java.lang.ClassNotFoundException: org.opensaml.DefaultBootstrap -

i using opensaml authenticate saml response identity provider (idp). first step, converting dom response idp opensaml xmlobject. using following code:

base64 base64 = new base64(); byte[] base64decodedresponse = base64.decode(responsemessage);  bytearrayinputstream = new bytearrayinputstream(base64decodedresponse);  documentbuilderfactory documentbuilderfactory = documentbuilderfactory.newinstance(); documentbuilderfactory.setnamespaceaware(true); documentbuilder docbuilder = documentbuilderfactory.newdocumentbuilder();  document document = docbuilder.parse(is); element element = document.getdocumentelement();  unmarshallerfactory unmarshallerfactory = configuration.getunmarshallerfactory(); unmarshaller unmarshaller = unmarshallerfactory.getunmarshaller(element);  if (unmarshaller == null)     throw new illegalstateexception("could not obtain saml unmarshaller");  xmlobject obj = unmarshaller.unmarshall(element); if (obj == null || !(obj instanceof response))     throw new illegalstateexception("unmarshaller return not saml response"); 

this code gave me illegalstateexception: not obtain saml unmarshaller. on googling found : opensaml error receiving correct unmarshaller pegerto suggested bootstrapping unmarshaller registers. so, added following code:

try {     defaultbootstrap.bootstrap();     generator = new securerandomidentifiergenerator();  } catch (exception ex) {     ex.printstacktrace(); } 

now giving:
