以jfinal为基础将数据从数据库中取出，在JSP中用JSTL标签的foreac?报错

--------------------------------------------这是JSP代码

<div class="left">
<div style="width: 960px; height: 90%; display: inline-block;">
<c:forEach items="${page.list}" var="i"  varStatus="status">

<div class="list">
<a src="/image/02.jpg" /></a>
<div class="list-title">
<span><c:out value="${i.goodsname}"></c:out></span>
</div>
<div class="list-text">
<span><c:out value="${i.goodscontents}"></c:out></span>
</div>
<div class="list-button-wc">
<input type="submit" value="查看更多" class="list-button" />
</div>
</div>
</c:forEach>
</div>
      </div>
---------------------------------这是后台-------------------

public void all() {
int cid;
int pageId;


String tempSql = "select t_goods.GOODSID,t_goods.GOODSPHOTO,t_goods.GOODSCONTENTS,t_goods.GOODSNAME";


String getAllStaffSql = "from t_goods";


pageId = getParaToInt("pid");


Page<Goods> goodsPage = Goods.dao.paginate(pageId, 7, tempSql,
getAllStaffSql);
List<Goods> goodsList = goodsPage.getList();
System.out.println(goodsList);


setAttr("page", goodsPage);

setAttr("list", goodsList);
render("/MainView.jsp");
}
数据库用的是Oracle，为什么一运行页面就变成白色，什么都不显示。。。。。没有报错。。求解答。。。
