一个快让我发狂的问题
这是我的THML内容
<html>
<head>
<meta http-equiv= "Content-Type " content= "text/html; charset=UTF-8 ">
<title> Insert title here </title>
</head>
<body>
<form method= "post " action= "jbean_jsp.jsp ">
<pre>
<p align= "center ">
用户名： <input type= "text " name= "username " size= "20 ">
密 码： <input type= "password " name= "pwd " size= "20 ">
<input type= "submit " value= "提交 " name= "sb ">
</p>
</pre>
</form>
</body>
</html>
这个是我的JSP内容
<%@ page language= "java " contentType= "text/html; charset=UTF-8 "
pageEncoding= "UTF-8 " import= "java.beans.* " %>
<jsp:useBean id= "test " class= "bean.jteat " scope= "page ">
</jsp:useBean>
<html>
<head>
<meta http-equiv= "Content-Type " content= "text/html; charset=UTF-8 ">
<title> Insert title here </title>
</head>
<body>
<jsp:setProperty name= "test " property= "* "/>
username:
<jsp:getProperty name= "test " property= "username "/>
password:
<jsp:getProperty name= "test " property= "pwd "/>
<%
out.print(test.getUsername());
%>
</body>
</html>
下面这个是我的JAVA内容
package bean;
public class jteat {
private String username;
private String pwd;
public void setUsername(String username){
this.username = username;
}
public String getUsername(){
return this.username;
}
public String getPwd() {
return pwd;
}
public void setPwd(String pwd) {
this.pwd = pwd;
}
}
我已经试了N多个了，他都是报这错
严重: Servlet.service() for servlet jsp threw exception
org.apache.jasper.JasperException: /jdbc_jsp/jbean_jsp.jsp(3,1) The value for the useBean class attribute bean.jteat is invalid.
我现在都想杀人了，郁闷，也不知道哪错了，请哪位大哥帮忙解决下！！！！！！！！！！！！

你的程序没有任何问题，运行bean也不需要设置，建议修改jsp文件名 <form method= "post " action= "jbean_jsp.jsp "> 至 <form method= "post " action= "jbean.jsp ">
