显示数据
不会显示任何内容，只是一个空白页面
据推测，这将显示用户搜索的条目的信息。请帮忙
首先。。。我做JSP翻译对吗？在JSP中使用Scriptlets方法
通过执行以下操作导入对象项。。套餐。*
无需导入java包
将此代码放在正文上
<% Item item = (Item) request.getAttribute("invenItem");
if (item != null) { %>
Stock ID : <%= item.getStockID() %><br>
Name : <%= item.getItemName() %><br>
Unit Price: <%= item.getUnitPrice() %><br>
On Stock : <%= item.getOnStock() %><br>
<% } else { %>
<%@ include file ="DataForm.html" %><br>
<%@ include file ="ItemEntry.html" %>
<% } %>
股票ID:
名称：
单价：
库存：
有关解释，请按照巴鲁克先生的建议阅读。
然后尝试使用javabeans和EL创建JSP
注意：您的代码中已经有一个javabeans<代码>
