Hooking with action class

public class FeeAction extends BaseAction {
   ....
   ....

   //the usual struts action of way of calling a service.
   private static final FeeServiceFacade feeServiceFacade = new WebTierFeeServiceFacade();

   //would be available only if FeeContext.xml is loaded onto spring container.
   private FeeServiceFacade getFeeServiceFacade() {
       Object svcFacade = MifosApplicationContext.getBean("feeServiceFacade");
       return (svcFacade != null) ? (FeeServiceFacade) svcFacade : feeServiceFacade;
   }


   public ActionForward get(ActionMapping mapping, ActionForm form, HttpServletRequest request,
           HttpServletResponse response) throws Exception {
       FeeDto feeDto = getFeeServiceFacade().getFeeDetails(((FeeActionForm) form).getFeeIdValue());
       request.setAttribute("model", feeDto);
       return mapping.findForward(ActionForwards.get_success.toString());
   }
   ....
   ....
}

org.mifos.accounts.fees.servicefacade.MifosApplicationContext is an spring ApplicationContextAware bean. Use the static method getBean(beanName) to aquire an instance of the bean. Note, you should do a null check like above and return instance of legacy code if not found.

FeeContext.xml has been added to the web.xml. If you remove it from "contextConfigLocation" of context-param, the new classes will not be loaded onto spring context.
