MessageContext.getCurrentContext() is null

[Plorks mail]

Hello all
I have a web service with some methods - when i publish it not all methods 
will be exposed, but those that are exposed will call the unexposed methods

One unexposed method is addSOAPHeader, which gets called when a user is 
validated.

When I call the addSOAPHeader method i need to call the 
handleRequest/Response method with the MessageContext.

I'm doing it like this but doesn't work - the MesaageContext is null
MessageContext context = MessageContext.getCurrentContext();
handleResponse(context);
Am i missing something in my addSOAPHeader method?
Any help greatly appreciated


public static String addSOAPHeader(String token) throws Exception
{
 Service service = new Service();
 Call call = (Call)service.createCall();
 SOAPHeaderElement tokenHeader = new SOAPHeaderElement("","TokenHeader");
 tokenHeader.setObjectValue(token);
 call.addHeader(tokenHeader);
 MessageContext context = MessageContext.getCurrentContext();
 SOAPHandler.handleRequest(context);
 return token;
}

SOAPHandler class
public void invoke(MessageContext msgContext) throws AxisFault
   {
    handleResponse(msgContext);
       super.invoke(msgContext);
   }
public static boolean handleResponse(MessageContext msgContext)
   {
       try
       {
           Message message = msgContext.getResponseMessage();
           SOAPEnvelope responseEnvelope = message.getSOAPEnvelope();
           SOAPHeaderElement headerElement = 
responseEnvelope.getHeaderByName("","TokenHeader");

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

               // make sure the headerElementValue is valid
               validateTokenValue(headerElementValue);
           }
           else
           {
               // something's gone wrong
           }
       }
       catch(Exception e)
       {
           System.out.println(e);
       }
       return true;
   }
   public static boolean handleRequest(MessageContext msgContext)
   {
          try
       {
           Message message = msgContext.getRequestMessage();
           SOAPEnvelope requestEnvelope = message.getSOAPEnvelope();
           SOAPHeaderElement headerElement = 
requestEnvelope.getHeaderByName("","TokenHeader");

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

               // make sure the headerElementValue is valid
               validateTokenValue(headerElementValue);
           }
           else
           {
               // something's gone wrong
           }
       }
       catch(Exception e)
       {
           System.out.println(e);
       }
       return true;
   }
