Question

jsp中<% @page import="java.util.*" %>问题

这是我的源程序:
<% @page import="java.util.*" %>
<%
Enumeration varobj=request.getParameterNames();
int count=0;
out.println("取得变量名为:");
while(varobj.hasmoreelements())
{
count++;
out.println("<");
out.println(varobj.nextelement());
out.println(">");
}
out.println("<P>共发送"+count+"项信息");
%>
下面是出错信息
An error occurred at line: 9 in the jsp file: /jsptest/getparameternames.jsp
Generated servlet error:

各位大哥!!怎么解决啊....

Answer 1

@＠这是2个一个是全角字符/一个是半角字符!
2个在计算机里面不是一个字!
在我们生活中我们认为它门是一个!
你按shift+空格可以在全角和半角之间切换

Answer 2

<%@ page import="java.util.*" %>
这样

Answer 3

你是不是输入的中文＠？
