Я разработал небольшой источник данных pjo, который правильно отображается в отчете birt. Теперь я хотел бы добавить некоторые параметры в pojo для фильтрации возвращаемых им значений.Birt PojoDatasource с параметрами?

Когда я получил это право, я должен сделать следующие шаги в моих POJO:

public void open(Object obj, Map<String, Object> map) { 
    Map<String, Object> mur = (Map<String, Object>) obj; 
    HttpServletRequest request=(HttpServletRequest)mur.get(EngineConstants.APPCONTEXT_BIRT_VIEWER_HTTPSERVET_REQUEST); 
    Date fromDate = getDate(request.getParameter("fromDate")); 
    Date toDate = getDate(request.getParameter("toDate")); 

    .... 
} 

Когда сейчас работает отчет, я получаю следующее исключение. Может кто-нибудь, пожалуйста, дайте мне толчок в правильном направлении?

Thx !!!

ОК, я нашел его. Я думаю, что пример, который я использовал из Интернета, был немного неправильным.

На самом деле мне пришлось использовать карту из «открытого» метода, а не объекта. В, все параметры доступны.

Date fromDate = getDate(map.get("fromDate").toString()); 
Date toDate = getDate(map.get("toDate").toString()); 
String env = map.get("env").toString(); 

ура!
