导入类的问题,怎么也想不明白
工作目录为webapps\zz\ 
 自己写的类password.class放在webapps\zz\WEB-INF\classes\zz下面 
 package   zz;   
 import   java.io.*;   
 public   class   password 
 { 
 	private   String   filePath; 
 	private   String   password;   
 	public   password(String   filePath)   { 
 		this.filePath   =   filePath; 
 	}   
 	public   String   getPassword()   { 
 		try   { 
 			FileInputStream   inputFile   =   new   FileInputStream(filePath); 
 			ObjectInputStream   in   =   new   ObjectInputStream(inputFile); 
 			password   =   (String)in.readObject(); 
 			in.close(); 
 			inputFile.close(); 
                         }   catch(Exception   e)   { 
 			e.printStackTrace(); 
                         } 
 		return   password; 
 	}   
 	public   void   setPassword(String   password)   { 
 		try   { 
 			FileOutputStream   outputFile   =   new   FileOutputStream(filePath); 
 			ObjectOutputStream   out   =   new   ObjectOutputStream(outputFile); 
 			out.writeObject(password); 
 			out.flush(); 
 			out.close(); 
 			outputFile.close(); 
 		}   catch   (
IOException   ioe)   { 
 			ioe.printStackTrace(); 
 		} 
 	} 
 }     
 JSP页面test.jsp放在webapps\zz\pages\11\下 
  <%@   page   contentType= "text/html;   charset=gb2312 "   language= "java "   import= "zz.* "%>  
  <!DOCTYPE   html   PUBLIC    "-//W3C//DTD   XHTML   1.0   Transitional//EN "    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">  
  <html   xmlns= "http://www.w3.org/1999/xhtml ">  
  <head>  
  <meta   http-equiv= "Content-Type "   content= "text/html;   charset=gb2312 "   />  
  <title> 无标题文档 </title>  
  </head>  
  <% 
 	String   password   =    "111 "; 
 	out.println(password);  	 
 	password   pass   =   new   password( "psd.ini "); 
 	//pass.setPassword(password); 
 %>  
  <body>  
  </body>  
  </html>    
 为什么运行时就出错,错误如下
