Any help reatly appreciated

public void invoke(MessageContext msgContext) throws AxisFault
   {
       handleRequest(msgContext);
       super.invoke(msgContext);
   }
   public boolean handleResponse(MessageContext msgContext)
   {
       try
       {
           Message message = msgContext.getRequestMessage();
           SOAPEnvelope requestEnvelope = message.getSOAPEnvelope();
           SOAPHeaderElement headerElement = 
requestEnvelope.getHeaderByName("http://domain","TokenHeader";);

           if (headerElement != null)
           {
               String headerElementValue = 
(String)headerElement.getValue();

               // make sure the headerElementValue is valid
               validateTokenValue(headerElementValue);
           }
           else
           {
               // something's gone wrong
               // no header TokenHeader found, therefore we need to create 
a header element and return to client

               // get userName and password
               // pass to db to validate
               //SOAPHeaderElement responseHeaderElement = new 
SOAPHeaderElement("http://domain","TokenHeader";);
               //responseHeaderElement.setObjectValue(sTokenValue);
           }
       }
       catch(Exception e)
       {
           System.out.println(e);
       }

       return true;
   }
   public boolean handleRequest(MessageContext msgContext)
   {
       try
       {
           //SOAPEnvelope responseEnvelope = 
msgContext.getResponseMessage().getSOAPEnvelope();
           Message message = msgContext.getResponseMessage();
           SOAPEnvelope responseEnvelope = message.getSOAPEnvelope();

       }
       catch(Exception e)
       {
           System.out.println(e);
