Hi Uday,
Try this (in my case I'm using that in Background CO that implements IGPBackgroundCallableObject ):
     public static Location logger =
          Location.getLocation(<yourClass>.class);
Catch block:
          } catch (GPInvocationException e) {
               throw new GPTechnicalCallableObjectException(
                    logger,
                    resourceAccessor,
                    "ERROR_PARAMETERS",
                    e);
          } catch (GPEngineException e) {
               throw new GPTechnicalCallableObjectException(
                    logger,
                    resourceAccessor,
                    e.getMessage(),
                    e);
