小弟刚学jsp是个新手，在使用javabean是老是报错，请各位大哥帮小弟指点，小弟不胜感激。我的调用页面如下：
<%@ page contentType= "text/html; charset=gb2312 " language= "java " import= "java.sql.* " errorPage= " "%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN " "http://www.w3.org/TR/html4/loose.dtd ">
<html>
<jsp:useBean id= "D " class= "javabean " scope= "application "/>
<head>
<meta http-equiv= "Content-Type " content= "text/html; charset=gb2312 ">
<title> 无标题文档 </title>
</head>
<body>
<jsp:setProperty name= "D " property= "* "/>
name:
<jsp:getProperty name= "D " property= "name "/>
password:
<jsp:getProperty name= "D " property= "password "/>
</body>
</html>
报错页面如下：

[解决办法]
<jsp:useBean id= "D " class= "javabean " scope= "application "/>
没找到class= "javabean "中的javabean这个bean，这个是需要你的具体的bean的class名字，并且你需要在前面import
[解决办法]
你是用什么开发的JAVABEAN
你那错误提示是没发现JAVABEAN
你自己先把书好好看一下
不过我建议你用MYECLIPSE学JSP
[解决办法]
你最好把你的JAVABEAN代码贴出来
<jsp:useBean id= "D " class= "javabean " scope= "application "/>
class是你JAVABEAN的名字
<jsp:getProperty name= "D " property= "password "/>
得到你javabean中的属性值，你在前面import 一下。
[解决办法]
你加一个包试试
