Hi Chad -

Here is the code sample:

XMLObjectBuilderFactory builderFactory = Configuration
                .getBuilderFactory();

Response response = (Response) 
buildXMLObject(Response.DEFAULT_ELEMENT_NAME);
//Filling required values in response like issuer id, etc.

// Creating assertion object
Assertion assertion = (Assertion) 
buildXMLObject(Assertion.DEFAULT_ELEMENT_NAME);
//Filling in the required values like name, subject, conditions, attributes 
etc.

// Generating the signature through signature builder
// Setting the signature to response object

// Marshalling the response
Element authElement = marshall(response);

// Converting to base 64 encoding



---- Sample code for Marshall method

        private Element marshall(XMLObject marshallMe) throws Exception {
                try {
                        MarshallerFactory marshallerFactory = Configuration
                                        .getMarshallerFactory();
                        Marshaller marshaller = 
marshallerFactory.getMarshaller(marshallMe);
                        if (marshaller == null)
                                throw new MarshallingException(
                                                "unable to locate marshaller for 
["
                                                                + 
marshallMe.getElementQName() + "]");

                        // Convert SAML metadata to XML DOM (includes 
signature)
                        return marshaller.marshall(marshallMe);

                } catch (Exception x) {
                        throw new Exception(x);
                }
        }


----- Sample code for base 64 encoding


        private String getBase64SAML(Element authElement) throws Exception {
                try {
                        // Serialize to string
                        DOMImplementationRegistry registry = 
DOMImplementationRegistry
                                        .newInstance();
                        DOMImplementationLS impl = (DOMImplementationLS) 
registry
                                        .getDOMImplementation("LS");
                        LSSerializer writer = impl.createLSSerializer();
                        String str = writer.writeToString(authElement);

                        str = Base64.encode(str.getBytes());

                        return str;
                } catch (Exception x) {
                        throw new Exception(x);
                }
        }


Thanks
