Как вы можете видеть, я использую таблицу решений CSV.protected void checkTheRules(PostponementRequest request) {
StatelessKieSession kieSession = getPostponementRulesContainer().newStatelessKieSession();
//apply the data
PoolInfo pool = request.getPart().getActivePool();
_log.debug("validating date for: courtLocation=" + pool.getCourtLocation() +
", daysBeforeSummons=" + pool.getDaysBeforeSummons() +
", requestDaysAfterSummons=" + request.getRequestDaysAfterSummons() +
", requestDaysAfterOrigSummons=" + request.getRequestDaysAfterOrigSummons() +
", requestedDayOfWeek=" + request.getRequestedDayOfWeek() +
", requestedDayOfMonth=" + request.getRequestedDayOfMonth()
);
List list = new LinkedList();
List parms = Arrays.asList(pool, request, list);
kieSession.execute(parms);
}

Теперь допустим, что мой цикл содержит 50 пунктов, которые я пробегаю. Это 50 отдельных составов хранения в 50 различных потоках. Время от времени они все будут работать, но обычно я получаю следующий раз: < /p>
