Is the package exported in the bnd.bnd file for the module?

Hi David H Nebinger, thanks for your reply
I tried as you said like below
@Override
   public void doView(RenderRequest renderRequest, RenderResponse renderResponse)
           throws IOException, PortletException {   try {
       Emp ewmp= EmpLocalServiceUtil.fetchEmp(1);
       System.out.println("details : "+ewmp.getEmpName());
   } catch (Exception e) {
       // TODO Auto-generated catch block
       e.printStackTrace();
   }

   try {
       //VYPGProviderDetails details= VYPGProviderDetailsLocalServiceUtil.getVYPGProviderDetails(1);
       VYPGProviderDetails details= vypgProviderDetailsService.getVYPGProviderDetails(1);
       System.out.println("details =====>: "+details.getProviderName());
   } catch (Exception e) {
       // TODO Auto-generated catch block
       e.printStackTrace();
   }

   super.doView(renderRequest, renderResponse);
   }

   @Reference(service = com.vy.payment.gateway.service.VYPGProviderDetailsLocalService.class)
   protected com.vy.payment.gateway.service.VYPGProviderDetailsLocalService vypgProviderDetailsService; but am getting the below exceptionERROR [http-nio-8080-exec-6][status_jsp:950] com.liferay.portal.kernel.portlet.PortletContainerException: com.liferay.portal.kernel.portlet.PortletContainerException: javax.servlet.ServletException: java.lang.NoClassDefFoundError: com/vy/payment/gateway/service/VYPGProviderDetailsLocalService
please give me some guidance David

You never should be accessing the service classes directly, only the interfaces from the API, and wired into your portlet using @Reference annotations.
