code: public static TAIResult create(int status, String principal) throws WebTrustAssociationFailedException {
          return new TAIResult(status, principal, null);
      }
docs: <P>
  Create an instance of the result with status, if trust is validated
  and established (should return status <CODE>HttpServletResponse.SC_OK</CODE>,
  if any other status code is return, WebSphere Application Server will stop the
  normal processing and send status code back to caller.) and the authenticated principal.
  <P>
  
  @param status status code, please use <CODE>HttpServletResponse.SC_OK</CODE> if trust is validated and established
  @param principal authenticated principal
  @return TAIResult
  @exception WebTrustAssociationFailedException
  Thrown if there is no authenticated principal when status is <CODE>HttpServletResponse.SC_OK</CODE>
