Help on JCA

Question

Hello,
I am doing JCA to retrieve srm data.when i build the application in eclipse i am getting
<b>The method getService(String) from the type IPortalComponentRequest is deprecated<b></b>
and at code is
IConnectorGatewayService cgService =
        (IConnectorGatewayService) request.getService(IConnectorService.KEY);
Does any one have idea on this...
regards,
maha
