OpenSAML user discussion

I'm not sure and I'm not able to debug on that system. Here is the complete method:

public ClaimIdentity getID(Element elem, PrivateKey pk) throws JICException {
        UnmarshallerFactory umf = Configuration.getUnmarshallerFactory();
        Unmarshaller unmarshaller = umf.getUnmarshaller(elem);
        try {
            log.debug("attempting to unmarshall DOM representation of SAML token.");
            XMLObject xmlobj = unmarshaller.unmarshall(elem);
            return getID(xmlobj, pk);
        } catch (UnmarshallingException e) {
            throw new JICException("error unmarshalling SAML assertion", e);
        }
        
    }

If the element would be null, would the code "Unmarshaller unmarshaller = umf.getUnmarshaller(elem);" work? In fact, this code is not from me, but from the JInfoCard framework. Its the class de.fraunhofer.fokus.jic.framework.impl.FrameworkImpl.

cheers,

nico
