType.DEFAULT_ELEMENT_NAME);
PolicySetType p;
try {
p =
(PolicySetType)policyQueryUnmarshaller.unmarshall(this.policy);
stmt.getPolicySets().add(p);

} catch (UnmarshallingException e1) {
throw new IdentityProviderException(e1);
}

assertion.getStatements().add(stmt);


// end here

// here the code for Marshalling everything:
MarshallerFactory marshallerFactory = Configuration
.getMarshallerFactory();
Marshaller marshaller = marshallerFactory
.getMarshaller(Assertion.DEFAULT_ELEMENT_NAME);

try {
assertionElement = marshaller.marshall(assertion);
} catch (MarshallingException e) {
throw new IdentityProviderException(e);
}


the error is:
