求大神指点——JFinal 无实体的分页

[宸熙宝贝]

JFinal自带的 paginate 分页方法完全不好弄呀，完全调用远程的数据 显示 并分页 本地无实体类 无映射
方法是这样的
Db db=new Db();
public void index() {
Integer pageNumber = getParaToInt("pageNumber");
Page <Record> recordList = db.use("db3").paginate(pageNumber, 10, "select *", "from dbo.FullFileBill()");
if(pageNumber==null){
pageNumber=1;
}
setAttr("recordList", recordList);
render("index.jsp");
}
结果页面直接就500了，提示空指针
