关于forward的用法一些问题
<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>
<%
String username = "小明";
%>
<jsp:forward page="forward_demo02.jsp">
<jsp:param name="name" value="<%=username%>" ;/>
<jsp:param name="info" value="info" ;/>

</jsp:forward>


这是第一个forward_demo01.jsp


<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>

<h1>
这是跳转之后的页面
</h1>
<h2><%=request.getParameter("name")%></h2>
<h2><%=request.getParameter("info")%></h2>
这是第2个forward_demo02.jsp 我运行之后出现500错误
org.apache.jasper.JasperException: Unable to load class for JSP

这是什么原因？

------解决方案--------------------
是直接粘贴的，去掉了参数后面的分号，第二个jsp名字改了一下而已

探讨

引用:

我在我这里试没问题呀
Java code
<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>
<%
String username = "小明";
%>
<jsp:forward page="forward.jsp">
<jsp:param name="name" v……

12楼是对的哦，去掉分号就可以的。
