jsp「無法編譯」和「無法解析到某個類型」

我有一個jsp文件，它從我的包文件夾中導入我的classes目錄中。當我嘗試使用它時，我得到「無法編譯」和「無法解析爲類型」錯誤。這是我的代碼。jsp「無法編譯」和「無法解析到某個類型」

<%@ page language="java" import="cs5530.*" %> 
<html> 
<head> 
<script type="text/javascript"> 
function showInvalid() 
{ 
    document.getElementById("invalid").style.display = 'block'; 
    document.getElementById("loginForm").reset(); 
} 
</script> 
</head> 
<body> 
<p>Welcome to FlixNet. Sign In</p> 
<form name="loginForm" method="post" action="index.jsp"> 
    User Name: <input type="text" name="username"><br> 
    Password: <input type="Password" name="password"><br> 
    <input type="submit" value="Submit"> 
    <div id="invalid" style="display:none"> 
     <p>Invalid username or password</p> 
    </div> 
</form> 
<% 
Connector con = new Connector(); 
con.closeConnection(); 
%> 
</body> 
</html>

這是錯誤

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

Connector cannot be resolved to a type 
20:  </div> 
21: </form> 
22: <% 
23: Connector con = new Connector(); 
24: con.closeConnection(); 
25: %> 
26: </body>

這是我的文件結構

public_html 
    index.jsp 
    |WEB-INF 
     |classes 
      mysql.jar 
      |cs5530 
       Connector.java 
       Connector.class 
       other java and class files.

我的連接器類是包CS5530下，所以這不是問題。連接器類是一個簡單的數據庫連接器類，我已經測試過，它的工作原理。

你是否在jar下？它應該在lib下。 – JRR
