Axis 1.4 - how to get InternalID of customer from login response

As per documentation with Axis 1.1 we get InternalId of customer in login response in following way:
String userid = getHeader(port, "sessionInfo"); public static String getHeader(NetSuitePortType port, String headerName) {  com.netsuite.webservices.platform.NetSuiteBindingStub stub =   (com.netsuite.webservices.platform.NetSuiteBindingStub) port;  SOAPHeaderElement [] headers = stub.getResponseHeaders();  for (int i=0; i< headers.length; i++)  {   SOAPHeaderElement header = headers[i];   if (header.getName().equals(headerName))   {    Iterator childElements = header.getChildElements();    while (childElements.hasNext())    {     SOAPElement el = (SOAPElement) childElements.next();     return el.getValue();    }   }  }  return null; } Any idea that how we can get that with Axis 1.4.
