How to add x509Data tag and keyInfo tag in Subject tag in saml2

I am using the following code to generate the below saml assertion:

        SAMLObjectBuilder confirmationMethodBuilder = (SAMLObjectBuilder) builderFactory.getBuilder(SubjectConfirmationData.DEFAULT_ELEMENT_NAME);
        SubjectConfirmationData  confirmationMethod = (SubjectConfirmationData) confirmationMethodBuilder.buildObject();
        DateTime now = new DateTime();
        confirmationMethod.setNotBefore(now);
        confirmationMethod.setNotOnOrAfter(now.plusMinutes(2));

    //SAMLObjectBuilder keyInfoBuilderMethod = (SAMLObjectBuilder) builderFactory.getBuilder(KeyInfoConfirmationDataType.DEFAULT_ELEMENT_NAME);
    //KeyInfoConfirmationDataType keyInfoBuilder = (KeyInfoConfirmationDataType)keyInfoBuilderMethod.buildObject();
    //keyInfoBuilder.??
    //The commented part is what i tried but not successful to add the certificate into the SubjectConfirmationData.


    SAMLObjectBuilder subjectConfirmationBuilder = (SAMLObjectBuilder) builderFactory.getBuilder(SubjectConfirmation.DEFAULT_ELEMENT_NAME);
    SubjectConfirmation subjectConfirmation = (SubjectConfirmation) subjectConfirmationBuilder.buildObject();
    subjectConfirmation.setSubjectConfirmationData(confirmationMethod);

currently get the following output:

<saml2:Subject>
    <saml2:NameID Format="urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress" NameQualifier="CCC">[email protected]</saml2:NameID>
    <saml2:SubjectConfirmation>
        <saml2:SubjectConfirmationData NotBefore="2015-08-16T06:04:54.115Z" NotOnOrAfter="2015-08-16T06:06:54.115Z"/>
    </saml2:SubjectConfirmation>
</saml2:Subject>

i need the saml assertion to contain the keyinfo and the x509Certificate in the SubjectConfirmationData as below:

<saml:Subject>
      <saml:NameID
        Format="urn:oasis:names:tc:SAML:1.1:nameid-format:X509SubjectName">
        [email protected],OU=User,O=NCSA-TEST,C=US
      </saml:NameID>
      <saml:SubjectConfirmation
        Method="urn:oasis:names:tc:SAML:2.0:cm:holder-of-key">
        <saml:SubjectConfirmationData>
          <ds:KeyInfo>
            <ds:X509Data>
              <!-- principal's X.509 cert -->
              <ds:X509Certificate>

          </ds:KeyInfo>
        </saml:SubjectConfirmationData>
      </saml:SubjectConfirmation>
    </saml:Subject>

The above sample assertion can be found in the following linkhere

There was another question on SO here to add the certificate in signature rather than in the subject tag, which is the correct one to follow?
another question is how to generate the value of the certificate, is this based on any particular.crt file .

How fun that you ask, I wrote a blog post on the subject just a couple of weeks ago. Basically you create a KeyInfoGenerator using X509KeyInfoGeneratorFactory

X509KeyInfoGeneratorFactory x509Factory = new X509KeyInfoGeneratorFactory();
KeyInfoGenerator genarator = x509Factory.newInstance();

Then you use the generator to create KeyInfo

KeyInfo keyinfo = generator.generate(credentials);
