OpenSAML user discussion

Hi, I am new in using opensaml, I want to right a simple assertion and 
print it, but I get [saml:Assertion: null], this is my code:
public static void main(String[] args) throws Exception {
  
       org.opensaml.DefaultBootstrap.bootstrap();
      
   // Get the builder factory
   XMLObjectBuilderFactory builderFactory = 
Configuration.getBuilderFactory();

   // Get the assertion builder based on the assertion element name
   SAMLObjectBuilder<Assertion> builder = 
(SAMLObjectBuilder<Assertion>)(builderFactory.getBuilder(Assertion.DEFAULT_ELEMENT_NAME));

   // Create the assertion
   Assertion assertion = builder.buildObject();
   // set Id
   assertion.setID("12345");
   IssuerBuilder ib = new IssuerBuilder();
   // set Issuer
   Issuer i = ib.buildObject();
   i.setValue("Hello World");
   assertion.setIssuer(i);
   // set IssueInstant
   //DateTime dt = new DateTime();
   //assertion.setIssueInstant(dt);
  
  
   // Get the marshaller factory
   MarshallerFactory marshallerFactory = 
Configuration.getMarshallerFactory();

   // Get the Assertion marshaller
   Marshaller marshaller = marshallerFactory.getMarshaller(assertion);

   // Marshall the Assertion
   Element assertionElement = marshaller.marshall(assertion);
  
   System.out.println(assertionElement.toString());



Thanks.
