Groovy Script OIM12 Trying to Update user attributes

HI

We are on OIm12 and using a DBAT Connector am trying to update user attributes.

I have this code which is not working.It is not even creating userIntf instance

tcUserOperationsIntf userIntf = ((tcLookupOperationsIntf)(tcUtilityFactory.getLocalUtility(XLDatabase.getInstance().getDataBase(),"Thor.API.Operations.tcUserOperationsIntf")));

               //Update Flag

                   System.out.println("DEBUG :comparing Flags");

               def userAttrs = userIntf .getUserAttributes(usrKey);

               System.out.println("Done 1");

               if ("Active Flag".equals(flag)) {

                  userAttrs.put("Active_Flag", "Y");

                  userIntf.setUserAttributes(usrKey, userAttrs);

                  System.out.println("Updated flag to Y");

               }
