Nullpointerexception adding SOAPHeaderElements

Question

I am receiving a NullpointerException adding soap header elements to a soap messagecontext in a handler file. I am trying to add security header information to the header of a soap message calling a web service. I have tried many different methods to do this and I keep going down rabbit holes. I have been working on this for over two weeks. Please help
FOLLOWING IS THE EXCEPTION:
Event: handleRequest
Endpoint Method: CreateAccountCheckingRequest
java.lang.NullPointerException
at MessageHandler.getSOAPHeader(MessageHandler.java:146)
at MessageHandler.logSoapMessage(MessageHandler.java:94)
at MessageHandler.handleRequest(MessageHandler.java:63)
at weblogic.webservice.core.HandlerChainImpl.handleRequest(HandlerChainI
mpl.java:143)
at com.bea.wlw.runtime.jws.call.SoapCall.applyHandlerChain(SoapCall.java
:580)
at com.bea.wlw.runtime.jws.call.SoapHttpCall.invoke(SoapHttpCall.java:11

at com.bea.wlw.runtime.jws.call.SoapHttpCall.invoke(SoapHttpCall.java:79
FOLLOWING IS THE SECTION OF THE MESSAGEHANDLER FILE WHERE THE PROBLEM IS BEING EXPERIENCED:
Line 146 is: SOAPHeaderElement ele1 = (SOAPHeaderElement) header.addHeaderElement(security);
protected void getSOAPHeader(MessageContext mc) throws SOAPException
String headerString;
SOAPMessageContext messageContext = (SOAPMessageContext) mc;
SOAPMessage soapmsg = messageContext.getMessage();
SOAPEnvelope env = soapmsg.getSOAPPart().getEnvelope();
SOAPHeader header = env.getHeader();
Name security = env.createName("Security", "wsse", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd");
SOAPHeaderElement ele1 = (SOAPHeaderElement) header.addHeaderElement(security);
Name must = env.createName("env:mustUnderstand");
ele1.addAttribute(must, "1");
SOAPElement ele2 = (SOAPElement)ele1.addChildElement("usernameToken","wsse");
Name token = env.createName("Id","wsu","http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd");
ele2.addAttribute(token,"Id-dFQDZm_34ewPYtaARIJ_4BfI");
SOAPElement ele3 = (SOAPElement)ele2.addChildElement("Username","wsse");
ele3.addTextNode("weblogic");
ele2.addChildElement("Password","wsse").addNamespaceDeclaration("Type","http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText").addTextNode("weblogic");
Iterator iter = header.getChildElements();
while ( iter.hasNext() )
SOAPHeaderElement element = (SOAPHeaderElement) iter.next();
System.out.println ("---> Header, name = " + element.getElementName() + ", value = " + element.getValue());
StringRuntimeContext stringRuntimeContext = (StringRuntimeContext)PrimitiveContextFactory.create ( element.getValue() );
WorkContextMap map = WorkContextHelper.getWorkContextHelper().getWorkContextMap();
map.put ( element.getElementName().toString(), stringRuntimeContext );
Please, someone, help me with this before I get fired...
