jsp报String literal is not properly closed by a double-quote解决方法

jsp报String literal is not properly closed by a double-quote
请各位高人解答一下

<%@page language="java" import="java.util.*" pageEncoding="gbk" %>
<%
String username =(String)session.getAttribute("username");
if(username == null) {
out.println("<script type=\"text/javascript\">");
out.println("alert(\"您还没登录，请登录后再下载\");");
out.println("open(\"login.jsp\",\"_self\");");
out.println("</script>");
}else{
out.println("欢迎会员，请下载");
out.println("<a href=\"logout.jsp\”>退出登录</a>");
}
%>

报错是

exception 

org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 2 in the jsp file: /doDownload.jsp
Generated servlet error:
String literal is not properly closed by a double-quote


谢谢了个位大侠！这是怎么回事？

你这样，里层的双引号全部换成单引号试试。

你好，想问一下，
1，我换成单引号中文会变乱码？怎么调一下？
2，改回双引号还是报同样错误，麻烦解释一下原因！
不甚感激！
