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
org.apache.jasper.JasperException: Unable to compile class for JSP:
An error occurred at line: 12 in the jsp file: /pages/11/test.jsp
password cannot be resolved to a type
9: String password = "111 ";
10: out.println(password);
11:
12: password pass = new password( "psd.ini ");
13: //pass.setPassword(password);
14: %>
15: <body>
