现在我在java里简单的给POJO对象 user 赋值，然后放到list里，创建 scripted data source 数据源，在数据集的 script:open 里取值是可以的：
importPackage(Packages.test)
emps = DataFactory.getData();
iterator = emps.iterator(); 没有问题，报表正常显示。

但是现在想通过 session 把结果集传过来，在action里直接put到session里 session.put("dataLsit", list);然后 在script:open 里为什么取不到值？
importPackage(Packages.javax.servlet.http);
importPackage(Packages.javax.servlet.ServletContext);

req = reportContext.getHttpServletRequest();
session = req.getSession();
list = session.getAttribute("dataLsit");
iterator = list.iterator();
