I am calling this code
public List<MarketCatalogue> listMarketCatalogue(MarketFilter filter, Set<MarketProjection> marketProjection,
MarketSort sort, String maxResult, String appKey, String ssoId) throws APINGException {
Map<String, Object> params = new HashMap<String, Object>();
params.put(LOCALE, locale);
params.put(FILTER, filter);
params.put(SORT, sort);
params.put(MAX_RESULT, maxResult);

params.put(MARKET_PROJECTION, marketProjection);
String result = getInstance().makeRequest(ApiNgOperation.LISTMARKE TCATALOGUE.getOperationName(), params, appKey, ssoId);
