Java 带参数的Birt PojoDatasource？

我开发了一个小pjo数据源，它正确地显示在birt报告中。 现在，我想向pojo添加一些参数，以过滤pojo返回的值

如果我做对了，我必须在pojo中执行以下步骤：

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"));

    ....
}

public void open（对象对象对象、地图）{
Map mur=（Map）obj；
HttpServletRequest=（HttpServletRequest）mur.get（EngineConstants.APPCONTEXT\u BIRT\u VIEWER\u HTTPSERVET\u request）；
Date fromDate=getDate（request.getParameter（“fromDate”）；
Date toDate=getDate（request.getParameter（“toDate”）；
....
}

现在运行报告时，我遇到以下异常。 谁能帮我往正确的方向推一下吗

谢谢
