How to get an operation Name in a Requstor Handler

I am trying to write a Service requestor Handler. Inside the Handler's invoke method, I want to get the method name of service provider:

I can get an operation name from a MessageContext as follows.

public void invoke(MessageContext msgContext) throws AxisFault

{

Handler serviceHandler = msgContext.getService();

Message msg=msgContext.getRequestMessage();

SOAPEnvelope envelope=msg.getSOAPEnvelope();

Element envElement=envelope.getAsDOM();

Document doc= envelope.getAsDocument();

String operationName=mygetOperation(doc);

}

Is there any other way that I can get an operation name and its expected passing parameters in my Handlers from a MessageContext?

I tried this, but it gives me NULL pointer exception error.

OperationDesc op =msgContext.getOperation();

Method t= op.getMethod();

System.out.println(t.getName())===>java.lang.NullPointerException

I really appreciate your input.
