Hi In my opinion you should create a factory class in which you choose proper instance to select from database depend on given locale. for example, if you support two locales you should have something like this: interface Country {} class CountryEnglish implement Country{} class CountryFrench implements Country{} then your factory class: class CountryFactory { static Country getInctance(int localeId){ if(localeId == ENGLISH){ return new CountryEnglish(); } if(localeId == FRENCH){ return new CountryFrench(); } } } and you should put EntityManager in those two class and call them to select from database instead of calling "em" directly. hope this help.
